Android Question Scalling view like WebView by fingers

[Sergio Luchi]

Hello everyone!
The webview has the ability to change the size of the visible content with gestures. I found how to do this with a web page or database table. Similar soluthin I found for images.

As I wrote, you should learn the code in ZoomImageView. It implements the gestures and the view resizing. You need to change the resizing to handle various layouts.
