How to create an image with the zoom and pan function?

I created an application that has a small image downloaded from a website URL. I want that when a user clicks on this small image, he will display the image in full screen mode, and also be able to scale and pan this image.

What I did was display an image in WebView with built-in zoom controls, but the result was ugly. (I set the layout for wrap_content, so white areas are not displayed, but this leads to the fact that the image does not dynamically increase).

Any solution? and sorry for my bad english.

The problem is solved! For those who have the same problem, I use this library and it works great! http://blog.sephiroth.it/2011/04/04/imageview-zoom-and-scroll/

Here's a link to the Github ImageViewZoom page .

You can create this from scratch or ... you can use this library:

Take a look at the PinchImageView class

You need to use GestureDetectors. Google has a great interactiveChart sample for this, see https://android.googlesource.com/platform/development/+/master/samples/training/InteractiveChart and http://developer.android.com/training/gestures/scroll. html
