android ListView嵌套GridView显示不全问题

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);

}

}
