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
          *      mImageView = null; }
          */
