Chaneg your method like this..then it will work..

@Override
public void onClick(View view)
{
LayoutParams params = view.getLayoutParams();
     if (!large)
        {
            params.height = 2 * view.getHeight();     
        } else {
            params.height = view.getHeight()/2;
        }
        large = !large;
        view.setLayoutParams(params);
}
