Description:
TECHNICAL FIELD 
       [0001]    The disclosure relates to the field of mobile terminal techniques, and in particular to a method for application icon management in a mobile terminal, and a mobile terminal. 
       BACKGROUND 
       [0002]    With the upgrading of communication products, a mobile terminal such as a mobile phone or a Personal Digital Assistant (PDA) has become an indispensable communication tool, and various convenient and recreational applications appear on a mobile terminal. 
         [0003]    On an existing mobile terminal, icons of various applications are either displayed all in one screen or displayed in multiple screens. Although icon display by multiple screens can facilitate a user in finding an application to some extent, but an existing method for application icon management in a mobile terminal has the following disadvantages: 
         [0004]    (1) display of icons of various applications is not managed by class; 
         [0005]    (2) one application icon management operation can handle only one icon at a time, instead of batch management of multiple icons; 
         [0006]    (3) the icon of an application can be moved only after the application is installed; 
         [0007]    (4) a user can complete a move of an icon of an application only after dragging the icon to a target screen.

         [0062]    In an embodiment, after the icon object to be moved is moved successfully to the area on the rule graph, the table mapping a class of applications to a screen, the table mapping an application to a class of applications, or the table mapping an application to a screen may be updated. 
         [0063]    With the method for application icon management in a mobile terminal according to the disclosure, icons of installed applications are managed rapidly by screen or by class on a respective rule graph, such that with the disclosure, compared with an existing method for application icon management in a mobile terminal, icon management is simplified, and batch management and multi-mode management of icons of applications are achieved, thereby greatly facilitating application icon management by a user. 
         [0064]      FIG. 2  is a flowchart of managing icon-display-by-screen by moving a class of applications in a method for application icon management in a mobile terminal according to an embodiment of the disclosure. As shown in  FIG. 2 , the flow of managing icon-display-by-screen by moving a class of applications according to the disclosure includes steps as follows. 
         [0065]    In Step S 201 , an icon object is moved. 
         [0066]    In an embodiment, after information on a class to which an application belongs is preset in the mobile terminal, and a table of mapping relation among a class of applications, a screen, and an application is established, an icon object of a class of applications or an icon of an application is dragged into a target screen or a target class of applications. 
         [0067]    In Step S 202 , it is determined according to an icon object moving instruction whether the icon object is a class of applications or an icon of an application. 
         [0068]    In an embodiment, when the icon object is moved, the type of the icon object (a class of applications or an icon of an application) needs to be determined in the first place according to the icon object moving instruction, and when the icon object is a class of applications, the flow goes to step S 203 . 
         [0069]    In Step S 203 , information on a single-layer annular graph marked with sequence numbers of screens is acquired; and space remaining in each screen is calculated and compared with space to be occupied by the class of applications. 
         [0070]    In an embodiment, when it is determined that the icon object is a class of applications, information on a single-layer annular graph marked with sequence numbers of screens is acquired, and space remaining in each screen is calculated and compared with space to be occupied by the class of applications. Here, the information on the single-layer annular graph may include a total size of the graph, a total number of screens in the mobile terminal, size of an area containing a sequence number of a screen, an identifier of a color of an area, an identifier of a color of storage space occupied by each class of applications and icons of applications belonging to the each class in a screen, and the like. 
         [0071]    In Step S 204 , the single-layer annular graph marked with sequence numbers of screens is displayed on a current screen. 
         [0072]    In an embodiment, the single-layer annular graph displayed here, as shown in  FIG. 4 , includes 4 screens with sequence numbers  1 ,  2 ,  3 ,  4 , respectively; and areas containing the sequence numbers of screens may be distinguished from each other by color. When there is enough space remaining in a screen, as calculated by the mobile terminal, for storing icons of all applications belonging to the class of applications, the sequence number of the screen is shown in bright yellow. When no screen is found with sufficient free space, as calculated by the mobile terminal, for storing icons of applications belonging to the class of applications, the sequence number of the screen is shown in black. Here, sequence numbers of screens  1 ,  3 ,  4  are shown in bright yellow, indicating that each of screen  1 , screen  3 , and screen  4  has sufficient free space for storing icons of all applications belonging to the class of applications. The sequence number of screen  2  is shown in black, indicating that the screen  2  has insufficient free space for storing icons of all applications belonging to the class of applications. 
