java.lang.IllegalStateException: ImageView no longer exists. You should not use this PhotoViewAttacher any more.

这个错误今天碰到了，下面是解决方法，直接上代码

在PhotoViewAttacher 文件中更改cleanup方法

发现可行

 1     /* 
 2          * @SuppressWarnings("deprecation")  
 3          * public final void cleanup() {  
 4          *      if (null!= mImageView) { 
 5          *          mImageView.get().getViewTreeObserver().removeGlobalOnLayoutListener(this);  
 6          *      }  
 7          *      mViewTreeObserver = null; 
 8          *  
 9          * // Clear  
10          *      listeners too mMatrixChangeListener = null;
