我试图从Firebase Auth of Email / Password Verification中获取用户ID，但它不会显示在Firebase数据库中。
这是我的DriverLogin.class代码：
public class DriverLogin extends AppCompatActivity {
private static final String TAG = "EmailPassword";
private EditText mEmail;
private EditText mPass;
private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener firebaseAuthListener;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_driver_login);
mAuth = FirebaseAuth.getInstance();
firebaseAuthListener= new FirebaseAuth.AuthStateListener() {
@Override
public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
if(user != null){
Intent intent = new Intent(DriverLogin.this,DriverMain.class);
startActivity(intent);
finish();
return;
}
}
};
//editText
mEmail = findViewById(R.id.DriverEmail);
mPass = findViewById(R.id.DriverPass);
//Btn
findViewById(R.id.DriverSign).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
signUp(mEmail.getText().toString(), mPass.getText().toString());
}
});
findViewById(R.id.DriverLogbtn).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
signIn(mEmail.getText().toString(), mPass.getText().toString());
}
});
}
//CreateAccount with Email and Password
private void signUp(final String email, final String password) {
Log.d(TAG, "CreateAccount:" + email);
if (!validateForm()) {
return;
}
mAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
Log.d(TAG, "createUserWithEmail:success");
Toast.makeText(DriverLogin.this, "Registered Successfully",
Toast.LENGTH_SHORT).show();
} else {
String user_id = mAuth.getCurrentUser().getUid();
DatabaseReference driverDb = FirebaseDatabase.getInstance().getReference().child("Users").child("Driver").child(user_id);
driverDb.setValue(true);
Toast.makeText(DriverLogin.this, "Something went wrong",
Toast.LENGTH_SHORT).show();
}
}
});
}
//---------------------------------------------LOGIN------------------------------------//
//Login Existing Account
private void signIn(final String email, final String pass) {
Log.d(TAG, "CreateAccount:" + email);
if (!validateForm()) {
return;
}
mAuth.signInWithEmailAndPassword(email, pass).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
Log.d(TAG, "signInWithEmail:success");
FirebaseUser user = mAuth.getCurrentUser();
Toast.makeText(DriverLogin.this, "Logged in Successfully", Toast.LENGTH_SHORT).show();
} else {
// If sign in fails, display a message to the user.
Log.w(TAG, "signInWithEmail:failure", task.getException());
Toast.makeText(DriverLogin.this, "Authentication failed.",
Toast.LENGTH_SHORT).show();
}
// [END_EXCLUDE]
}
}
);
}
@Override
protected void onStart() {
super.onStart();
mAuth.addAuthStateListener(firebaseAuthListener);
}
@Override
protected void onStop() {
super.onStop();
mAuth.removeAuthStateListener(firebaseAuthListener);
}
//textfield validations
private boolean validateForm() {
boolean valid = true;
String email = mEmail.getText().toString();
if (TextUtils.isEmpty(email)) {
mEmail.setError("Required.");
valid = false;
} else {
mEmail.setError(null);
}
String password = mPass.getText().toString();
if (TextUtils.isEmpty(password)) {
mPass.setError("Required.");
valid = false;
} else {
mPass.setError(null);
}
return valid;
}
}
没有弹出错误但我无法在firebase数据库中写入数据。
我已经启用了电子邮件/密码身份验证，我的规则是：
{
"rules": {
".read": "auth != null",
".write": "auth != null"
}
}
和我的build.gradle：app
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
implementation 'com.google.firebase:firebase-core:15.0.2'
implementation 'com.google.firebase:firebase-database:15.0.0'
implementation 'com.google.firebase:firebase-auth:15.1.0'
implementation 'com.google.android.gms:play-services-auth:15.0.1'
implementation 'com.github.bumptech.glide:glide:4.7.1'
implementation 'com.android.support:design:27.1.1'
annotationProcessor 'com.github.bumptech.glide:compiler:4.7.1'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
apply plugin: 'com.google.gms.google-services'

尝试将写入操作移动到成功块中。