         [0073]    In Step S 205 , the class of applications is moved into an area containing a sequence number of a target screen in the single-layer annular graph, and is then released. 
         [0074]    In Step S 206 , it is determined whether there is enough space remaining in the target screen for storing the class of applications; if there is, the flow goes to step S 207 ; otherwise if there is insufficient space, the flow goes to Step S 211 . 
         [0075]    In an embodiment, it is detected whether the sequence number of the target screen is shown in a bright yellow font. If the sequence number of the target screen is shown in a bright yellow font, it means that there is enough space remaining in the target screen for storing the class of applications. Otherwise if the sequence number of the target screen is not shown in a bright yellow font, it means that space remaining in the target screen is insufficient for storing the class of applications, and a user may be notified that space remaining in the target screen is insufficient for storing the class of applications. 
         [0076]    As shown in  FIG. 4 , sequence numbers of screens  1 ,  3 ,  4  are shown in a bright yellow font, and the sequence number of screen  2  is shown in a black font. A class of applications in the screen  1  can be moved to the area containing the sequence number  4  or the area containing the sequence number  3 , but can not be moved to the area containing the sequence number  2 . 
         [0077]    In Step S 207 , the area containing the sequence number of the target screen in the single-layer annular graph is highlighted. 
         [0078]    In an embodiment, for example, as shown in  FIG. 4 , if a class of applications in the screen with sequence number  1  is moved to the area containing the sequence number  4 , then the area containing the sequence number  4  will be highlighted, indicating that the class of applications is moved successfully. 
         [0079]    In Step S 208 , information on the area containing the sequence number of the target screen is recorded, an icon management message corresponding to the move of the class of applications is sent, and a table Class_Screen is updated. 
         [0080]    In an embodiment, after the class of applications is moved successfully, information on the area containing the sequence number of the target screen is recorded, and an icon management message is sent to a managing module of the mobile terminal. The icon management message includes an icon management type MsgType 2, indicating that the current moving operation involves move of a class of applications. After receiving the icon management message, the managing module updates the table Class_Screen, that is, updates the mapping relation between a class of applications and a screen. 
         [0081]    In Step S 209 , application class layout displayed on the current screen and application class layout displayed on the target screen are refreshed. 
         [0082]    In an embodiment, displayed layout of any class of applications on the current screen and on the target screen, and of icons of applications belonging to the any class of applications, are refreshed according to the table Class_Screen updated in step S 208 . 
         [0083]    In Step S 210 , display of the single-layer annular graph is cancelled. 
         [0084]    In an embodiment, when no class of applications is moved within a preset period of time, display of the single layer annular graph is cancelled. 
         [0085]    In Step S 211 , a user is notified that space remaining in the target screen is insufficient for storing the class of applications. 
         [0086]    If it is determined in Step S 206  that space remaining in the target screen is insufficient for storing the class of applications, a notification that space remaining in the target screen is insufficient for storing the class of applications is provided on the current screen. 
         [0087]      FIG. 3  is a flowchart of managing icon-display-by-screen or icon-display-by-class by moving an icon of an application in a method for application icon management in a mobile terminal according to an embodiment of the disclosure. As shown in  FIG. 3 , the flow of managing icon-display-by-screen or icon-display-by-class by moving an icon of an application according to the disclosure includes steps as follows. 
         [0088]    In Step S 301 , an icon object is moved. 
         [0089]    In an embodiment, after information on a class to which an application belongs is preset in the mobile terminal, and a table of mapping relation among a class of applications, a screen, and an application is established, an icon object of a class of applications or an icon of an application is dragged into a target screen or a target class of applications. 
         [0090]    In Step S 302 , it is determined according to an icon object moving instruction whether the icon object is a class of applications or an icon of an application. 
