Question

Can we use scale gesture detector for pinch zoom in Android?

Answer 1

ScaleGestureDetector is available starting in Android 2.2 (aka Froyo, API level 8). See: http://android-developers.blogspot.com/2010/06/making-sense-of-multitouch.html

In 2.0/2.1, you don't have ScaleGestureDetector, but you can provide pinch-to-zoom using the ZDNet blog entry by Ed Burnette that Pieter888 linked to above: http://www.zdnet.com/blog/burnette/how-to-use-multi-touch-in-android-2-part-6-implementing-the-pinch-zoom-gesture/1847
