PinchToZoom

Android's ImageView pinch-to-zoom made easy

Sample app

Get it

Add this line to your build.gradle's dependencies:

compile 'com.bogdwellers:pinchtozoom:0.1'

Overview

PinchToZoom for Android is a simple yet feature complete library for adding pinch-to-zoom functionality to an ImageView. It has sleek easing animations that make it stand out in quality and ease of use.

Features

  • Pinch-to-zoom
  • Double-tap to quickly zoom-in and out
  • Drag while zoomed in
  • Animated drag & zoom release easing
  • Does not extend the ImageView class so is usable with custom ImageView implementations
  • Fully customizable

Integrate

Adding pinch-to-zoom functionality to your ImageView is easy as this:

ImageView imageView = (ImageView) view.findViewById(R.id.image);
imageView.setOnTouchListener(new ImageMatrixTouchHandler(view.getContext()));

Customization

The ImageMatrixTouchHandler class has multiple getter/setter methods that allow for changing the behavior and animation settings.