         [0091]    In an embodiment, when the icon object is moved, the type of the icon object (a class of applications or an icon of an application) needs to be determined in the first place according to the icon object moving instruction, and when the icon object is an icon of an application, the flow goes to step S 303 . 
         [0092]    In Step S 303 , information on a double-layer annular graph marked with sequence numbers of screens and classes of applications is acquired, and space remaining in each screen is calculated and compared with space to be occupied by the class of applications. 
         [0093]    In an embodiment, when it is determined that the icon object is an icon of an application, information on the double-layer annular graph marked with sequence numbers of screens and classes of applications is acquired, and space remaining in each screen is calculated and compared with space to be occupied by the class of applications. 
         [0094]    Here, the information on the double-layer annular graph may include: a total size of the graph; a total number of screens in the mobile terminal; any class of applications already in each screen, and a number of classes of applications already in each screen; size of an area containing a class of applications; size of an area containing a sequence number of a screen; an identifier of a color of an area, an identifier of a color of storage space occupied by any class of applications and icons of applications belonging to the class in a screen, and the like. 
         [0095]    In Step S 304 , the double-layer annular graph marked with sequence numbers of screens and classes of applications is displayed on a current screen. 
         [0096]    In an embodiment, the double-layer annular graph displayed here, as shown in  FIG. 5 , includes four classes of applications, namely, everyday, office, game and system. Classes of applications displayed in a same screen occupy continuous areas in the double-layer annular graph and the continuous areas are in the same color. In an embodiment, the two classes of everyday and office are located in screen  1 , the game is located in screen  2 , the system is located in screen  3 , and currently no icon of an application belonging to a class of applications is stored in screen  4 . When there is enough space remaining in a screen, as calculated by the mobile terminal, for storing the icon of the application, the sequence number of the screen and any class of applications in the screen are shown in bright yellow. When no screen is found with sufficient free space, as calculated by the mobile terminal, for storing the icon of the application, the sequence number of the screen and any class of applications in the screen are shown in black. Here, the classes “everyday” and “office” and the sequence number “ 1 ” of the screen containing the classes “everyday” and “office” are in a bright yellow font; the class “system” and the sequence number “ 3 ” of the screen containing the class system are in a bright yellow font too; but class “game” and the sequence number “ 2 ” of the screen containing class game are in a black font. This indicates that the icon of the application may be stored in either screen  1  or screen  3 , but may not be stored in screen  2 , as space remaining in screen  2  is insufficient. 
         [0097]    In Step S 305 , the icon of the application is moved into an area containing a sequence number of a target screen or into an area containing a target class of applications in the double-layer annular graph, and is then released. 
         [0098]    In Step S 306 , it is determined whether the area contains the sequence number of a target screen or contains a target class of applications; If the area contains a target class of applications, the flow goes to Step S 307 ; otherwise if the area contains the sequence number of a target screen, the flow goes to Step S 313 . 
         [0099]    In an embodiment, after the icon of the application is moved into an area containing a sequence number of a screen or containing a class of applications in the double-layer annular graph, and is then released, it is detected whether the area is occupied by a class of applications or a sequence number of a screen. If the area is occupied by a class of applications, the flow goes to Step S 307 . If the area is occupied by a sequence number of a screen, the flow goes to Step S 313 . 
         [0100]    As shown in  FIG. 5 , the icon of an application belonging to the class “system” in screen  3  may be moved to an area containing the sequence number “ 1 ” or “ 4 ”, or to an area containing the class “everyday” or “office” in screen  1  (namely, to an area with a bright yellow font); but cannot be moved to an area containing the sequence number “ 2 ” or to an area containing the class “game” (namely, cannot be moved to an area with a black font). 
         [0101]    In Step S 307 , it is determined whether there is enough space remaining in a screen containing the target class of applications for storing the icon of the application; if space remaining in the target screen is sufficient for storing the icon of the application, the flow goes to step S 308 ; otherwise if space remaining in the target screen is insufficient for storing the icon of the application, the flow goes to Step S 312 . 
