react-native-orientation-locker

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

Feature

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

ChangeLog

Notice

1. RN 0.58 + Android target SDK 27 maybe cause Issue: java.lang.IllegalStateException: Only fullscreen activities can request orientation problem, see [#55] for a solution.

2. orientationDidChange will be delayed on iPads if we set upside down to true. Simply disable upside down for iPad and everything works like a charm ([#78] Thanks truongluong1314520)

3. If you get the following build error on iOS: ld: library not found for -lRCTOrientation-tvOS Just remove it from linked libraries and frameworks

Installation

Using yarn (RN 0.60 and and above)

    yarn add react-native-orientation-locker

Using yarn (RN 0.59 and and below)

    yarn add react-native-orientation-locker
    react-native link react-native-orientation-locker

Using CocoaPods (iOS Only)

Run pod install in the ios directory. Linking is not required in React Native 0.60 and above.

Configuration

iOS

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

Android

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);
+   }
 
    // ......
}

Add following to MainApplication.java (This will be added automatically by the react-native-link. If not, please manually add the following )

//...
+import org.wonday.orientation.OrientationPackage;
 
    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
        //...
+        new OrientationPackage(),
        //...
      );
    }
//...

Usage

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);
  }

Events

• 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))

• removeAllListeners()

Functions

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