android - 如何在 Android 中检索我登录的谷歌帐户的名字和姓氏？

Question

我有一个带有 google 身份验证的简单应用程序，我想显示一条欢迎消息。如果电子邮件帐户是 johnsmith@gmail.com，我想要一个Toast “Welcome John Smith!” 我该怎么做？

这是我的代码:

if (user == null) {
        startActivityForResult(AuthUI.getInstance().createSignInIntentBuilder().build(), SIGN_IN_REQUEST_CODE);
    } else {
        Toast.makeText(MainActivity.this, "Welcome " + userName, Toast.LENGTH_SHORT).show();
    }

我尝试使用此代码，但我只得到用户名，而不是名字和姓氏。

AccountManager manager = (AccountManager) getSystemService(ACCOUNT_SERVICE);
Account[] list = manager.getAccounts();

提前致谢!

onActivityResult:

public void onActivityResult(int requestCode, int resultCode, Intent result) {
    if (requestCode == GOOGLE_REQUEST_CODE) { // Google + callback
       handleSignInResult(Auth.GoogleSignInApi.getSignInResultFromIntent(result));
       }
}

handleSignInResult :

private void handleSignInResult(GoogleSignInResult googleSignInResult) {
    if (googleSignInResult.isSuccess()) {
        GoogleSignInAccount acct = googleSignInResult.getSignInAccount();
        if (acct != null) {
            //get the data you need from GoogleSignInAccount
            }
        } else {
            Toast.makeText(context.getApplicationContext(), "error", Toast.LENGTH_SHORT).show();
        }
    }

您可以在 GoogleSignInAccount 上找到更多信息: https://developers.google.com/android/reference/com/google/android/gms/auth/api/signin/GoogleSignInAccount
