memory code android

hi

I'm working on desarrolllo a survey where each question has different types of responses .... then I have a button at the end of the survey that saves all the results in a table.

I wanted to see if this well-written, if the code is well written and if you follow the good practice to not consume much memory when compiling.

Suggestions are welcomed, thanks

Working with these specifications:

titanium sdk 3.3.0 for android 4.1

This file is the window that contains all the elements.
