ListView中嵌套GridView关于GridView的高度显示问题

经常要在ScrollView中嵌入ListView，网上方法一大堆，但都比较繁琐。 
本人认为比较好的办法如下： 

 import android.widget.ListView;

 /**
  * ScrollView中嵌入ListView,让ListView全显示出来
  * @author reyo
  *
  */
 public class MyListView extends ListView{

     public MyListView(android.content.Context context,android.util.AttributeSet attrs){
         super(context, attrs);
     }

     /**
      * 设置不滚动
      */
     public void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
     {
         int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
                 MeasureSpec.AT_MOST);
         super.onMeasure(widthMeasureSpec, expandSpec);

     }

 }

继承ListView，重写onMeasure即可。 

同样，当ListView中嵌套一个GridView时，也需要重写一下GridView，否则只会显示一行GridView的数据。 

 import android.widget.GridView;

 public class MyGridView extends GridView {
     public MyGridView(android.content.Context context,
             android.util.AttributeSet attrs) {
         super(context, attrs);
     }

     /**
      * 设置不滚动
      */
     public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
         int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
                 MeasureSpec.AT_MOST);
         super.onMeasure(widthMeasureSpec, expandSpec);

     }

 }
