I needed that when I entered the Fragment he executed this method Verifcar() in main Activity to check the condition and not show the RecyclerView.

Mainactivity.Java

public void Verificar(){
            if(pref.getBoolean(Constants.IS_LOGGED_IN,false)){

                recyclerView.setVisibility (View.VISIBLE);
    }else {

                recyclerView.setVisibility (View.INVISIBLE);
    }

}

You can call your Activity method from within Fragment using:

((SuaActivity)getActivity()).seuMetodoPublico();

If you have problems with cast of Activity, you can use:

Activity activity = getActivity();

if (activity instanceof SuaActivity){
 ((SuaActivity) activity).seuMetodoPublico();
}

  • Thank you for your suggestion, but I would like you to call this method by being called the Fragment in this case where I should place the method in the body of the Fragment ?

  • I recommend a override in your Fragment’s onActivityCreated() method. So it would only be called after the Views initialization.
