ListView嵌套GridView数据显示不完整解决方案

此问题主要是由于GridView都是可滑动的控件，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);         } }