         [0102]    In an embodiment, it is detected whether the target class of applications is shown in a bright yellow font, if the target class of applications is shown in a bright yellow font, it means that there is enough space remaining for storing the icon of the application. Otherwise if the target class of applications is not shown in a bright yellow font, it means that space remaining is insufficient for storing the icon of the application. 
         [0103]    In Step S 308 , the area containing the target class of applications in the double-layer annular graph is highlighted. 
         [0104]    In Step S 309 , information on the area containing the target class of applications is recorded, and an icon management message corresponding to the move of the icon of the application is sent, and a table of mapping relation corresponding to the move of the icon of the application is updated. 
         [0105]    In an embodiment, after the icon of the application is moved successfully, the information on the area containing the target class of applications is recorded, and the icon management message corresponding to the move of the icon of the application is sent to a managing module of the mobile terminal. The icon management message includes an icon management type MsgType 3, indicating that the current moving operation involves move of an icon of an application into a target class of applications. After receiving the icon management message, the managing module of the mobile terminal checks the table App_Class to determine whether a mapping relation between the application and a class of applications exist, i.e., checks whether the application has been classified. If the application has not been classified, then the table App_Screen is called, and a mapping relation between the application and a screen in the table App_Screen is deleted; in addition, the table App_Class is called, and a mapping relation between the application and the target class of applications is added in the table App_Class; when the application is previously classified, the table App_Class is called, and the mapping relation between the application and a class of applications is updated. 
         [0106]    In Step S 310 , application icon layout displayed on a current screen and application icon layout displayed on a target screen are refreshed. 
         [0107]    In an embodiment, application icon layout displayed on the current screen and application icon layout displayed on the target screen are refreshed according to a table updated in step S 309 . 
         [0108]    In Step S 311 , display of the double-layer annular graph is cancelled. 
         [0109]    In an embodiment, when no application icon is moved within a preset period of time, display of the double-layer annular graph is cancelled. 
         [0110]    In Step S 312 , a user is notified that space remaining in the screen containing the target class of applications is insufficient for storing the icon of the application. 
         [0111]    In an embodiment, if it is determined in Step S 307  that space remaining in the screen containing the target class of applications is insufficient for storing the icon of the application, then a notification that space remaining in the screen containing the target class of applications is insufficient for storing the icon of the application is provided on the current screen. 
         [0112]    In Step S 313 , it is determined whether there is enough space remaining in the target screen for storing the icon of the application; if there is enough space, the flow goes to step S 314 ; otherwise if space remaining in the target screen is insufficient for storing the icon of the application, the flow goes to Step S 316 . 
         [0113]    In an embodiment, when the mobile terminal detects that the area where the icon of the application is released contains a sequence number of a screen, it is determined whether there is enough space remaining in the target screen for storing the icon of the application. That is, it is detected whether the sequence number of the target screen is shown in a bright yellow font. If the sequence number of the target screen is shown in a bright yellow font, it means that there is enough space remaining in the target screen for storing the icon of the application. Otherwise if the sequence number of the target screen is not shown in a bright yellow font, it means that space remaining in the target screen is insufficient for storing the icon of the application. 
         [0114]    In Step S 314 , the area containing the sequence number of the target screen in the double-layer annular graph is highlighted. 
         [0115]    In Step S 315 , information on the area containing the sequence number of the target screen is recorded, and an icon management message corresponding to the move of the icon of the application is sent, and a table of mapping relation corresponding to the move of the icon of the application is updated. 
         [0116]    In an embodiment, after the icon of the application is moved successfully, the information on the area containing the sequence number of the target screen is recorded, and the icon management message corresponding to the move of the icon of the application is sent to the managing module of the mobile terminal. The icon management message includes an icon management type MsgType 4, indicating that the current moving operation involves move of an icon of an application into a target screen. After receiving the icon management message, the managing module of the mobile terminal checks the table App_Class to determine whether a mapping relation between the application and a class of applications exist, i.e., checks whether the application has been classified. If the application has not been classified, then the table App_Screen is called, and a mapping relation between the application and a screen is updated; when the application is previously classified, the table App_Class is called, and the mapping relation between the application and any class of applications in the table App_Class is deleted, and the table App_Screen is called to add a mapping relation between the application and the target screen in the table App_Screen. Then application class layout and application icon layout displayed on a screen is refreshed according to an updated table. When no application icon is moved within a preset period of time, display of the double-layer annular graph is cancelled. 
