android ，点击title的ImageView弹出PopupWindow【安卓进化七】
一、曾经做过一个项目，用的大概就是这种布局，title布局，title右边是ImageView，点击每一个图标，弹出PopupWin，点击其他按钮PopupWin就在原地消失。这个效果还很不错的，我挺喜欢的，所以抽空把它写了出来。现在将代码给大家提供一下，希望能给大家一些提示。先看截图：
点击MP3这个图标：点击PopupWin苹果MP3这列弹出Toast：
点击PopupWin中魅族这列弹出Toast： 点击短信这个图标：
点击新建这个图标： 点击音乐这个图标：
点击电话这个图标：点击作者这个图标：
点击PopupWin第一列弹出Toast：点击PopupWin第二列弹出Toast：
说明：每一个popupwin里面我都写了点击事件，就是弹一个toast，目前我就截图截了四张，给大家演示一下！
二：布局文件
1、activity_title.xml布局文件代码：
2、new_file.xml
三、MainActivity类，java类实现以上功能：

四、设置PopupWin,设置进入和退出的的动画：
在res目录下建anim文件夹，在里面加入布局文件：
1、popup_enter.xml:
2、ppup_exit.xml
五、在Values加入一个style.xml样式的xml文件：
六、看一下，drawable的图片，这个大家可以根据自己的要求自己在网上找图片，图片我没有上传,希望大家理解，有需要的可以留个邮箱，我可以把整个项目发给你。
1、里面有个word_view.xml:
