There are dozens of this kind of threads, but i couldnt find and solution for my problem (at least working one).
So i have 3 fragments in my viewpager, my last (3rd) fragment is basically a friendlist, i also have a button with which i open a new fragment, where i handle search/request etc. In that fragment i have "back button", i get back to my "3rd" fragment in a viewpager with getFragmentManager().popBackStack(). How can i pass boolean value or something back to the "3rd" fragment?
I tried with manually calling onPause and onResume methods of the 3rd fragment, but then my list is empty. Also no methods of the 3rd fragment is called when i popbackstack.
This is my code
3rd fragment
This is how i open new fragment
ImageButton friendsButton = (ImageButton) v.findViewById(R.id.friendsButton);
friendsButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
SearchActivity configDetailSectionFragment = new SearchActivity();
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.add(R.id.item_detail_container, configDetailSectionFragment);
transaction.addToBackStack(null);
transaction.commit();
}
});
and this is how i get back to the 3rd fragment
ImageButton backButton=(ImageButton)rootView.findViewById(R.id.backButton);
backButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
getFragmentManager().popBackStack();
} });
My methods for filling exlistview work fine, just no methods are called after popbackstack, so i could update my list.
What should i change and when and where should i call listadapter.notifyDataSetChanged()?
