Answer 1

If you wish to change the ImageView's size, you need to change its layoutParams, as I've demonstrated here. You can also change its scale as of Honeycomb.

However, if you wish to just move a rectangle within the image, which also zooms nicely (like other apps that allow to crop), you can use a library like "cropper" or if you don't need the features there you can use a library like TouchImageView
