React-Native|React-Native 使用第三方库时遇到的坑及解决方法 React-Native使用第三方库时遇到

运行版本：
"react-native": "0.54.1",
"react-native-navigation": "1.1.407",
"jcore-react-native": "^1.2.5",
"jpush-react-native": "^2.2.0",
"react-native-swiper": "1.5.13",
"react-native-tab-navigator": "0.3.4"
1.安卓环境在react-native-navigation的导航环境下，部分功能在页面返回后缺失，如react-native-swiper轮播失效，react-native-scrollable-tab-view的UI效果失灵解决方法如下步骤：
第一步：~项目路径/node_modules/react-native-navigation/android/app/src/main/java/com/reactnativenavigation/NavigationApplication.java
最下方加上这段代码

//先import import com.facebook.react.shell.MainReactPackage; //最下方加上 @Nullable public abstract MainReactPackage readyMainReactPackage();

第二步：~项目目录/node_modules/react-native-navigation/android/app/src/main/java/com/reactnativenavigation/react/NavigationReactGateway.java
将原来的getPackages的方法替换为：

@Override protected List getPackages() { List result = new ArrayList<>(); List additionalReactPackages = NavigationApplication.instance.createAdditionalReactPackages(); if (additionalReactPackages != null) result.addAll(additionalReactPackages); if (!containsInstanceOfClass(result, MainReactPackage.class)) { MainReactPackage mainReactPackage = NavigationApplication.instance.readyMainReactPackage(); if (mainReactPackage == null) { result.add(new MainReactPackage()); } else { result.add(mainReactPackage); } } if (!containsInstanceOfClass(result, NavigationReactPackage.class)) { result.add(new NavigationReactPackage()); }return result; }

2.安卓使用JPush的RN版本的时候，应用关闭的情况下点击推送，推送跳转无法跳转，解决方法如下 ~项目目录/node_modules/jpush-react-native/android/src/main/java/cn/jpush/reactnativejpush/JPushModule.java
加上这段代码

@ReactMethod public void appExit() { mRAC = null; }

然后在js代码里面的一般加载JPush方法的Main类里面加上

const JPushModuleOrigin = NativeModules.JPushModulecomponentWillUnmount() { if (Platform.OS === 'android') { JPushModuleOrigin.appExit(); } }

3.使用native-echarts第三方插件做图标的时候，安卓环境下会出现图标无法显示和会滑动的bug，解决方法如下 ~项目目录/node_modules/native-echarts/scr/components/Echarts/index.js下的代码替换为如下代码

import React, { Component } from 'react'; import { WebView, View, StyleSheet , Platform } from 'react-native'; import renderChart from './renderChart'; import echarts from './echarts.min'; export default class App extends Component { componentWillReceiveProps(nextProps) { if(nextProps.option !== this.props.option) { this.refs.chart.reload(); } }render() {let scalesPageToFit = Platform.OS === 'ios' ? false : true let source = Platform.OS === 'ios' ? require('./tpl.html') : {'uri':'file:///android_asset/tpl.html'}return ( this.props.onPress ? this.props.onPress(JSON.parse(event.nativeEvent.data)) : null} /> ); } }

【React-Native|React-Native 使用第三方库时遇到的坑及解决方法】然后将~项目目录/node_modules/native-echarts/scr/components/Echarts/tpl.html文件替换到
~项目目录/android/app/src/main/assets/tpl.html即可
