 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

    /* 
         * @SuppressWarnings("deprecation")  
         * public final void cleanup() {  
         *      if (null!= mImageView) { 
         *          mImageView.get().getViewTreeObserver().removeGlobalOnLayoutListener(this);  
         *      }  
         *      mViewTreeObserver = null; 
         *  
         * // Clear  
         *      listeners too mMatrixChangeListener = null;  
         *      mPhotoTapListener = null; 
         *      mViewTapListener = null; 
         *  
         * // Finally, clear ImageView
