问使用RN和expo更改android上的导航栏？

EN

{
  "androidNavigationBar": {
     /*
        Determines to show or hide bottom navigation bar.
        "true" to show, "false" to hide.
        If set to false, status bar will also be hide. As it's a general rule to hide both status bar and navigation bar on Android developer official docs.
      */
    "visible": BOOLEAN,
    /*
      Configure the navigation bar icons to have light or dark color.
      Valid values: "light-content", "dark-content".
    */
    "barStyle": STRING,

    /*
      Configuration for android navigation bar.
      6 character long hex color string, eg: "#000000"

white : "#ffffff" , black : "#000000"

example = async () => {
      try{
        if (Platform.OS == 'android') {
          const response = await changeNavigationBarColor('#ffffff');
          console.log(response)// {success: true}
          }
      }catch(e){
          console.log(e)// {success: false}
      }

  };

 {
            this.example();
          }}
        />


IF not I suggest you try another module. react-native-navbar-color


npm install --save react-native-navbar-color
react-native link react-native-navbar-color


Example.js

import NavigationBar from 'react-native-navbar-color'

export default class App extends Component {
    componentDidMount() {
        NavigationBar.setColor('#ffab8e')
    }
...
