RecyclerView+Glide+PhotoView

"font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">RecyclerView是谷歌最新的代替ListView和GridView一款超赞控件，可以随意变成ListView,GridView,和瀑布流的样式，也许是才出来不久，苦恼的是它的监听事件有点麻烦，需要自己动手重写方法，后面代码里会体现出来。Glide是一款高效图片处理的第三包，比较其他的图片处理第三方包要高效，好用很多，自己可以上网查查了解了解。PhotoView是一款支持放大缩小图片浏览的第三方包，用法都很简单。

先看看效果图：

主界面的瀑布流照片墙：

然后点击某一张图片，进入大图：

然后两点手势缩放图片，最后点击图片，退回到原图

activity代码：

public class RecyclerViewGridImageActivity extends Activity {
    private RecyclerView mRecyclerView;
    private MyRecyclerViewAdapter adapter;

最后带上我的项目要添加的第三方包：

需要下载最新版的glide-3.6.1.jar

需要下载PhotoView第三方源码，然后导入它的library，如上图；
