Pinch and double tap zoom for NetworkImageView

Question

I am trying to implement pinch zoom and double tap feature on NetworkImageView inside a ViewPager. I referred to this tutorial: http://www.androidhive.info/2013/09/android-fullscreen-image-slider-with-swipe-and-pinch-zoom-gestures/

Images are loading fine using Volley and NetworkImageView. Even the pinch zoom is working but its not smooth at all. After zooming, the current image is zooming under the next and previous image in ViewPager. Also, the previous image zoom is not resetting.

I tried using Mike Ortiz's new version of TouchImageView code but images are not loading for NetworkImageView.

So,

Do I need to use new version of TouchImageView for better pinch zoom experience and enabling double tap?
If yes, will it work for NetworkImageView?
How to fix the issue of zooming under next and previous image?
How to reset the zoom of previous image?

Thanks.

Any help will be appreciated? – johnk1 Oct 03 '14 at 17:32 — johnk1, Oct 03 '14 at 17:32
Nopes. But I used imageView along with Volley. – johnk1 Oct 16 '14 at 18:26 — johnk1, Oct 16 '14 at 18:26

Use this NetworkImageView instead of the NetworkImageView from volley: https://github.com/geeknizer/Volley-Flickr-Gson-List-GridView-example/blob/master/src/com/androidng/flickr/view/NetworkImageView.java

It is the same but with the corrections to work!

This works flawlessly if you assign a src in xml for this NetworkImageView. – Rishabh Srivastava Jan 07 '15 at 09:10

It is doable!
I have used the codebase from android imageview zoom. All you need to do is in ImageViewTouchBase.java you need to replace class extension by NetworkImageView. Works like charm.
You might want to alter the onDoubleTap function to have just one level zoom in/out feature.

Could you elaborate on how you did this to help others out there who are trying to load network images but also would like the features of TouchImageView. – startoftext Nov 10 '14 at 19:38
hello @johnk1 can you please tell how did you apply zoom on network imageview? – TechChain Apr 27 '15 at 06:12
I think TouchImageView is there in Picasso http://square.github.io/picasso/ library – Rakesh Yadav Feb 11 '17 at 08:52
