How to view a big picture by dragging on Android? Just like we do on Google Maps

I've being trying this all ni开发者_如何学运维ght through. Is there any good solution to do this? Having a sample code is better!

I will answer my own question, after a loooong time.

I finally found a solution, just use the WebView, to load the image in the browser inside the WebView, Android then did everything for me!
