你显示图片比较大么？为什么需要我这个。
简单点的话，你可以RecyclerView实现，getCount 值int最大值，设置position在中间，就达到了类似可以无限的效果
麻烦点的话，就自己自定义View，View直接屏幕大，实现好像ScrollView的手势，然后再通过滚动的位置去计算显示的图片区域

是很大的全景图，我最开始也是直接自定义View，然后根据手势使用BitmapRegionDecoder去截取不同的图片显示，但是很卡，性能很差。

你的库在性能和缓存方面给了我很大的提示，所以想借鉴图片加载的方式。

只是在滑动到边界位置如何计算并显示图片块，卡住了，不知道怎么处理。。。

我不明白的是为什么是添加两个LargeImageView
你全景图到底要显示几个啊

就一个啊，但是滑到边界还不知怎么处理，领导又要看效果，所以先用了两个LongImageView2来实现循环的效果。

就是滑到3/4的位置时，将前面的移除，然后再后面添加一个，权宜的做法。

现在想找更好的做法。

我上面说的RecyclerView方案不行么？

如果用RecyclerView的话，是先把图片裁成一些块，然后填充到item中吗？

一个LongImageView2作为一个item啊
一个图片用一个LongImageView2显示
