EDIT: For example in android I have 10 buttons (3 for action bar, 7 for every day of the week so I can quickly choose some day of the week and get relevant information and so on, doesn't really matter what the application is about) and only this "type of code" needs ~100 lines of code (per button I need at least 10 lines of code to initialize it and set up a onClick listener), is there a way to shrink this down a bit? However if you insist on having a small and easy to maintain function, you can move anonymous inner classes outside of this method and give their own names. ;), +1 i found myself doing the same..its easy to see all code at once.:).
