Set Button Visibility

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

Button button1=(Button)findViewById(R.id.button1);
button1.setVisiblity(View.Visible);

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

If you are Using C# you can use 

 button1.Visibility = ViewStates.Visible;

I had the same problem originally.

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.

the View.Visible should be in UpperCase , so try this : 

button1.setVisibility(View.VISIBLE);

and if you aren't in the Activity and you want to change the Visibility , you should pass the Context of the Activity to that class in order to implement the method Acitivity.runOnUIThread(new Runnable());

Steve,

Have you tried View.VISIBLE make sure the VISIBLE is in all caps.
