react-native-immersive

本项目基于 原库react-native-immersive 开发。

该第三方库的仓库已迁移至 Gitcode，且支持直接从 npm 下载，新的包名为：@react-native-ohos/react-native-immersive 版本所属关系如下：

简介

一款用于开启 Immersive Mode（沉浸式全屏模式），可以隐藏状态栏 + 底部导航栏；

安装与使用

进入到工程目录并输入以下命令

npm

npm install @react-native-ohos/react-native-immersive

yarn

yarn add @react-native-ohos/react-native-immersive

下面的代码展示了这个库的基本使用场景：

import React, { Component } from 'react'
import { AppRegistry, StyleSheet, Text, View, Button, TextInput, Alert, Modal } from 'react-native'
import { Immersive } from 'react-native-immersive'

class testReactNative extends Component {
  constructor (props) {
    super(props)
    
    Immersive.getImmersive().then((immersiveState) => {
        console.log('init [getImmersiveState]', immersiveState)
        this.setState({ immersiveState,isImmersive: immersiveState.isImmersiveOn })
        if(immersiveState.isImmersiveOn){
          Immersive.on()
        }
      }).catch((err) => {
        console.error('[getImmersiveState] error', err)
   })

    this.setImmersiveOn = () => {
      let startTime = Date.now();
      Immersive.on()
      let endTime = Date.now();
      console.log("react-native-immersive on time:", endTime - startTime, "ms");
      this.setState({ isImmersive: true })
    }
    this.setImmersiveOff = () => {
      let startTime = Date.now();
      Immersive.off()
      let endTime = Date.now();
      console.log("react-native-immersive off time:", endTime - startTime, "ms");
      this.setState({ isImmersive: false })
    }
    this.setImmersiveTrue = () => {
      let startTime = Date.now();
      Immersive.setImmersive(true)
      let endTime = Date.now();
      console.log("react-native-immersive setImmersive time:", endTime - startTime, "ms");
      this.setState({ isImmersive: true })
    }
    this.setImmersiveFalse = () => {
      Immersive.setImmersive(false)
      this.setState({ isImmersive: false })
    }
    this.addImmersiveListener = () => {
      if(!this.state.isAddListener){
        console.log("Immersive---------> addImmersiveListener",this.restoreImmersive);
        let startTime = Date.now();
        Immersive.addImmersiveListener(this.restoreImmersive)
        let endTime = Date.now();
        console.log("react-native-immersive addImmersiveListener time:", endTime - startTime, "ms");
        this.setState({ isAddListener: true })
      }
    }
    this.removeImmersiveListener = () => {
      if(this.state.isAddListener){
        console.log("Immersive---------> removeImmersiveListener",this.restoreImmersive);
        let startTime = Date.now();
        Immersive.removeImmersiveListener(this.restoreImmersive)
        let endTime = Date.now();
        console.log("react-native-immersive removeImmersiveListener time:", endTime - startTime, "ms");
        this.setState({ isAddListener: false })
      }
    }

  
    this.getImmersiveState = () => {
      let startTime = Date.now();
      Immersive.getImmersive().then((immersiveState) => {
        let endTime = Date.now();
        console.log("react-native-immersive getImmersive time:", endTime - startTime, "ms");
        console.log('[getImmersiveState]', immersiveState)
        this.setState({ immersiveState })
      }).catch((err) => {
        console.error('[getImmersiveState] error', err)
      })
    }

    this.restoreImmersive = () => {
      Alert.alert("Callback","The registered listener callback has been invoked")
    }

    this.state = {
      isAddListener: false,
      isImmersive: false,
      isRestoreImmersive: true,
      immersiveState: null
    }
  }

    const { isImmersive, immersiveState } = this.state
    return (

const styles = StyleSheet.create({
  container: { flex: 1, padding: 24 },
  containerTest: { alignItems: 'stretch', justifyContent: 'center', flex: 1 },
  text: { textAlign: 'center', fontSize: 14 }
})

export default testReactNative;
AppRegistry.registerComponent('testReactNative', () => testReactNative)

Link

使用AutoLink的工程需要根据该文档配置，Autolink框架指导文档：https://gitcode.com/CPF-RN/ohos_react_native/blob/master/docs/zh-cn/Autolinking.md

如您使用的版本支持 Autolink，并且工程已接入 Autolink，可跳过ManualLink配置。

运行

点击右上角的 sync 按钮

或者在终端执行：

cd entry
ohpm install

然后编译、运行即可。

约束与限制

兼容性

要使用此库，需要使用正确的 React-Native 和 RNOH 版本。另外，还需要使用配套的 DevEco Studio 和 手机 ROM。

在以下版本验证通过。

1. RNOH: 0.72.79; SDK: HarmonyOS 5.1.1 Release SDK; IDE: DevEco Studio 5.1.1 Release; ROM: 5.0.1.120;
2. RNOH: 0.77.18; SDK: HarmonyOS 6.0.0 Release SDK; IDE: DevEco Studio 6.0.0.858; ROM: 6.0.0.112;

编译运行API要求

1. 此库所有版本引入isImmersiveLayout，实现了获取当前窗口是否是沉浸式的功能，此API需要在支持API12+的工程编译，并在支持API20+的ROM上运行，方可生效。
