14,483 PointsThe button variable has been initialised as protected Button mExterminateButton;
But you have written it as MExterminateButtoncast -- with a capital M in the beginning. Java is case sensitive.
Change it to mExterminateButtoncast.findViewById(button1); ... though this statement is wrong
Other issue is the question clearly says cast the generic view. If you haven't watched the beginner tutorials as yet I would suggest do that. All these basics has been covered there.
Also findViewById is not a method of the Button class. But rather standalone in a sense that helps find the view through its id.
So basically the statement should be
mExterminateButtoncast = (cast_to_button) findViewById(name_of_button_id);
Hope this helps
