Answer 1

I also faced fragment overlapping issue.Here is how I solved it -

1) We need to add the first fragment with addToBackStack, so that it is retained in the stack -

FirstFragment firstFragment = new FirstFragment();
getFragmentManager().beginTransaction().add(R.id.fragment_container, firstFragment).addToBackStack("first frag").commit();

2) While adding the second fragment, replace the first fragment rather then adding it.Since the first fragment was already added in the stack, so it will be present when you press back from second fragment -

SecondFragment secondFragment= new SecondFragment();
getFragmentManager().beginTransaction().replace(R.id.fragment_container, secondFragment).addToBackStack("second frag").commit();

3) Here is how back press can be handled, below code should be present in the parent Activity -

 public void onBackPressed(){
    if(getFragmentManager().getBackStackEntryCount() <= 1){
       super.onBackPressed();
    } else {
       getFragmentManager().popBackStack();
    }
 }
