android 修改头像后并上传到阿里云
16lz
2021-01-23
说句题外话，之前打算修改头像后把头像的base64字符串或字节数组直接传给后台，但是考虑到传输中出现的各种问题以及我后台接收时的不方便，所以改为了android端直接上传到阿里云，然后android直接传一个远程url给后台存储，这样就方便多了。
话不多说，代码走起。
首先你要在你的清单文件中加入各项权限以及一个provider
filepaths.xml
<?xml version="1.0" encoding="utf-8"?> build.grade
//上传头像 implementation 'com.facebook.fresco:fresco:1.1.0' annotationProcessor 'com.jakewharton:butterknife-compiler:8.4.0' implementation 'com.jakewharton:butterknife:8.4.0' implementation 'com.aliyun.dpa:oss-android-sdk:+'
activity_main.xml中就一个圆形的头像空间，其中这个圆形头像是我自定义的
