Android 嵌套GridView，ListView只显示一行的解决办法

public class MyListView extends ListView {

    public MyListView(Context context) {
        // TODO Auto-generated method stub
        super(context);
    }

    public MyListView(Context context, AttributeSet attrs) {
        // TODO Auto-generated method stub
        super(context, attrs);
    }

    public MyListView(Context context, AttributeSet attrs, int defStyle) {
        // TODO Auto-generated method stub
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // TODO Auto-generated method stub
        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
                MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);
    }
}

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); 
        } 
}
