深层链接和android返回键的例子

expo + react-native + react navigation v5

Configuration

在 /android/app/src/main/AndroidManifest.xml 中配置 scheme 访问前缀

<intent-filter>
        <action android:name="android.intent.action.VIEW"/>
        <category android:name="android.intent.category.DEFAULT"/>
        <category android:name="android.intent.category.BROWSABLE"/>
        <data android:scheme="myapp"/>
        <data android:scheme="com.notbrent.mofengfs"/>
        <data android:scheme="a08"/>
</intent-filter>

或者命令行执行

npx uri-scheme add a08 --android

配置深层链接

import * as Linking from 'expo-linking';

export default {
  prefixes: ['a08://'],
  config: {
    screens: {
        Root: {
          screens: {
            TabOne: {
              screens: {
                TabOneScreen: 'one',
              },
            },
            TabTwo: {
              screens: {
                TabTwoScreen: 'two',
              },
            },
          },
        },
      //   NotFound: '*',
      List: {
        path: 'list/:id',
        parse: {
          id: (id: any) => `${id}`
        }
      },
      Detail: {
        path: 'detail/:id',
        parse: {
          id: (id: any) => `${id}`
        }
      }
    }
  },
};

NavigationContainer 中调用深层链接

<NavigationContainer
      linking={LinkingConfiguration}
      theme={colorScheme === 'dark' ? DarkTheme : DefaultTheme}>
      <RootNavigator />
</NavigationContainer>

android backbutton 不能返回上一页的解决办法

每个非首页屏幕都要添加goBack代码

import { BackHandler } from 'react-native';

export const listScreen = ({ navigation: { goBack } }) => {

  // 返回上一屏  start
  function handleBackButtonClick() {
    goBack();
    return true;
  }

  useEffect(() => {
    BackHandler.addEventListener('hardwareBackPress', handleBackButtonClick);
    return () => {
      BackHandler.removeEventListener('hardwareBackPress', handleBackButtonClick);
    };
  }, []);
  // 返回上一屏  end

 ...
 ...

how to use

install

git clone https://github.com/mofengfs/DeepLink-BackHandler-Example.git

//Project root directory
yarn

//Open the emulator  start
yarn android

params/stack list/detail

npx uri-scheme open a08://list/123 --android
npx uri-scheme open a08://detail/123 --android

tab test

npx uri-scheme open a08://two --android

Expected Results:

Open the app manually, when I click the android backbutton, I can go back to the previous screen.
