react原生Android自定义原生模块实现错误

Question

我试图在android中为react原生开发原生模块。与https://facebook.github.io/react-native/docs/native-modules-android.html#content的链接完全一致

但它给了我错误

/ReactNativeJS: undefined is not an object (evaluating '_ToastAndroid2.default.show')

我已经实现了toastandroid.js

'use strict';
/**
 * This exposes the native ToastAndroid module as a JS module. This has a
 * function 'show' which takes the following parameters:
 *
 * 1. String message: A string with the text to toast
 * 2. int duration: The duration of the toast. May be ToastAndroid.SHORT or
 *    ToastAndroid.LONG
 */
import { NativeModules } from 'react-native';
module.exports = NativeModules.ToastAndroid;

然后在其他Jsfiles中尝试使用

import ToastAndroid from './ToastAndroid';

Answer 1

更改模块名称“ToastAndroid”，因为ToastAndroid模块已经在react-native包中。
