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
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。

val pendingResultTask: Task<AuthResult>? = auth.pendingAuthResult
if (pendingResultTask != null) {
pendingResultTask

Toast.makeText(this, "User exist", Toast.LENGTH_LONG).show()
}

})
.addOnFailureListener(
OnFailureListener {
// Handle failure.
Toast.makeText(this, "Error2 : $it", Toast.LENGTH_LONG).show()
})
}
}
}
*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。
