Я не могу записать какие-либо данные в базу данных Firebase, но она подключена. Мои правила чтения и записи установлены в true, и я добавил требуемые SDK, но все еще не могу добавить данные.
Button RegisterBttn;
EditText userEmail, userPassword, userName;
//Firebase setup
FirebaseDatabase mydatabase;
DatabaseReference users;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register_page);
RegisterBttn = (Button) findViewById(R.id.registerBttn);
//Firebase
mydatabase = FirebaseDatabase.getInstance();
users = mydatabase.getReference("Users");
userEmail = (EditText) findViewById(R.id.emailRegisterText);
userPassword = (EditText) findViewById(R.id.passwordRegisterText);
userName = (EditText) findViewById(R.id.nameRegisterText);
RegisterBttn.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v){
final User user = new User(userName.getText().toString(),
userPassword.getText().toString(),
userEmail.getText().toString());
users.addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
if(dataSnapshot.child(user.getUserName()).exists()) {
Toast.makeText(RegisterPage.this, "The Username already exists", Toast.LENGTH_SHORT).show();
}
else{
users.child(user.getUserName()).setValue(user);
// Log.i("Info", "Button Pressed");
Toast.makeText(RegisterPage.this, "Registered successfully", Toast.LENGTH_SHORT).show();
}
}
@Override
public void onCancelled(@NonNull DatabaseError databaseError) {
// Toast.makeText(RegisterPage.this, "Error registering", Toast.LENGTH_SHORT).show();
}
});
}
});
}
}
У меня есть отдельный класс для «Пользователь», содержащий имя пользователя, пароль и адрес электронной почты. , Я использую Realtime DB. Правила:
{
"rules": {
".read": true,
".write": true
}
}
