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.

只是包含这个包到您的应用程序，然后你就可以使用自定义的 GestureImaveView XML文件中的：

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"/>

本类处理捏缩放，而且双水龙头。

This class handles pinch zooms, but also double taps.
