android中ListView嵌套

如果在ListView中嵌套一个ListView，则需要定义子类ListView的高度。代码如下:

public class MyListView extends ListView {
    
    public  MyListView  (Context context, AttributeSet attrs) {
 
        super(context, attrs);
 
    }
 
    public  MyListView  (Context context) {
 
        super(context);
 
    }
 
    public  MyListView  (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);
 
    }
 
}
