Hiding linear layout on runtime in Android

Question

I am having following layout

Answer 1

It looks like you're setting the wrong constants for changing view visibility.

GONE == 8
INVISIBLE == 4
VISIBLE == 0

However, you should never rely on the actual values that Android happened to designate to represent their constants. Instead use the the values defined in the View class: View.VISIBLE, View.INVISIBLE, and View.GONE.

// snip...
if(visibility == View.VISIBLE)
{
    visibility = View.GONE;
}
else
{
    visibility = View.VISIBLE;
}
ll.setVisibility(visibility);

And don't forget to call invalidate() on the view :)

Answer 2

You should use the Constants provided by View

View.INVISBLE, View.VISIBLE, View.GONE

and also invalidate your View
