Set Button Visibility

I added a button in layout and obtained its reference in the activity:

Button button1=(Button)findViewById(;

Program crashes with this code. How do I set its visibility correctly?


Whats the error? it should be View.VISIBLE (uppercase).

If you have a null pointer exception at that point, its probably because its not finding the view in your layout.
