如何将android spinner选中的值存储到parse.com？

Question

我想将android spinner选中的值存储到parse.com，在那里我创建了另一个列名作为分支。因此，每当任何用户注册并从下拉菜单中选择任何项目时，它将作为修复字符串存储到分支列名称中。 这是我的注册活动代码。

package com.goyllo.gecrajkot;
import android.app.AlertDialog;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.internal.widget.AdapterViewCompat;
import android.view.View;
import android.view.Window;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Spinner;

import com.parse.ParseException;
import com.parse.ParseUser;
import com.parse.SignUpCallback;


public class SignUp extends ActionBarActivity implements      AdapterView.OnItemSelectedListener {



protected EditText mUsername;
protected EditText mPassword;
protected EditText mEmail;
protected Button mSignUpButton;
protected Spinner mSpinnerBranch;

@Override
protected void onCreate(Bundle savedInstanceState) {
    requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_sign_up);


    mUsername = (EditText)findViewById(R.id.UsernameField);
    mPassword =(EditText)findViewById(R.id.PasswordField);
    mEmail =(EditText)findViewById(R.id.EmailField);
    mSpinnerBranch = (Spinner)findViewById(R.id.spinner_branch);


    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
            R.array.branch_array, android.R.layout.simple_spinner_item);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    mSpinnerBranch.setAdapter(adapter);


    mSignUpButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String username = mUsername.getText().toString();
            String password = mPassword.getText().toString();
            String email = mEmail.getText().toString();


            username = username.trim();
            password = password.trim();
            email = email.trim();

            if(username.isEmpty() || password.isEmpty() || email.isEmpty()){
                AlertDialog.Builder builder = new AlertDialog.Builder(SignUp.this);
                builder.setMessage(R.string.signup_error_message)
                 .setTitle(R.string.signup_error_title)
                 .setPositiveButton(android.R.string.ok, null);
                AlertDialog dialog = builder.create();
                dialog.show();
            }
            else{
                // create the new user
                setProgressBarIndeterminateVisibility(true);
                ParseUser newUser = new ParseUser();
                newUser.setUsername(username);
                newUser.setPassword(password);
                newUser.setEmail(email);
                newUser.put("branch", SelectedBranch);


                newUser.signUpInBackground(new SignUpCallback() {
                    @Override
                    public void done(ParseException e) {
                        setProgressBarIndeterminateVisibility(false);
                        if (e == null) {
                            //success!

                            Intent intent = new Intent(SignUp.this, MainActivity.class);
                            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                            intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
                            startActivity(intent);

                        } else {
                            AlertDialog.Builder builder = new AlertDialog.Builder(SignUp.this);
                            builder.setMessage(e.getMessage())
                                    .setTitle(R.string.signup_error_title)
                                    .setPositiveButton(android.R.string.ok, null);
                            AlertDialog dialog = builder.create();
                            dialog.show();
                        }
                    }
                });
            }
}

public void onItemSelected(AdapterView<?> parent, View view,
                                   int pos, long id) {
            // An item was selected. You can retrieve the selected item using
           String SelectedBranch = parent.getItemAtPosition(pos).toString();
        }

        public void onNothingSelected(AdapterView<?> parent) {
            // Another interface callback
        }

    });
}

我的下线代码有问题。不知道我做错了什么。或者如果您有任何其他建议，请在此处描述。

newUser.put（＆＃34; branch＆＃34;，SelectedBranch）;
