class ImageViewZoom public methods: setImage(Bitmap) - Bitmap which you want to show in view(layout) setImage(Bitmap bitmap, int widthOfParent) - you can set maximum width(in pixels) of parent if you want. But in most cases above will be enough. Extend class and override method protected void onImageClick(float posX, float posY) to add custom ontouchhandler Look at example for more.
