如何在安卓中使用 Firebase 通过 GitHub 登录后更新用户的个人资料？

原文:https://www . geesforgeks . org/如何更新-用户-档案-通过 github-使用-firebase-in-android/

在本文中，我们将学习更新通过 GitHub 登录应用程序的用户的个人资料。该档案将通过用户的 GitHub 信息更新，如 GitHub Id、姓名、关注者、追随者等。开始吧！

第一步:首先设置你的 app，让用户可以通过 GitHub 登录。所以你需要在 firebase 的帮助下使用 GitHub 认证用户。为此，请遵循文章中的所有步骤:在安卓系统中使用 Github 认证用户。

第二步:更新配置文件

为此，如下所示，在 signInWithGithubProvider()方法的 else 部分声明一个类型映射的变量 say‘user ’,使用additionalUserInfo提取用户的 Github 配置文件信息。

private fun signiwitthgithubprovider(){ 0

。。。

如果{

。。。}

else {

。。。

val 用户:地图 = it.additionalUserInfo！！。简介为地图 //指 AuthResult！

。。。

}

}

使用 additionalUserInfo，所有需要的信息将从 MainActivity 发送到 HomePageActivity(使用 Intent)，其中包含用户的配置文件信息。所有代码与本文中的相同找出不同之处，并添加更新用户配置文件所需的代码行。下面是 MainActivity.kt 文件的代码。代码中添加了注释，以更详细地理解代码。

*第三步:创建一个新的空活动*

参考本文如何在安卓工作室新建活动，新建一个活动。将活动命名为主页活动。导航到应用程序> res >布局> activity_home_page.xml 并将下面的代码添加到该文件中。下面是 activity_home_page.xml 文件的代码。
