No. 13/662,463, filed on Oct. 27, 2012, which is a continuation of International Application No. PCT/CN2011/073430, filed on Apr. 28, 2011, which claims priority to Chinese Patent Application No. 201010166490.4, filed on Apr. 28, 2010, all of which are hereby incorporated by reference in their entireties. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for adding an icon to an interface of an Android system, and a mobile terminal. 
       BACKGROUND OF THE INVENTION 
       [0003]    At present, taking a device installed with an Android system as a representative, more and more handheld touch-screen terminal devices provide large-space Home interfaces for users, and therefore, the users are allowed to place, according to their habits and under a precondition that there is space on a current screen, icons of frequently used favorite programs, widgets, controls, folders and so on to the Home interfaces of the devices, resembling shortcuts on a computer desktop, which greatly facilitates searching for a particular application program by the users when functions of handheld devices become increasingly powerful nowadays. 
         [0004]    During a process of implementing embodiments of the present invention, the inventor finds that the prior art has the following technical problems: If there is no space for placement on the current screen, an icon cannot be added, and a user is required to manually release space for placement, which is inconvenient for the user to operate; in addition, in the prior art, when an icon is to be added to the Home interface, it must be ensured that there are enough space on the current screen, so that the icon can be added; if there is no enough space, a series of operations of selecting an icon to be added by the user previously are invalid, and need to be performed again. As a result, a capability of intelligent interaction between a mobile phone using an Android system and a user is greatly reduced. 
       SUMMARY OF THE INVENTION 
       [0005]    In view of the foregoing problems, an embodiment of the present invention provides a method for adding an icon to an interface of an Android system, where the Android system has N interfaces, and the method includes: 
         [0006]    a. obtaining add command information; 
         [0007]    b. obtaining, according to the add command information, space information of an icon to be added; 
         [0008]    c. obtaining remaining space information of an M th  interface according to the add command information; 
         [0009]    d. judging whether the space information of the icon to be added is greater than the remaining space information of the M th  interface; if yes, executing step e; if no, executing step f; 
         [0010]    e. judging whether the M th  interface is a last interface to be judged; if yes, executing step g; if no, assigning M+1 to M and returning to step c; 
         [0011]    f. adding the icon to the interface, and the process ends; and 
         [0012]    g. establishing another interface, adding the icon to the newly established interface, and the process ends; 
         [0013]    where, M and N are natural numbers, and 1≦M≦N.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
       [0028]    The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings. Evidently, the embodiments to be described are merely part of rather than all of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. 
       Embodiment 1 
       [0029]    Taking a mobile phone using an Android system with 2 interfaces as an example, Embodiment 1 of the present invention provides a method for adding an icon to an interface of an Android system. Referring to  FIG. 1 , the method specifically includes: 
         [0030]    Step  101 : Obtain add command information, where the add command information is command information generated by a mobile terminal system due to a relevant operation of a user when the user needs to move an icon of a certain application program. For example, in a mobile terminal (such as a PC, PDA, and mobile phone) installed with an Android system, when the user presses an icon of a photographing application program, the mobile terminal can obtain the add command information, and determine that the user needs to perform a corresponding add operation on the icon. 
         [0031]    Step  102 : Obtain, according to the add command information, space information of an icon to be added and remaining space information of a current interface. 
         [0032]    The icon mentioned in the embodiment of the present invention specifically refers to icons that are capable of representing visibility or touchability of various application programs, such as a shortcut (shortcut), widget (Widget), folder, sticker, and bookmark. After obtaining the add command information, the mobile terminal obtains, according to the add command information, the space information of the icon to be added. The space information may be two-dimensional plane information, and may also be three-dimensional information. For example, the mobile terminal may obtain an icon with space information being 2×2 square units (such as centimeters). Meanwhile, the mobile terminal may obtain the remaining space information of the current interface. Because the icon to be added needs to be added to the current interface, the mobile terminal needs to determine how much space is left on the current interface. For example, the mobile terminal determines the remaining space information through a grid parameter established by the system itself and information of space that has been occupied by application program icons. 
         [0033]    Step  103 : Judge whether the space information of the icon to be added is greater than the remaining space information of the current interface; if yes, execute step  104 ; if no, execute step  105 . 
         [0034]    For example, the space information of the icon to be added is 2×2 square units, and the remaining space information is 3×2 square units; this square unit takes a horizontal axis—X axis and a longitudinal axis—Y axis of a Cartesian coordinate system as a reference system. The mobile terminal judges that 2&lt;3 and 2≦2, which indicates that the space information of the icon to be added is smaller than or equal to the remaining space information of the current interface. Therefore, the mobile terminal adds the icon to the current interface. Certainly, the space information mentioned in the example is plane information; in the embodiment of the present invention, the space information of the icon and the remaining space information may also be three-dimensional space information. For example, the space information of the icon to be added is 2×2×2 cubic units, and the remaining space information is 3×2×4 cubic units; the mobile terminal judges that 2&lt;3, 2≦2, and 2&lt;4, which indicates that the space information of the icon to be added is smaller than or equal to the remaining space information of the current interface. Therefore, the mobile terminal adds the icon to the current interface; otherwise, the mobile terminal searches for a next interface, and judges whether the next interface has enough remaining space information for adding the icon. 
         [0035]    Step  104 : Switch to a second interface, obtain remaining space information of the second interface, and execute step  106 . 
         [0036]    Step  105 : Add the icon to the current interface, and the process ends. 
         [0037]    Step  106 : Judge whether the space information of the icon to be added is greater than the remaining space information of the second interface; if yes, execute step  107 ; if no, execute step  105 . 
