Java 在片段中使用Google登录按钮
我将在我的android应用程序中加入Google sign。但唯一的区别是我在片段中使用了Signin按钮，而不是activity。所以，当我试图通过单击登录按钮登录用户时，我无法登录。当我调试代码时，我知道onActivityResult方法中的Google身份验证失败 WelcomeActivity.javaJava 在片段中使用Google登录按钮,java,android,firebase-authentication,google-signin,Java,Android,Firebase Authentication,Google Signin,我将在我的android应用程序中加入Google sign。但唯一的区别是我在片段中使用了Signin按钮，而不是activity。所以，当我试图通过单击登录按钮登录用户时，我无法登录。当我调试代码时，我知道onActivityResult方法中的Google身份验证失败 WelcomeActivity.java public class WelcomeActivity extends AppCompatActivity { private static final String TA

有人能告诉我哪里做错了吗？非常感谢。非常感谢您的帮助。请尝试此代码并为我工作 在创建您的活动时
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(getString(R.string.default_web_client_id))
.requestServerAuthCodegetString(R.string.default_web_client_id)
.requestEmail()
.build();
mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
.enableAutoManage(getActivity(), this)
.addApi(Plus.API, Plus.PlusOptions.builder().build())
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
mCallbackManager.onActivityResult(requestCode, resultCode, data);
if (requestCode == mController.RC_GET_TOKEN) {
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
handleSignInResult(result);
}
}
单击Google plus登录按钮的onClick
try {
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(signInIntent, RC_GET_TOKEN);
}catch (Exception e){
e.printStackTrace();
}

覆盖ActivityResult上的
@Override

super.onActivityResult(requestCode, resultCode, data);
mCallbackManager.onActivityResult(requestCode, resultCode, data);
if (requestCode == mController.RC_GET_TOKEN) {

单击Google plus登录按钮的onClick
try {
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(signInIntent, RC_GET_TOKEN);
}catch (Exception e){
e.printStackTrace();
}
Jetpack导航组件和Kotlin的另一个解决方案如下所述。此处无需在活动中添加任何代码：
class SignInFragment : Fragment(R.layout.fragment_signin) {
companion object {
const val GOOGLE_SIGN_IN = 1903
}
private lateinit var auth: FirebaseAuth
private lateinit var googleSignInClient: GoogleSignInClient
override fun onActivityCreated(savedInstanceState: Bundle?) {
super.onActivityCreated(savedInstanceState)
auth = Firebase.auth
googleSignInClient = GoogleSignIn.getClient(requireContext(), getGSO())
btnSignIn.setOnClickListener { signIn() }
}
private fun signIn() {
val signInIntent = googleSignInClient.signInIntent
startActivityForResult(signInIntent, GOOGLE_SIGN_IN)
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == GOOGLE_SIGN_IN) {
val task = GoogleSignIn.getSignedInAccountFromIntent(data)
try {
val account = task.getResult(ApiException::class.java)!!
firebaseAuthWithGoogle(account.idToken!!)
} catch (e: ApiException) {
//handle error
}
}
}
private fun firebaseAuthWithGoogle(idToken: String) {
val credential = GoogleAuthProvider.getCredential(idToken, null)
auth.signInWithCredential(credential)
.addOnCompleteListener(requireActivity()) { task ->
if (task.isSuccessful) {
//handle success
} else {
//handle error
}
}
}
private fun getGSO(): GoogleSignInOptions {
return GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(getString(R.string.default_web_client_id))
.requestEmail()
.build()
}
}
xml中的登录按钮：
<com.google.android.gms.common.SignInButton
android:id="@+id/btnSignIn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:buttonSize="wide">
