由于GridView是可滑动的控件，嵌套在ScrollView下时需要重写onMeasure方法。


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); 
    } 
}
