Using the new structure of ExpenseListTotal. Need to be debugged.
Fixed a bug when adding an expense to the list. It must be first added to the database in order to get the correct id, because the id is used lately in the expense list (map) as key.
Updated the screen casts. Created the name for english version and for the spanish version. Added colored background when the user clicks on any row.
Changed the background color when there is not expenses.
Created a method to show an expense to be edited. Clear all the elements related with the clone of the expense.
Added the missing file row_background.xml. Fixed a bug when the application starts and the menu is not ready. Added a bug when there is 2 elements in the list and one of them has been removed.
Fixed an bug when updating the right corner. In the right drawer, use the same text as the main list if there is not expense.
