模板版本:v0.2.2
[!TIP] Github 地址
请到三方库的 Releases 发布地址查看配套的版本信息:@react-native-oh-tpl/react-native-file-viewer Releases 。对于未发布到npm的旧版本,请参考安装指南安装tgz包。
进入到工程目录并输入以下命令:
npm install @react-native-oh-tpl/react-native-file-viewer
yarn add @react-native-oh-tpl/react-native-file-viewer
下面的代码展示了这个库的基本使用场景:
[!WARNING] 使用时 import 的库名不变。
import { StyleSheet, ScrollView, Text, TouchableOpacity } from "react-native";
import DocumentPicker from "react-native-document-picker";
import FileViewer from "react-native-file-viewer";
export function FlieViewerExample() {
const FileViewerTest = async (option?: any) => {
try {
// 使用react-native-document-picker来选择本地文件进行打开
const res: any = await DocumentPicker.pick({
type: [DocumentPicker.types.allFiles]
});
// uri 为本地文件绝对路径
await FileViewer?.open(res[0].uri, option);
} catch (e) {
// error
}
};
const onDismissCb = () => {
// do sth ...
};
return (
<ScrollView style={{ backgroundColor: "skyblue" }}>
<TouchableOpacity onPress={() => FileViewerTest()} style={styles.btn}>
<Text style={styles.btnText}>Toogle Status Bar</Text>
</TouchableOpacity>
<TouchableOpacity onPress={() => FileViewerTest("show_displayName string")} style={styles.btn}>
<Text style={styles.btnText}>Toogle Status Bar (displayName str)</Text>
</TouchableOpacity>
<TouchableOpacity onPress={() => FileViewerTest({ displayName: "show_displayName option" })} style={styles.btn}>
<Text style={styles.btnText}>Toogle Status Bar (displayName opt)</Text>
</TouchableOpacity>
<TouchableOpacity onPress={() => FileViewerTest({ showOpenWithDialog: true, onDismiss: onDismissCb })} style={styles.btn}>
<Text style={styles.btnText}>Toogle Status Bar (onDismiss)</Text>
</TouchableOpacity>
<TouchableOpacity onPress={() => FileViewerTest({ showOpenWithDialog: true })} style={styles.btn}>
<Text style={styles.btnText}>Toogle Status Bar (showOpenWithDialog)</Text>
</TouchableOpacity>
<TouchableOpacity onPress={() => FileViewerTest({ showAppsSuggestions: true })} style={styles.btn}>
<Text style={styles.btnText}>Toogle Status Bar (showAppsSuggestions)</Text>
</TouchableOpacity>
</ScrollView>
);
}
const styles = StyleSheet.create({
TextInput: {
height: 40,
borderColor: "#ccc",
borderWidth: 1,
borderRadius: 4,
width: "90%"
},
btn: {

本库已经适配了 Codegen
,在使用前需要主动执行生成三方库桥接代码,详细请参考 Codegen 使用文档。
目前鸿蒙暂不支持 AutoLink,所以 Link 步骤需要手动配置。
首先需要使用 DevEco Studio 打开项目里的鸿蒙工程 harmony
{
...
"overrides": {
"@rnoh/react-native-openharmony" : "./react_native_openharmony"
}
}
目前有两种方法:
- 通过 har 包引入(在 IDE 完善相关功能后该方法会被遗弃,目前首选此方法);
- 直接链接源码。
方法一:通过 har 包引入(推荐)
[!TIP] har 包位于三方库安装路径的
harmony
文件夹下。
打开 entry/oh-package.json5
,添加以下依赖
"dependencies": {
"@rnoh/react-native-openharmony": "file:../react_native_openharmony",
"@react-native-oh-tpl/react-native-file-viewer": "file:../../node_modules/@react-native-oh-tpl/react-native-file-viewer/harmony/file_viewer.har"
}
点击右上角的 sync
按钮
或者在终端执行:
cd entry
ohpm install
方法二:直接链接源码
[!TIP] 如需使用直接链接源码,请参考直接链接源码说明
打开 entry/src/main/ets/RNPackagesFactory.ts
,添加:
...
+ import { RNFileViewerPackage } from '@react-native-oh-tpl/react-native-file-viewer/ts';
export function createRNPackages(ctx: RNPackageContext): RNPackage[] {
return [
new SamplePackage(ctx),
+ new RNFileViewerPackage(ctx)
];
}
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。
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。

[!TIP] "Platform"列表示该属性在原三方库上支持的平台。
[!TIP] "HarmonyOS Support"列为 yes 表示 HarmonyOS 平台支持该属性;no 则表示不支持;partially 表示部分支持。使用方法跨平台一致,效果对标 iOS 或 Android 的效果。
Name | Description | Type | Required | Platform | HarmonyOS Support |
---|---|---|---|---|---|
filepath | The absolute path where the file is stored. The file needs to have a valid extension to be successfully detected. Use react-native-fs constants to determine the absolute path correctly. | string | yes | All | yes |
options (optional) | Some options to customize the behaviour. See below. | Object | no | All | yes |
Name | Description | Type | Required | Platform | HarmonyOS Support |
---|---|---|---|---|---|
