Answer 1

For zoom-able ImageView user Gesture ImageView Library

You can download library from here, it's easy to use. this library provides you zoomable ImageView so use Gesture ImageView instead of Simple ImageView

Answer 2

use android:scaleType="fitxy" . Make sure your image is of higher resolution, otherwise the image will lose its quality. It may also look stretched if it the image doesn't maintain aspect ratio
