</android.support.design.widget.AppBarLayout>

<FrameLayout

CODE FragmentManager fragmentManager = ((FragmentActivity) context).getSupportFragmentManager(); FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); fragmentTransaction.setCustomAnimations(android.R.anim.fade_in, android.R.anim.fade_out); fragmentTransaction.replace(R.id.frame_container, new SavedReq_frag(),MYTAG); fragmentTransaction.addToBackStack(null); fragmentTransaction.commit();
