1. 自定义三个View，都是继承ViewGrop，写法如下方法：

public class ViewGroupB extends ViewGroup {
    

    public ViewGroupB( Context context ) {
        super( context );
        
    }
    
    public ViewGroupB( Context context, AttributeSet attrs ) {
        super( context, attrs );
        
    }
    
    public ViewGroupB( Context context, AttributeSet attrs, int defStyle ) {
        super( context, attrs, defStyle );
        
    }
    
    @Override
    protected void onLayout( boolean changed, int l, int t, int r, int b ) {
        
    }
    
    @Override
    public boolean dispatchTouchEvent( MotionEvent ev ) {
        Log.d( "TAG", "dispatchTouchEvent B : " + ev.getAction() );
        return super.dispatchTouchEvent( ev );
    }
    
    @Override
    public boolean onInterceptTouchEvent( MotionEvent ev ) {
        Log.d( "TAG", "onInterceptTouchEvent B : " + ev.getAction() );
        return super.onInterceptTouchEvent( ev );
    }
    
    @Override
    public boolean onTouchEvent( MotionEvent event ) {
        Log.d( "TAG", "onTouchEvent B : " + event.getAction() );
        return super.onTouchEvent( event );
    }
    
}

这样做只是想看看View的点击事件是怎样处理的，没想到这被卡住了，懂得伙伴们帮忙看看，万分感谢。
