PhotoView单击事件

PhotoView是一个很好用的图片缩放库，github地址为https://github.com/chrisbanes/PhotoView

为PhotoView添加单击事件的方法如下

            PhotoView photoView = new PhotoView(container.getContext());
            photoView.setBackgroundColor(Color.BLACK);
            final PhotoViewAttacher attacher = new PhotoViewAttacher(photoView);
          
            attacher.setOnPhotoTapListener(new PhotoViewAttacher.OnPhotoTapListener() {
                @Override
                public void onPhotoTap(View view, float x, float y) {
                //图片区域内单击
                //activity.finish();
                }

                @Override
                public void onOutsidePhotoTap() {
                    //图片区域外单击
                    //activity.finish();
                }
            });
