ScrollView中嵌入ListView，GridView冲突的解决（让ListView全显示出来）

ScrollView中嵌入原生ListView或GridView，会出现ListView，GridView显示不全的问题。

解决方法：重新构造一个ListView或GridView，重写OnMeasure()方法：

// ListView

 1 import android.widget.ListView;
 2
 3 public class MyListView extends ListView{
 4
 5     public MyListView(android.content.Context context,android.util.AttributeSet attrs){
 6         super(context, attrs);
 7     }
 8
 9     public void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
10     {
11         int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
12                 MeasureSpec.AT_MOST);
13         super.onMeasure(widthMeasureSpec, expandSpec);
14
15     }
16
17 } 

//GridView

 1 public class MyGridView extends GridView {
 2
 3     public MyGridView(Context context) {
 4         super(context);
 5         // TODO Auto-generated constructor stub
 6     }
 7
 8     public MyGridView(Context context, AttributeSet attrs) {
 9         super(context, attrs);
10         // TODO Auto-generated constructor stub
11     }
12
13     public MyGridView(Context context, AttributeSet attrs, int defStyle) {
14         super(context, attrs, defStyle);
15         // TODO Auto-generated constructor stub
16     }
17
18     @Override
19     protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
20         // TODO Auto-generated method stub
21
22         int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,MeasureSpec.AT_MOST);
23
24         super.onMeasure(widthMeasureSpec, expandSpec);
25     }
