Android – the onplaceselectedlistener of supportplaceautocompletefragment is not triggered inside the viewpager

My application has an activity with viewpager and four fragments. In one fragment, I added a Google supportplace autocompletefragment and

 public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.area_swipe_fragment, container, false);



    SupportPlaceAutocompleteFragment autocompleteFragment = (SupportPlaceAutocompleteFragment)
            getChildFragmentManager().findFragmentById(R.id.place_autocomplete_fragment);

    autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
        @Override
        public void onPlaceSelected(Place place) {
            Toast.makeText(ctx, "do something", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void one rror(Status status) {
        }
    });






    return view;
}

My problem is that onplaceselectedlistener will never be triggered, and the results of the selected location cannot be obtained. Instead, onactivityresults() in the second fragment will be triggered. I try to use onactivityresults() in the first fragment, but it will not be triggered. Please always execute in the second fragment

Any ideas?

resolvent:

Start with the docs:

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

Maybe that's the solution
