How can I call a method from nested fragment

Question

I have a fragment(this is one tab of my tabhost) "fragA" inside other fragment "fragB" but I need to call one method of "fragB" from "fragA". when I do from an activity, I do this:

FragB detailsFragment=(FragB)getSupportFragmentManager().findFragmentById(R.id.detailFragment);

detailsFragment.consultaWS(convertIntWebService(categoria),"Pdf");

please, help me

Answer 1

I could finally solve it this way, in fragA:

FragB parentFragment = (FragB) getChildFragmentManager()
                                      .findFragmentByTag("detallesFragBusqueda");
if (parentFragment != null) {
    parentFragment.consultaWS("", "AllPdf");
}

Answer 2

Your activity should facilitate all communication between fragments. Just create a method in your Activity that a fragment can call, which will tell another fragment to do something.

Answer 3

If FragA is inside FragB, you can do the same from within your FragA.

 FragB parentFragment = (FragB)getActivity().getSupportFragmentManager().findFragmentById(R.id.detailFragment);
 parentFragment.fragmentBMethod();

Answer 4

Read this http://developer.android.com/training/basics/fragments/communicating.html. This document explains that how can you communicate between Activity and Fragment and also between 2 Fragments

Answer 5

Fragment fragment = getFragmentManager().findFragmentById(R.id.fragment_main_container);
if (fragment != null) {      
       ((TabLayoutFragment)fragment).tabClickDisable();
}
