一.初始化一个ReactNative项目

• 在指定目录运行命令:react-native init Vince(项目名称)  //其过程就是在使用CLI工具构建项目,
• 命令行代码

F:\React>react-native init Vince

This will walk you through creating a new React Native project in F:\React\Vince

Installing react-native package from npm...

Setting up new React Native app in F:\React\Vince

react@15.0.2 node_modules\react

   Hit the Run button

To run your app on Android:

   Have an Android emulator running (quickest way to get started), or a device connected

   cd F:\React\Vince

   react-native run-android

• 创建完的项目目录结构为:
• 

• 在模拟器端运行
• 使用AndroidStudio运行创建模拟器,并运行
• 项目目录下运行命令react-native run-android
• 模拟器中出现如下界面,则代表构建项目成功
