Sign Up screen with Parse.com Android Studio

Question

I'm an Android student and I'm trying to set up a Sign Up screen and save the user in parse.com but when I click on Sign Up button gives me error and I don't know why. Also I don't know how to test if the password and repeat password editable texts are the same.

public void onCreate (Bundle saveInstanceState) {
        super.onCreate(saveInstanceState);
        setContentView(R.layout.signupscreen);

        Button signup = (Button) findViewById(R.id.signup);

        signup.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {


                String username = String.valueOf(findViewById(R.id.username_edittext));
                String password = String.valueOf(findViewById(R.id.password_edittext));
                String repassword = String.valueOf(findViewById(R.id.repassword_edittext));
                String email = String.valueOf(findViewById(R.id.email_edittext));
                String universitat = String.valueOf(findViewById(R.id.universitat_edittext));
                String carrera = String.valueOf(findViewById(R.id.carrera_edittext));


                // Force user to fill up the form
                if (username.equals("") && password.equals("")) {
                    Toast.makeText(getApplicationContext(),
                            "Please complete the sign up form",
                            Toast.LENGTH_LONG).show();

                } else {
                    // Save new user data into Parse.com Data Storage
                    ParseUser user = new ParseUser();
                    user.setUsername(username);
                    user.setPassword(password);
                    user.setEmail(email);
                    // Introduir universitat i carrera d'una llista de la DB sincronitzada amb Parse
                    //user.put("carrera", carrera);
                    //user.put("universitat", universitat);

                    Log.v("username: ", username);
                    Log.v("password: ", password);
                    Log.v("email: ", email);

                    user.signUpInBackground(new SignUpCallback() {

                        @Override
                        public void done(com.parse.ParseException e) {
                            if (e == null) {
                                // Show a simple Toast message upon successful registration
                                Toast.makeText(getApplicationContext(),
                                        "Successfully Signed up, please log in.",
                                        Toast.LENGTH_LONG).show();
                            } else {
                                Toast.makeText(getApplicationContext(),
                                        "Sign up Error", Toast.LENGTH_LONG)
                                        .show();
                            }
                        }
                    });
                }

            }
        });
    }

Answer 1

As I mentioned above, usually you would use something like

findViewById(R.id.username_edittext).getText().toString()

to get an EditText 's value.
