Parse.com：使用parseUser，如何在我从类中解析创建的列中保存数据？

Question

I am using Android Studio for my app and Parse for my database... and on the create an account page I have, it allows the user to enter in first name, last name, email, username, and password.

But my code is using parseUser... I don't know how to set the first and last name in the database. I know setUsername, setPassword, setEmail is a part of it... but what about if you make a column in Parse? How can you add this in your class?

This is a part of my code, what it looks like...my problem is in the else statement I have:

          // Force user to fill up the form
            if (usernametxt.equals("") && passwordtxt.equals("") && emailtxt.equals("")) {
                Toast.makeText(getApplicationContext(),
                        "Please fill in the username, password, and email fields.",
                        Toast.LENGTH_LONG).show();

            } else {
                // Save new user data into Parse.com Data Storage
                ParseUser user = new ParseUser();

                //somehow save first and last name 

                user.setEmail(emailtxt);
                user.setUsername(usernametxt);
                user.setPassword(passwordtxt);
                user.signUpInBackground(new SignUpCallback() {
                    public void done(ParseException e) {
                        if (e == null) {

Yes, Parse does provide methods to save username, passwords like setUsername(params) and setPassword(params) but if you want to add more data to the tables, you can create more columns according to your needs as I did in this code snippet.

If you have come columns created already in parse back-end like name, phone,address,cityState,companyId, this is how I am doing it.

private void savetoParse() {

        ParseUser user = new ParseUser();
        user.setUsername(usernameEditText.getText().toString());
        user.setPassword(passEditText.getText().toString());
        user.put("name", nameEditText.getText().toString());
        user.setEmail(emailEditText.getText().toString());
        user.put("phone", phoneNoEditText.getText().toString());
        user.put("address", addressEditText.getText().toString());
        user.put("cityState", cityStateEditText.getText().toString());
        user.put("companyID", compSchoolIdEditText.getText().toString());

        user.signUpInBackground(new SignUpCallback() {

            @Override
            public void done(ParseException e) {

                if (e != null) {

                    Toast.makeText(SignupActivityUpdate.this,
                            "Saving user failed.", Toast.LENGTH_SHORT).show();
                    Log.w(TAG,
                            "Error : " + e.getMessage() + ":::" + e.getCode());

                    if (e.getCode() == 202) {

                        Toast.makeText(
                                SignupActivityUpdate.this,
                                "Username already taken. \n Please choose another username.",
                                Toast.LENGTH_LONG).show();
                        usernameEditText.setText("");
                        passEditText.setText("");
                        confirmPassEditText.setText("");

                    }

                } else {

                    Toast.makeText(SignupActivityUpdate.this, "User Saved",
                            Toast.LENGTH_SHORT).show();

                    /*Do some things here if you want to.*/

                }

            }
        });

NOTE : The first params is the column name and second is the value. So, it basically acts like a key value pair.

This is solve the problem..lemme know if this works..good luck..:)

/**
     * user Registration here
     * save user registration value on server here
     */
    private void userRegistration()
    {
        progressDialog=new ProgressDialog(SignUpThirdPage.this);

        user.setPassword(strPassword);
        user.setEmail(strEmailId);
        // surName column create on parse.com db you can check after run that code
        // like that u can add more column in signup table
