Listen to device orientation changes in react-native and set preferred orientation on screen to screen basis.

React Native Orientation

Listen to device orientation changes in React Native applications and programmatically set preferred orientation on a per screen basis. Works on both Android and iOS.

Installing

npm install react-native-orientation --save

Linking Native Dependencies

Automatic Linking

react-native link react-native-orientation

Manual Linking

iOS

1. Add node_modules/react-native-orientation/iOS/RCTOrientation.xcodeproj to your xcode project, usually under the Libraries group
2. Add libRCTOrientation.a (from Products under RCTOrientation.xcodeproj) to build target's Linked Frameworks and Libraries list

Android

1. In android/setting.gradle

   ...
   include ':react-native-orientation', ':app'
   project(':react-native-orientation').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-orientation/android')
   

2. In android/app/build.gradle

   ...
   dependencies {
       ...
       compile project(':react-native-orientation')
   }
   

3. Register module in MainApplication.java

   import com.github.yamill.orientation.OrientationPackage;  // <--- import
   
   public class MainApplication extends Application implements ReactApplication {
     ......
   
     @Override
     protected List<ReactPackage> getPackages() {
         return Arrays.<ReactPackage>asList(
             new MainReactPackage(),
             new OrientationPackage()      <------- Add this
         );
     }
   
     ......
   
   }

Configuration

iOS

Add the following to your project's AppDelegate.m:

#import "Orientation.h" // <--- import

@implementation AppDelegate

  // ...

  - (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
    return [Orientation getOrientation];
  }

@end

Android

Implement onConfigurationChanged method in MainActivity.java

    import android.content.Intent; // <--- import
    import android.content.res.Configuration; // <--- import

    public class MainActivity extends ReactActivity {
      ......
      @Override
      public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        Intent intent = new Intent("onConfigurationChanged");
        intent.putExtra("newConfig", newConfig);
        this.sendBroadcast(intent);
    }

      ......

    }

Usage

To use the react-native-orientation package in your codebase, you should use the Orientation module:

import Orientation from 'react-native-orientation';

export default class AppScreen extends Component {
  // ...

  componentWillMount() {
    // The getOrientation method is async. It happens sometimes that
    // you need the orientation at the moment the JS runtime starts running on device.
    // `getInitialOrientation` returns directly because its a constant set at the
    // beginning of the JS runtime.

    const initial = Orientation.getInitialOrientation();
    if (initial === 'PORTRAIT') {
      // do something
    } else {
      // do something else
    }
  },

  componentDidMount() {
    // this locks the view to Portrait Mode
    Orientation.lockToPortrait();

    // this locks the view to Landscape Mode
    // Orientation.lockToLandscape();

    // this unlocks any previous locks to all Orientations
    // Orientation.unlockAllOrientations();

    Orientation.addOrientationListener(this._orientationDidChange);
  },

  _orientationDidChange = (orientation) => {
    if (orientation === 'LANDSCAPE') {
      // do something with landscape layout
    } else {
      // do something with portrait layout
    }
  },

  componentWillUnmount() {
    Orientation.getOrientation((err, orientation) => {
      console.log(`Current Device Orientation: ${orientation}`);
    });


    // Remember to remove listener
    Orientation.removeOrientationListener(this._orientationDidChange);
  }

  render() {
    // ...

    return (
      // ...
    )
  }
}

Orientation Events

addOrientationListener((orientation) => {});

orientation will return one of the following values:

• LANDSCAPE
• PORTRAIT
• PORTRAITUPSIDEDOWN
• UNKNOWN

removeOrientationListener((orientation) => {});

addSpecificOrientationListener((specificOrientation) => {});

specificOrientation will return one of the following values:

• LANDSCAPE-LEFT
• LANDSCAPE-RIGHT
• PORTRAIT
• PORTRAITUPSIDEDOWN
• UNKNOWN

removeSpecificOrientationListener((specificOrientation) => {});

API

• lockToPortrait()
• lockToLandscape()
• lockToLandscapeLeft()
• lockToLandscapeRight()
• unlockAllOrientations()
• getOrientation((err, orientation) => {})
• getSpecificOrientation((err, specificOrientation) => {})
