今天我接着站在了巨人的肩膀上了!因为上次我参考大神利用 Path 实现了点九图效果,附上我上次讲解链接: .这一次,我将完成上次说的实现点击toolbar按钮弹出菜单效果,当然还是利用 Path 来完成这个效果.如果想看巨人的巨作,请点击: ,我此次仅仅是将大神的点九图更换为一个由Path完成的效果而已.

首先,我们还是看下我完成的结果吧!

嘿嘿,和大神的一样哈!是的,我只是改了背景图而已.这样我们就可以随便刷不要UI哥帮忙了,而且那个三角凸起可以 左右位置调整 哦!

首先还是看下MainActivity的布局吧

    
        
             
              
          
     
    复制代码

这个就不说啥了,接着,来重点了,看 Recyclerview 了,因为大神用的是这个控件,那我只是给这个控件换了个衣服!
