Using a view pager

Instead of importing from ViewPagerAndroid import ViewPagerZoom from react-native-image-zoom there is a bug in android view pagers with pinch and zoom.

import {ViewPagerZoom} from 'react-native-image-zoom'
<ViewPagerZoom style={styles.container}>
  <View style={{flex:1, alignItems:'center', justifyContent:'center'}}>
    <Image
      source={{uri:"http://placehold.it/200"}}
      style={{width:width, flex:1,}}
      onTap={()=>{ToastAndroid.show('ON TAP',ToastAndroid.LONG)}}
      onLoad={()=>{
        ToastAndroid.show('onLoad',ToastAndroid.LONG)
      }}
      />
  </View>
  <View style={{flex:1, alignItems:'center', justifyContent:'center'}}>
    <Image
      source={{uri:"http://placehold.it/200"}}
      style={{width:width, flex:1,}}
      onTap={()=>{ToastAndroid.show('ON TAP',ToastAndroid.LONG)}}
      onLoad={()=>{
        ToastAndroid.show('onLoad',ToastAndroid.LONG)
      }}
      />
  </View>
</ViewPagerZoom>

Installation

Installation

Install the npm package react-native-image-zoom. Inside your React Native project, run (example):
In android/settings.gradle

include ':react-native-image-zoom'
project(':react-native-image-zoom').projectDir = file('../node_modules/react-native-image-zoom/android')

NOTE : If you have included other libraries in your project, the include line will contain the other dependencies too.
In android/build.gradle add the jitpack repositories.

allprojects {
    repositories {
        mavenLocal()
        jcenter()
        maven { url "https://jitpack.io" } // <--- add this line
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
    }
}

In android/app/build.gradle, add a dependency to ':react-native-image-zoom'

dependencies {
    compile project(':react-native-image-zoom')
}

Next, you need to change the MainActivity of your app to register ReactImageZoom :

import com.image.zoom.ReactImageZoom; // add this import

public class MainActivity extends ReactActivity {
    //...

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
          new MainReactPackage(),
          new ReactImageZoom() // add this manager
      );
    }
}
