PhotoView点击事件处理

PhotoView是一个很棒的开源组件，可以伸缩图片，双击放大，单击返回等一系列常用功能,具体实现如下:

 @Override
    public View instantiateItem(ViewGroup container, int position) {
    PhotoView photoView = new  PhotoView(container.getContext());

    photoView.setOnPhotoTapListener(new PhotoViewAttacher.OnPhotoTapListener() {
        @Override
        public void onPhotoTap(View view, float x, float y) {
            imageBrowser.finish();
            imageBrowser.overridePendingTransition(0, R.anim.zoom_exit);
        }
    });
 }
