在React Native中添加共享操作/扩展

Question

尝试构建一个React Native应用程序,该应用程序在"共享"菜单(Android的"共享操作","iOS的共享扩展")中注入一个菜单项,并在应用程序中接收共享项.是否有一个组件,如果没有,最好的方法是什么？

我为此实现了一个模块:https://www.npmjs.com/package/react-native-share-menu(目前仅适用于Android).

这是如何使用它:

安装模块:

npm i --save react-native-share-menu

在android/settings.gradle中:

...
include ':react-native-share-menu', ':app'
project(':react-native-share-menu').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-share-menu/android')

在android/app/build.gradle中:

...
dependencies {
    ...
    compile project(':react-native-share-menu')
}

注册模块(在MainActivity.java中):

import com.meedan.ShareMenuPackage;  // <--- import 

public class MainActivity extends ReactActivity {
......
    @Override
    protected List<ReactPackage> getPackages() {
        return Arrays.<ReactPackage>asList(
            new MainReactPackage(),
            new ShareMenuPackage()  // <------ add here      
        );
    }
......
}

例:

import React, {
    AppRegistry,
    Component,
    Text,
    View
} from 'react-native';
import ShareMenu from 'react-native-share-menu';

class Test extends Component {
    constructor(props) {
        super(props); 
        this.state = {
            sharedText: null
        };
    }

    componentWillMount() {
        var that = this;
        ShareMenu.getSharedText((text :string) => {
            if (text && text.length) {
                that.setState({ sharedText: text });
            }
        })
    }

    render() {
        var text = this.state.sharedText;
        return (
            <View>
                <Text>Shared text: {text}</Text>
            </View>
        );
    }
}

AppRegistry.registerComponent('Test', () => Test);
