当我尝试使用 Fire Base 身份验证登录我的应用程序时，它显示电子邮件地址已被另一个帐户使用。我无法弄清楚问题所在。
public class LoginActivity extends AppCompatActivity {
private EditText login_email, login_password;
private Button login_button;
private FirebaseAuth firebaseAuth;
private ProgressDialog progressDialog;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
login_button = (Button) findViewById(R.id.btnLogin);
login_email = (EditText) findViewById(R.id.login_email);
login_password = (EditText) findViewById(R.id.login_password);
firebaseAuth = FirebaseAuth.getInstance();
}
public void onClickLoginButton(View view) {
progressDialog = ProgressDialog.show(LoginActivity.this, " Please Wait...", "its processing", true);
firebaseAuth.createUserWithEmailAndPassword(login_email.getText().toString(), login_password.getText().toString())
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
progressDialog.dismiss();
if (task.isSuccessful()) {
Toast.makeText(LoginActivity.this, "Login Successfull...Bingo...", Toast.LENGTH_LONG).show();
Intent i = new Intent(LoginActivity.this, ProfileActivity.class);
i.putExtra("Email", firebaseAuth.getCurrentUser().getEmail());
startActivity(i);
} else {
Log.e("ERROR", task.getException().toString());
Toast.makeText(LoginActivity.this, task.getException().getMessage(), Toast.LENGTH_LONG).show();
}
}
});
}
}
最佳答案
firebaseAuth.createUserWithEmailAndPassword(email,password) 这用于创建新用户..
要登录现有用户，您可以使用firebaseAuth.signInWithEmailAndPassword(email,password)
