public class MyGridView extends GridView{
   public MyGridView(Context context, AttributeSet attrs) { 
      super(context, attrs); 
    } 
   
    public MyGridView(Context context) { 
      super(context); 
    } 
   
    public MyGridView(Context context, AttributeSet attrs, int defStyle) { 
      super(context, attrs, defStyle); 
    } 
   
    @Override 
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
   
      int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE    2, 
          MeasureSpec.AT_MOST); 
      super.onMeasure(widthMeasureSpec, expandSpec); 
    } 
}
