Android using hand gestures to move and zoom

Question

I have an image that gets created once a button gets clicked; it gets created in the middle of the canvas, as I set it to do so:

if(choosenImage != null) {
     c.drawBitmap(choosenImage, 0, 0, null);
}

I want to move and zoom the image using my hand, like drag to to, move it, etc.

How can I do that ? And is that related to onTouchListener?

May this two links help you: Zoom: http://stackoverflow.com/questions/6650398/android-imageview-zoom-in-and-zoom-out Move: http://stackoverflow.com/questions/5743328/android-image-in-canvas-with-touch-events/5747233#5747233 — Bruno Bieri, Aug 13 '12 at 05:21
