支持如微博那般的长图么

4.0-4.0.4对应的api level 14 he 15还有较高的占有率，我只好源码拿来使用了

长按事件弹出框以后页面就销毁了怎么解决呢？求解

viewpager里的图片不能双指缩放

在viewPager中，先滑动到第二张图片，再返回第一张时，此时直接下拉是不会有拖拽效果的，但可以看到图片会稍微居中移动了一下，然后第二次按住拖动就可以了触发拖拽效果了

修改了两个方法里默认0的参数，改为动态的但效果没有出现，而且出现了显示错乱的情况。

RT

1 DragPhotoView 的 dispatchTouchEvent 方法 ACTION_MOVE 里面处理得有问题有时候左右移动会响应 Y 轴 onActionMove 事件 有时候又交给 viewpager 去处理了
2 下滑到一部分松手会出现另外一个问题DragPhotoView 的 dispatchTouchEvent 方法 MotionEvent.ACTION_UP 里面可能同时触发 onExit onTap 两个回调

代码还在看，目前只是发现了问题没能解决不好意思。如果能提供一些思路不胜感激
，这个库 star 这么多还是值得好好维护。

超长图显示不全，放大几倍后，无法继续放大 ，有没有值可以直接控制无限放大的？

左右滑动的时候容易误触下拖退出

在ViewPager中图片左滑（不是下滑），这时候应该是响应ViewPager滑动事件，而不是对图片进行缩放

library version: 1.0.1
1、有些图片显示不出来，一片漆黑。
2、有些图片缩放的比例太大，没有适配图片尺寸来显示
