I have a problem here which is as follows, I have an Activity (extending from FragmentActivity ) that has a ViewPager using SectionsPagerAdapter as an adapter.
I can create as many pages as I need and pass data to them, my problem is being able to capture the data recorded in the fields.
For example, when switching pages, I would like to record what was typed in the fields of the current screen, before going to Screen 2.
Or through Button , click and already record what was typed.
I do not know how to get the EditText of pages.
Look at the code:
