I have done this just now. I only have the emulator for testing right now. Should click and drag with the mouse move the image? It doesn't. However, when I double-click, it zooms the image. – user2602079 Jan 05 '14 at 23:02
It also appears that zooming the image does not resize the image. So a lot of the image gets cropped out when it enlarges (From my double tap testing). Do you know any libraries to resize the image on pinch? I cannot find one. They all say pinch zoom. Not pinch resize/scale. Thanks – user2602079 Jan 05 '14 at 23:45
Can i save the zoomed image using this library? – Chetan Gaikwad May 08 '15 at 10:55

You can find below a link to a class created by Jason Polites that will allow you to handle pinch zooms on custom ImageViews: https://github.com/jasonpolites/gesture-imageview.

Just include this package into your application and then you will be able to use a custom GestureImaveView in your XML files:

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:gesture-image="http://schemas.polites.com/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

<com.polites.android.GestureImageView
    android:id="@+id/image"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:src="@drawable/image"
    gesture-image:min-scale="0.1"
    gesture-image:max-scale="10.0"
    gesture-image:strict="false"/>

This class handles pinch zooms, but also double taps.

Try this gesture library it comes with an out-of-the-box pan zoom mode: https://bitbucket.org/warwick/hacergestov3 — user2288580, Apr 24 '18 at 12:35
