我在登录中有问题。基本上，我告诉你我的情况。我有两个应用程序都与一个壁炉项目连接。一个应用程序包含驱动程序登录和另一个应用程序包含客户登录当我打开客户应用并注册新客户时。客户已成功注册。然后我打开驱动程序应用程序，并输入客户凭据（客户电子邮件＆amp;密码）成功登录，并打开驱动程序活动，反之亦然。
如何解决此问题我正在使用firebase。
客户登录活动
public class CustomerLoginActivity extends AppCompatActivity {
private EditText mEmail, mPassword;
private Button mLogin, mRegistration;
private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener firebaseAuthListener;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_customer_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(CustomerLoginActivity.this, CustomerMapActivity.class);
startActivity(intent);
finish();
return;
}
}
};
mEmail = (EditText) findViewById(R.id.email);
mPassword = (EditText) findViewById(R.id.password);
mLogin = (Button) findViewById(R.id.login);
mRegistration = (Button) findViewById(R.id.registration);
mRegistration.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final String email = mEmail.getText().toString();
final String password = mPassword.getText().toString();
mAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(CustomerLoginActivity.this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if(!task.isSuccessful()){
Toast.makeText(CustomerLoginActivity.this, "sign up error", Toast.LENGTH_SHORT).show();
}else{
String user_id = mAuth.getCurrentUser().getUid();
DatabaseReference current_user_db = FirebaseDatabase.getInstance().getReference().child("Users").child("Customers").child(user_id);
current_user_db.setValue(true);
}
}
});
}
});
mLogin.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final String email = mEmail.getText().toString();
final String password = mPassword.getText().toString();
mAuth.signInWithEmailAndPassword(email, password).addOnCompleteListener(CustomerLoginActivity.this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if(!task.isSuccessful()){
Toast.makeText(CustomerLoginActivity.this, "sign in error", Toast.LENGTH_SHORT).show();
}
}
});
}
});
}
@Override
protected void onStart() {
super.onStart();
mAuth.addAuthStateListener(firebaseAuthListener);
}
@Override
protected void onStop() {
super.onStop();
mAuth.removeAuthStateListener(firebaseAuthListener);
}
}
驱动程序登录活动
public class DriverLoginActivity extends AppCompatActivity {
private EditText mEmail, mPassword;
private Button mLogin, mRegistration;
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(DriverLoginActivity.this, DriverMapActivity.class);
startActivity(intent);
finish();
return;
}
}
};
mEmail = (EditText) findViewById(R.id.email);
mPassword = (EditText) findViewById(R.id.password);
mLogin = (Button) findViewById(R.id.login);
mRegistration = (Button) findViewById(R.id.registration);
mRegistration.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final String email = mEmail.getText().toString();
final String password = mPassword.getText().toString();
mAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(DriverLoginActivity.this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if(!task.isSuccessful()){
Toast.makeText(DriverLoginActivity.this, "sign up error", Toast.LENGTH_SHORT).show();
}else{
String user_id = mAuth.getCurrentUser().getUid();
DatabaseReference current_user_db = FirebaseDatabase.getInstance().getReference().child("Users").child("Drivers").child(user_id).child("name");
current_user_db.setValue(email);
}
}
});
}
});
mLogin.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final String email = mEmail.getText().toString();
final String password = mPassword.getText().toString();
mAuth.signInWithEmailAndPassword(email, password).addOnCompleteListener(DriverLoginActivity.this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if(!task.isSuccessful()){
Toast.makeText(DriverLoginActivity.this, "sign in error", Toast.LENGTH_SHORT).show();
}
}
});
}
});
}
@Override
protected void onStart() {
super.onStart();
mAuth.addAuthStateListener(firebaseAuthListener);
}
@Override
protected void onStop() {
super.onStop();
mAuth.removeAuthStateListener(firebaseAuthListener);
}
}
我的数据库规则
firebase身份验证不会像您想做的那样区分不同的"类型"用户。您必须在应用程序中实现自己的一些自定义逻辑来处理这些情况。如果您提供正确的凭据...因此，基本signInWithEmailAndPassword()方法将始终工作...因此，您需要做的是在应用程序代码中，在调用signInWithEmailAndPassword()方法之前，请检查是否允许"允许"提供此版本的"允许"使用此版本应用...
因此，一旦您获得其用户名，在调用该标志方法之前，请向数据库进行查询，以确定该用户名是属于"客户"还是"驱动程序"。我认为您的数据库中有类似/users节点的内容 - 如果不这样做，则需要创建一个节点，无法围绕它。如果您不确定如何查询数据库，请使用addListenerForSingleValueEvent()方法...查看官方文档以获取示例/语法。
您确定了用户名是否适用于客户与驱动程序...您需要实现逻辑以决定是否允许他们继续使用Signin方法。
-
如果他们是"客户"，这是"客户"应用并向用户显示错误。
-
对于"驱动程序"应用程序类似，如果用户名返回为"驱动程序"停止代码并向用户显示错误。
