public class MyGridView extends GridView {  
    private boolean haveScrollbar = true;  
    public MyGridView(Context context) {  
        super(context);  
    }  
    public MyGridView(Context context, AttributeSet attrs) {  
        super(context, attrs);  
    }  
    public MyGridView(Context context, AttributeSet attrs, int defStyle) {  
        super(context, attrs, defStyle);  
    }  
    /** 
* Set whether there is a ScrollBar, and when it is to be displayed in the ScollView, it should be set to false. Default is true
     *  
     * @param haveScrollbars 
     */  
    public void setHaveScrollbar(boolean haveScrollbar) {  
        = haveScrollbar;  
    }  
    @Override  
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {  
        if (haveScrollbars == false) {  
            int expandSpec = (Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);  
            (widthMeasureSpec, expandSpec);  
        } else {  
            (widthMeasureSpec, heightMeasureSpec);  
        }
