A react-native module that can listen on orientation changing of device, get current orientation, lock to preferred orientation. (cross-platform support)

• lock screen orientation to PORTRAIT|LANDSCAPE-LEFT|PORTRAIT-UPSIDEDOWN|LANDSCAPE-RIGHT.
• listen on orientation changing of device
• get the current orientation of device

v1.1.3

1. add addLockListener/removeLockListener
2. improve android orientation changed event sending condition

v1.1.2

v1.1.1

1. fix show "supported event type for deviceOrientationDidChange..." error in debug
2. fix getAutoRotateState() code error

v1.1.0 BREAK CHANGE

1. split addOrientationListener(function(orientation, deviceOrientation)) to addOrientationListener(function(orientation)) and addDeviceOrientationListener(function(deviceOrientation))
2. make sure when lockToXXX and unlockAllOrientations resend UI orientation event
3. remove setTimout from orientation listener
4. add getAutoRotateState() for android
5. add TypeScript define file

npm install react-native-orientation-locker --save
react-native link react-native-orientation-locker

pod 'react-native-orientation-locker', :path => '../node_modules/react-native-orientation-locker/react-native-orientation-locker.podspec'

Consult the React Native documentation on how to install React Native using CocoaPods.

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

+#import "Orientation.h"

@implementation AppDelegate

// ...

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

@end

Add following to android/app/src/main/AndroidManifest.xml

      <activity
        ....
+       android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
        android:windowSoftInputMode="adjustResize">

          ....

      </activity>

Implement onConfigurationChanged method (in MainActivity.java)

// ...

+import android.content.Intent;
+import android.content.res.Configuration;

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);
+   }

    // ......
}

Whenever you want to use it within React Native code now you can: import Orientation from 'react-native-orientation-locker';

import Orientation from 'react-native-orientation-locker';


  _onOrientationDidChange = (orientation) => {
    if (orientation == 'LANDSCAPE-LEFT') {
      //do something with landscape left layout
    } else {
      //do something with portrait layout
    }
  };

  componentWillMount() {
    //The getOrientation method is async. It happens sometimes that
    //you need the orientation at the moment the js starts running on device.
    //getInitialOrientation returns directly because its a constant set at the
    //beginning of the js code.
    var initial = Orientation.getInitialOrientation();
    if (initial === 'PORTRAIT') {
      //do stuff
    } else {
      //do other stuff
    }
  },

  componentDidMount() {

    Orientation.getAutoRotateState((rotationLock) => this.setState({rotationLock}));
    //this allows to check if the system autolock is enabled or not.

    Orientation.lockToPortrait(); //this will lock the view to Portrait
    //Orientation.lockToLandscapeLeft(); //this will lock the view to Landscape
    //Orientation.unlockAllOrientations(); //this will unlock the view to all Orientations

    //get current UI orientation
    /*
    Orientation.getOrientation((orientation)=> {
      console.log("Current UI Orientation: ", orientation);
    });

    //get current device orientation
    Orientation.getDeviceOrientation((deviceOrientation)=> {
      console.log("Current Device Orientation: ", deviceOrientation);
    });
    */

    Orientation.addOrientationListener(this._onOrientationDidChange);
  },

  componentWillUnmount: function() {
    Orientation.removeOrientationListener(this._onOrientationDidChange);
  }

• addOrientationListener(function(orientation))

When UI orientation changed, callback function will be called. But if lockToXXX is called , callback function will be not called untill unlockAllOrientations. It can return either PORTRAIT LANDSCAPE-LEFT LANDSCAPE-RIGHT PORTRAIT-UPSIDEDOWN UNKNOWN When lockToXXX/unlockAllOrientations, it will force resend UI orientation changed event.

• removeOrientationListener(function(orientation))

• addDeviceOrientationListener(function(deviceOrientation))

When device orientation changed, callback function will be called. When lockToXXX is called, callback function also can be called. It can return either PORTRAIT LANDSCAPE-LEFT LANDSCAPE-RIGHT PORTRAIT-UPSIDEDOWN UNKNOWN

• removeDeviceOrientationListener(function(deviceOrientation))

• addLockListener(function(orientation))

When call lockToXXX/unlockAllOrientations, callback function will be called. It can return either PORTRAIT LANDSCAPE-LEFT LANDSCAPE-RIGHT UNKNOWN UNKNOWN means not be locked.

• removeLockListener(function(orientation))

• lockToPortrait()
• lockToLandscape()
• lockToLandscapeLeft() this will lock to camera left home button right
• lockToLandscapeRight() this will lock to camera right home button left
• unlockAllOrientations()
• getOrientation(function(orientation))
• getDeviceOrientation(function(deviceOrientation))
• getAutoRotateState(function(state)) (android only)

orientation can return one of:

• PORTRAIT
• LANDSCAPE-LEFT camera left home button right
• LANDSCAPE-RIGHT camera right home button left
• PORTRAIT-UPSIDEDOWN
• UNKNOWN

Notice: PORTRAIT-UPSIDEDOWN not support at iOS now
