I have some issues creating a login activity. Even though I put the right username (123456) and password (123456789).
I made sure to put the getText() method inside onLogin but I always get the message "login failed" and so I assume I don't get any data from EditText, and so I can't see what's wrong. this login java class:
public class LoginActivity extends AppCompatActivity {
private EditText UsernameEt;
private EditText PasswordEt;
AlertDialog alertDialog;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
UsernameEt=findViewById(R.id.username);
PasswordEt=findViewById(R.id.password);
alertDialog = new AlertDialog.Builder(this).create();
alertDialog.setTitle("Login Status");
}
public void onLogin(View view) {
String username = UsernameEt.getText().toString();
String password = PasswordEt.getText().toString();
String type = "login";
//BackgroundWorker backgroundWorker = new BackgroundWorker(this);
//backgroundWorker.execute(type, username, password);
if(username=="123456" && password=="123456789"){
alertDialog.setMessage("Login success");
alertDialog.show();
} else {
alertDialog.setMessage("Login failed");
alertDialog.show();
}
}
}and this is the login xml:
