图片加载不出来，刚开始以为是url的问题，结果在浏览器上直接访问网络地址是可以看到图片的，后来看了别人的博客才知道原来是没有配置网络权限的问题

 

 

解决方法：配置网络权限

1. 用vscode打开项目的话：在项目中的android/src/main/AndroidManifest.xml中添加下列代码：

     <!-- 配置网络权限 -->
     <uses-permission android:name="android.permission.READ_PHONE_STATE" />
     <uses-permission android:name="android.permission.INTERNET" />
     <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
     <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

 

 

注意配置网络权限的位置： 跟<application>是同一级

2. 第二步：在模拟器里要打开网络（移动数据），然后再shift+R热加载一下项目就可以加载到图片了
