Add Fragment Into Fragment?

I create an activity container where I added an fragment using : FragmentTransaction ft = getFragmentManager().beginTransaction(); ft.replace(R.id.simple_fragment, myFragment);

Solution 1:

Access the Activity that is hosting the Fragment and ask it to replace your Fragment.

Something like

((MyActivity) getActivity()).goToOtherFragment();

Solution 2:

in your 1A fragment you have to give an id to the parent view that will hold the 1B fragment example

<FrameLayout android:id="@+id/content"/>

then you have to add the new 1B fragment to 1A

 Fragment1B fragment1B = new Fragment1B();
 FragmentTransaction transaction=getFragmentManager().beginTransaction();     
 transaction.add(R.id.content,fragment1B,"fragment1BTAG");
 transaction.addToBackStack(null);
 transaction.commit();

and some times you need to set the background color of your 1B fragment root view to white , because it load as trasnparent

then in your onBackPressed() you can just use the

FragmentManager fm=getSupportFragmentManager();
fm.popBackStack();
