Q:
Trying to call a method in my activity from a fragment. I want the fragment to give the method data and to get the data when the method return. I want to achieve similar to call on a static method, but without the use of static because it create problems in the activity.
New to fragments so I need an easy and pedagogic explanation!
Thanks!
A:
From fragment to activty:
((YourActivityClassName)getActivity()).yourPublicMethod();From activity to fragment:
FragmentManager fm = getSupportFragmentManager();//if you added fragment via layout xmlYourFragmentClass fragment =(YourFragmentClass)fm.findFragmentById(R.id.your_fragment_id);
fragment.yourPublicMethod();If you added fragment via code and used a tag string when you added your fragment, use findFragmentByTag instead:
YourFragmentClass fragment =(YourFragmentClass)fm.findFragmentByTag("yourTag");