         [0038]    Step  107 : Establish a third interface, add the icon to the third interface, and the process ends. 
         [0039]    In Embodiment 1 of the present invention, whether to add the icon to the current interface is determined by judging whether the space information of the icon to be added is smaller than or equal to remaining space information of the current interface, thereby solving a technical problem that a user is required to determine again and again whether there is enough space before adding a icon in an Android device at present, greatly improving a capability of intelligent interaction between the mobile phone using the Android system and the user, and providing a friendly and human-centered operating experience for the user, so that the user has a good experience from visual and ease of use perspectives during an operation. 
       Embodiment 2 
       [0040]    In Embodiment 1, the mobile terminal using the Android system with 2 interfaces is taken as an example for illustration; Embodiment 2 of the present invention is described specifically below by using an Android system with N interfaces. Referring to  FIG. 2 , Embodiment 2 of the present invention provides a method for adding an icon to an interface of an Android system, and the method specifically includes: 
         [0041]    Step  201 : Obtain add command information, where the add command information is command information generated by a mobile terminal system due to a relevant operation of a user when the user needs to move an icon of a certain application program. For example, in a mobile terminal (such as a PC, PDA, and mobile phone) installed with an Android system, when the user presses an icon of a photographing application program, the mobile terminal can obtain the add command information, and determine that the user needs to perform a corresponding add operation on the icon. 
         [0042]    Step  202 : Obtain, according to the add command information, space information of an icon to be added. 
         [0043]    Step  203 : Obtain remaining space information of an M th  interface according to the add command information. 
         [0044]    The icon mentioned in the embodiment of the present invention specifically refers to icons that are capable of representing visibility or touchability of various application programs, such as a shortcut (shortcut), widget (Widget), folder, sticker, and bookmark. After obtaining the add command information, the mobile terminal obtains, according to the add command information, the space information of the icon to be added. The space information may be two-dimensional plane information, and may also be three-dimensional information. For example, the mobile terminal may obtain an icon with space information being 2×2 square units (such as centimeters). Meanwhile, the mobile terminal may obtain remaining space information of a current interface. Because the icon to be added needs to be added to the current interface, the mobile terminal needs to determine how much space is left on the current interface. For example, the mobile terminal determines the remaining space information through a grid parameter established by the system itself and information of space that has been occupied by application program icons. 
         [0045]    Step  204 : Judge whether the space information of the icon to be added is greater than the remaining space information of the M th  interface; if yes, execute step  205 ; if no, execute step  206 . 
         [0046]    Step  205 : Judge whether the M th  interface is a last interface to be judged; if yes, execute step  207 ; if no, assign M+1 to M, and return to step  203 . 
         [0047]    Step  206 : Add the icon to the interface, and the process ends. 
         [0048]    Step  207 : Establish another interface, add the icon to the newly established interface, and the process ends. 
         [0049]    M and N are natural numbers, and 1≦M≦N. 
         [0050]    The following takes a mobile terminal using an Android system with 3 interfaces as an example to describe the foregoing process in detail. A terminal user performs an operation on a corresponding icon; the mobile terminal obtains add command information, and obtains, according to the command information, space information of the icon and remaining space information of a current interface (which may be called a first interface). Then, judge whether the space information of the icon is greater than the remaining space information of the current first interface; if no, add the icon to the current first interface directly; if yes, judge whether the current first interface is a last interface to be judged. An interface to be judged is obtained through a calculation according to interfaces of the system and an interface that has been judged; in the embodiment, because in the judging step, only the first interface is judged, and there are 2 interfaces which are not judged yet, the current first interface is not the last interface to be judged. Therefore, judge a second interface, which is judging whether the space information of the icon is greater than remaining space information of the second interface; if no, add the icon to the second interface directly; if yes, judge whether the second interface is the last interface to be judged. In the embodiment, because in the judging step, only the first interface and the second interface are judged, and there is a third interface which is not judged yet, the second interface is not the last interface to be judged. Therefore, judge the third interface, which is judging whether the space information of the icon is greater than remaining space information of the third interface; if no, add the icon to the third interface directly; if yes, judge whether the third interface is the last interface to be judged. In the embodiment of the present invention, the third interface is the last interface to be judged, which indicates that none of the three interfaces of the system has enough remaining space information for adding and placing the icon. In this case, the system establishes a new interface—which is called a fourth interface. The fourth interface is newly established, and no application program icon is placed on the interface. Therefore, remaining space information of the interface is whole space of the interface, and the icon may be added to the fourth interface. It may be understandable that, in the embodiment of the present invention, the number of interfaces possessed by the mobile terminal using the Android system is not limited to 3, and may also be multiple, and an operation of adding an application program icon to an interface may also be performed according to the foregoing method process. 
         [0051]    Optionally, after step  206 , the method further includes: 
         [0052]    Step  2061 : After the icon is added, sort all icons on the current interface according to use frequency of the icons. There may be icons of multiple application programs placed on an interface to which the icon is added. The user sorts and then places these icons and the newly added icon, so that an icon of a most frequently used application program may be placed at a most eye-catching or top position, which facilitates an operation of the user. 
         [0053]    In the embodiment of the present invention, whether to add the icon to the current interface is determined by judging whether the space information of the icon to be added is smaller than or equal to remaining space information of the current interface, thereby solving a technical problem that a user is required to determine again and again whether there is enough space before adding a icon in an Android device at present, greatly improving a capability of intelligent interaction between a mobile phone using an Android system and the user, and providing a friendly and human-centered operating experience for the user, so that the user has a good experience from visual and ease of use perspectives during an operation.
