SQLite Android虽然在数据库中添加新客户但没有任何反应

Question

我遇到这样的问题：

我有新客户的注册表，但他填写了所有字段，如登录，密码等。 Base SQL中没有任何事情发生。

我不明白我的错误。

switch (v.getId()) {
    case R.id.create_account:

        database = dbHelper.getWritableDatabase();

        contentValues = new ContentValues();

        // AlertDialog Registration
        View viewInflated = LayoutInflater.from(this).inflate(R.layout.registration_form, (ViewGroup) findViewById(android.R.id.content), false);
        inputPassword = (EditText) viewInflated.findViewById(R.id.input_password);
        inputLogin = (EditText) viewInflated.findViewById(R.id.input_login);
        inputEmail = (EditText) viewInflated.findViewById(R.id.input_email);

        builder.setView(viewInflated);

        builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                String login = inputLogin.getText().toString();
                String email = inputEmail.getText().toString();
                String password = inputPassword.getText().toString();

                // Передаем с помошью КонтентВелью наши значения из полей
                contentValues.put(DBHelper.KEY_NAME, login);
                contentValues.put(DBHelper.KEY_EMAIL, email);
                contentValues.put(DBHelper.KEY_PASSWORD, password);

                // Записываем в базу ТейблКонтакты
                database.insert(DBHelper.TABLE_CONTACTS, null, contentValues);

                database.close();
                Toast toast = Toast.makeText(getApplicationContext(), "Вы зарегистрированы", Toast.LENGTH_LONG);
               toast.show();
               dialog.cancel();
            }
        });

我的DBHelper

public class DBHelper extends SQLiteOpenHelper {

    public static final int DATABASE_VERSION = 1;
    public static final String DATABASE_NAME = "contactDb";
    public static final String TABLE_CONTACTS = "contacts";

    public static final String KEY_ID = "_id";
    public static final String KEY_NAME = "name";
    public static final String KEY_PASSWORD = "password";
    public static final String KEY_EMAIL = "email";

    public DBHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        db.execSQL("create table " + TABLE_CONTACTS + "(" + KEY_ID + " integer primary key," + KEY_NAME + " text," + KEY_PASSWORD + " text" + KEY_EMAIL + " text" + ")");

    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        db.execSQL("drop table if exists " + TABLE_CONTACTS);

        onCreate(db);

    }
}
