I think you don't understand what "focus" means on Android; it's when a user selects that View, for example when they select an EditText by pressing on it, or they use the keyboard to select a button. When a ViewFlipper switches Views, it does not gain or lose focus.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
