onActivityResult never called in my nested fragment

Question

I have many nested fragments.

• Activity A
  • MainFragment (in a FrameLayout)
    • Fragment A (in a FrameLayout in MainFragment)
    • Fragment B (in a FrameLayout in MainFragment)
      • Fragment C (in a ViewPager in Fragment B)
      • Fragment D (in a ViewPager in Fragment B) <--- this is where I want to catch onActivityResult

This is how I start activity for result:

startActivityForResult(Intent.createChooser(intent, "Title"), FILE_PICK);

I don't have onActivityResult overriden anywhere else. I tried to call it in Activity A and it got called, but then even though I called super, it never came to Fragment D. Also tried to call onActivityResult in MainFragment and it never gets called there either.

Answer 1

The event is going to be received in the activity. To have it in Fragment D you have to propagate it.

On your parent activity override onActivityResult and start calling the onActivityResult of your fragments:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    List<Fragment> fragments = fragmentManager.getFragments();
    if(fragments != null){
        for(Fragment fragment : fragments){
            fragment.onActivityResult(requestCode, resultCode, data);
        }
    }
}

In your parent fragment you have to do the same thing, but remember to use getChildFragmentManager to get the fragment manager of the fragment

    List <Fragment> fragments = getChildFragmentManager().getFragments();
