Lock device orientation - React Native (Android)

问题:

I'm using React Native 0.29 and developing for Android. I'm trying to lock the device orientation. What I need is to lock the screen in portrait mode. I tried with this repository https://github.com/yamill/react-native-orientation but it is not supporting RN 0.29 yet.

Is there any way I can lock the device orientation? Maybe any native Android hack with android studio?

回答1:

Just add android:screenOrientation="portrait" to the activity in the AndroidManifest.xml.

There is a pull request for this to work on 0.29.2 and above: https://github.com/yamill/react-native-orientation/pull/85

If you use his version, it should work on 0.29.2 and above: https://github.com/youennPennarun/react-native-orientation

Steps:

1. unlink the previous installation with rnpm unlink react-native-orientation
2. rm -rf node_modules/react-native-orientation

3. in your package.json edit the entry of react-native-orientation to be as:

   "react-native-orientation": "youennPennarun/react-native-orientation"

4. npm install

5. react-native link react-native-orientation

Things should work after this. You can track the progress of the PR and switch to main repo when it has been merged.

2017 Update

Currently, there is also another way to do it once for both Android and iOS by adding:

"orientation": "portrait"

in app.json if you're using Expo:

{
  "expo": {
    "name": "My app",
    "slug": "my-app",
    "sdkVersion": "21.0.0",
    "privacy": "public",
    "orientation": "portrait"
  }
}

Or at runtime:

ScreenOrientation.allow()

Example:

ScreenOrientation.allow(ScreenOrientation.Orientation.PORTRAIT);

Note that it only works if you're building with Expo but since this is currently (as of 2017) recommended in official guides on React Native Blog then probably a lot of people are using it so it's worth mentioning as an interesting solution in addition to hacking the Android-specific XML configuration files.

react-native-orientation - is no longer compatible with new version (I have tried 0.39.2). After linking this module I have the compiler's error. As I got it, now we should use react-native-orientation-listener

npm install --save react-native-orientation-listener
rnpm link

Step:1

npm install git+https://github.com/yamill/react-native-orientation.git --save

Step2: react-native link Step:3 Modify the MainApplication.java file with:

import com.github.yamill.orientation.OrientationPackage;// import

@Override
protected List getPackages() {
return Arrays.asList(
new MainReactPackage(),
new OrientationPackage() //add this
);
}

You can use react-native-orientation-locker.

The 'react-native-orientation' has been deprecated. Using the 'react-native-orientation-locker' component, you would be able to detect the current orientation, as well as locking it to Portrait/Landscape by using:

Orientation.lockToPortrait();

Orientation.lockToLandscapeLeft();

Even release the locks using

Orientation.unlockAllOrientations();
