非常感谢您的帮助。
编辑:添加了 GoogleSignInStatusCodes.getStatusCodeString(result.getStatus().getStatusCode()); 返回 10，对应于 DEVELOPER_ERROR。
我之前已经为 Google map 创建了一个 key ，它包含在我的项目中(在 list 文件中，元标记中)，现在我必须创建另一个 key 吗？如果是，我该如何包含它？
最佳答案
试试下面的代码
private void handleSignInResult(GoogleSignInResult result) {
Log.d(String.valueOf(LoginActivity.this), "handleSignInResult:" + result.isSuccess());
if (result.isSuccess()) {
// Signed in successfully, show authenticated UI.
GoogleSignInAccount acct = result.getSignInAccount();
if (acct != null) {
Intent iWelcomeActivity = new Intent(MainActivity.this, WelcomeActivity.class);
iWelcomeActivity.putExtra("USERNAME", acct.getDisplayName());
iWelcomeActivity.putExtra("EMAIL", acct.getEmail();
);
startActivity(iWelcomeActivity);
}
} else {
// Signed out, show unauthenticated UI.
//updateUI(false);
}
}
当用户点击登录按钮时， Intent 会提示用户选择要登录的 Google 帐户。
onActivityResult 方法，检索登录结果并调用 handleSignInResult(GoogleSignInResult result)。
如果登录成功，您可以调用getSignInAccount 方法 来获取包含登录用户信息的GoogleSignInAccount 对象。
使用 GoogleSignInAccount 对象 以 acct.getDisplayName(),acct.getEmail() 的形式检索信息，并将其传递给下一个 Activity ，如上面的代码所示。
希望对你有帮助
