                        {
                            this.selectedPhoneNumbers().map(
                                n => <View style={{ marginTop: 5, marginBottom: 5 }}><Button title={'拨打：' + n} onPress={e => this.makePhoneCall(n)} /></View>

                </RBSheet>

函数代码

//复制
copyTextMessageToClipboard = () => {
        Clipboard.setString(this.state.selectedTextMessage.text);
        this.RBSheet.close();
    }
//拨打号码
makePhoneCall = (number) => {
        Linking.openURL('tel:' + number);
        this.RBSheet.close();
    }
//保存到通讯录
    savePhoneCall = (number) => {
        if (number && number.length > 0) {
            let name = "";
            MyAppModule.addContactMulti1(name, number);
        }
    };

MyAppModule.js

// MyAppModule.js
import { NativeModules } from "react-native";
// 下一句中的MyAppModule即对应上文
// public String getName()中返回的字符串
export default NativeModules.MyAppModule;