         [0117]    In Step S 316 , a user is notified that space remaining in the target screen is insufficient for storing the icon of the application. 
         [0118]    If it is determined in Step S 313  that space remaining in the target screen is insufficient for storing the icon of the application, a notification that space remaining in the target screen is insufficient for storing the icon of the application is provided on the current screen. 
         [0119]      FIG. 6  is a flowchart, in installing a new application, of setting a class to which the new application belongs and directly managing display of the icon of the new application in a method for application icon management in a mobile terminal according to an embodiment of the disclosure. As shown in  FIG. 6 , the flow, in installing a new application, of setting a class to which the new application belongs and directly managing display of the icon of the new application includes steps as follows. 
         [0120]    In Step S 601 , a package file for installing a new application is read. 
         [0121]    In an embodiment herein, in installing a new application, a mobile terminal will read a package file for installing the new application, where the package file may include information such as an icon of the application, a name of the package for installing the application and a hardware environment needed for installing the application. 
         [0122]    In Step S 602 , space remaining in each screen is calculated. 
         [0123]    In Step S 603 , it is determined whether there is enough space remaining in a screen for storing the icon of the new application; if there is enough space remaining in a screen for storing the icon of the new application, the flow goes to step S 604 ; otherwise if no screen has enough free space for storing the icon of the new application, the flow goes to Step S 610 . 
         [0124]    In Step S 604 , a sequence number of the screen with free space sufficient for storing the icon of the new application, and a class of applications contained in the screen with the sequence number, are read. 
         [0125]    In an embodiment, when it is detected that there is enough space remaining in a screen for storing the icon of the new application, the mobile terminal will record and read the sequence number of the screen with free space sufficient for storing the icon of the new application and any class of applications contained in the screen with the sequence number. 
         [0126]    In Step S 605 , the sequence number of the screen with free space sufficient for storing the icon of the new application, and a class of applications contained in the screen with the sequence number, are displayed. 
         [0127]    In an embodiment, the mobile terminal displays on a current screen the sequence number of the screen with free space sufficient for storing the icon of the new application and a class of applications contained in the screen with the sequence number, such that a user may select a class for the new application to be installed. 
         [0128]    In Step S 606 , a class of applications to which the new application belongs is selected according to a displayed class of applications, and the new application is installed using the package file. 
         [0129]    In Step S 607 , an icon management message is sent. 
         [0130]    In an embodiment, the icon management message includes the file name of the package for installing the application, the class to which the application belongs, the sequence number of the screen for display the application and an icon management type MsgType of the new application. The class to which the application belongs is that selected when the new application is installed, the MsgType is 1, indicating that during installing a new application, the mobile terminal directly manages display of the icon of the application by class. 
         [0131]    In Step S 608 , a table App_Class is updated according to the icon management message. 
         [0132]    In an embodiment, the managing module of the mobile terminal calls the table App_Class to update a mapping relation between an application and a class of applications according to the icon management message. 
         [0133]    In Step S 609 , the table App_Class is read, and layout of icons of applications belonging to the selected class of applications in display is refreshed. 
         [0134]    In an embodiment, after updating the table App_Class, the mobile terminal reads the table App_Class, and refreshes the layout of icons of applications belonging to the selected class of applications in display, implementing direct management of display of the icon of the new application. 
         [0135]    In Step S 610 , a user is notified that the new application cannot be installed. 
         [0136]    When it is detected that no screen has enough free space for storing the icon of the new application, a notification that the new application cannot be installed is provided in the current screen. 
         [0137]    With the method for application icon management in a mobile terminal according to the disclosure, display of the icon of a new application by class can be managed directly by setting a class to which the new application belongs during installation of the new application, thereby saving any icon display management after the new application is installed.
