Android Fragment TextView setText from main activity

Question

I got a MainActivity and it has 3 fragments. One of those fragments got one TextView. How Can I manipulate that TextView from MainActivity?

On my MainActivity I have a TabLayout with that 3 fragments. I got data from database in MainActivity and I would like to change the textview that is on fragment 1 with that data I got.

Thank you.

I am suggest you to create some method in one of your Fragment example : In Fragment One create/ add this method :

public void Test(String jajal_disek) {
    Toast.makeText(getActivity().getApplicationContext(), jajal_disek,Toast.LENGTH_SHORT).show();
    ABC.setText(jajal_disek); //example your textview name ABC
}

and then in MainActivity call that's method inside FragmentOne like this :

FragmentOne fragment = (FragmentOne) getSupportFragmentManager().findFragmentById(R.id.container_body);                
            fragment.Test("StackOverFlow");

Hope this will help you, be great if you write source code to identified problems
