react-native-extra-dimensions-android

Access additional display metrics on Android devices: status bar height, soft menu bar height, real screen size.

ExtraDimensions

This module allows you to access additional display metrics on Android devices. (RN 0.57.0+)

  • Actual width and height of the screen (including elements such as soft menu bar)
  • Soft menu height
  • Status bar height
  • Smart bar height (MeiZu)

Why?

There is currently a bug in React Native where Dimensions.get('window').height sometimes returns
the wrong value.

Also, some apps may want to set the background of status bar and soft menu bar to transparent, thus the top-level
view needs to fill up the real screen size.

Installation

  1. Install with npm

    npm install react-native-extra-dimensions-android --save

  2. linking

    react-native link react-native-extra-dimensions-android

2b. You may have to register the module (in android/app/src/main/java/com/YOUR-PROJECT-NAME/MainApplication.java)
react-native link should automatically do the following for you. If it doesn't, you might have to add it yourself.

```
import ca.jaysoo.extradimensions.ExtraDimensionsPackage;  // <--- import

public class MainApplication extends Application implements ReactApplication {
  ......
  protected List<ReactPackage> getPackages() {
    return Arrays.<ReactPackage>asList(
      new MainReactPackage(),
      new ExtraDimensionsPackage()  // <--- add here
    );
  }
  ......
}
```
  1. As this is a package with Java, you'll need to rebuild the project.

e.g. react-native run-android

  1. Whenever you want to use it within React Native code now you can:

var ExtraDimensions = require('react-native-extra-dimensions-android');

Or, if you are using ES6

import ExtraDimensions from 'react-native-extra-dimensions-android';
