android - スピナーを保存し、スピナークリックからEditText入力をリロードする方法

Question

私は自分の名前を挿入するためのEditTextと、私の名前を挿入するためのEditTextを作成しました。[追加]をクリックすると、名前がスピナーに保存される必要があります。クリックすると、名前と名前が編集テキストに表示されます。このコードを作成しましたが、保存して名前のみをEditTextNameとEditTextSurnameに再読み込みします。どうすればよいですか。名前スピナーをクリックするだけで名前をリロードすることは可能ですか？これは私のコードです：

    // Spinner element
Spinner spinner;

// Add button
Button btnAdd, btnReset;

// Input text
EditText inputLabel, surname, cf, age;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    // Spinner element
    spinner = (Spinner) findViewById(R.id.spinner);

    // add button
    btnAdd = (Button) findViewById(R.id.btn_add);

    //reset Button
    btnReset =(Button) findViewById (R.id.btn_reset);

    // new label input field
    inputLabel = (EditText) findViewById(R.id.editTextName);
    surname = (EditText) findViewById(R.id.editTextSurName);
    cf = (EditText) findViewById(R.id.editTextCodicefiscale);
    age = (EditText) findViewById(R.id.editTextAge);


    // Spinner click listener
    spinner.setOnItemSelectedListener(this);

    // Loading spinner data from database
    loadSpinnerData();

    /**
     * Add new label button click listener
     * */
    btnAdd.setOnClickListener(new View.OnClickListener() {

        public void onClick(View arg0) {
            String label = inputLabel.getText().toString();
            String label2 = surname.getText().toString();

            if (label.trim().length() > 0) {
                // database handler
                DatabaseHandler db = new DatabaseHandler(
                        getApplicationContext());

                // inserting new label into database
                db.insertLabel(label);
                db.insertLabel2(label2);


                // making input filed text to blank
                inputLabel.setText("");
                surname.setText("");

                // Hiding the keyboard
                InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(inputLabel.getWindowToken(), 0);
                imm.hideSoftInputFromWindow(surname.getWindowToken(), 0);

                // loading spinner with newly added data
                loadSpinnerData();
            } else {
                Toast.makeText(getApplicationContext(), "Please enter label name",
                        Toast.LENGTH_SHORT).show();
            }

        }
    });


    btnReset.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub
            inputLabel.setText("");
            surname.setText("");
            cf.setText("");
            age.setText("");
        }
    });
}

/**
 * Function to load the spinner data from SQLite database
 * */
private void loadSpinnerData() {
    // database handler
    DatabaseHandler db = new DatabaseHandler(getApplicationContext());

    // Spinner Drop down elements
    List<String> lables = db.getAllLabels();

    // Creating adapter for spinner
    ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_spinner_item, lables);

    // Drop down layout style - list view with radio button
    dataAdapter
            .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    // attaching data adapter to spinner
    spinner.setAdapter(dataAdapter);
}

public void onItemSelected(AdapterView<?> parent, View view, int position,
        long id) {
    // On selecting a spinner item
    String label = parent.getItemAtPosition(position).toString();
    String label2 =  parent.getItemAtPosition(position).toString();
    inputLabel.setText(label);
    surname.setText(label2);
    // Showing selected spinner item
    Toast.makeText(parent.getContext(), "You selected: " + label,
            Toast.LENGTH_LONG).show();

}

public void onNothingSelected(AdapterView<?> arg0) {
    // TODO Auto-generated method stub

}

}

これは私のDatabaseHandlerです：

 // Database Version
private static final int DATABASE_VERSION = 1;

// Database Name
private static final String DATABASE_NAME = "spinnerExample";

// Labels table name
private static final String TABLE_LABELS = "labels";

// Labels Table Columns names
private static final String KEY_ID = "id";
private static final String KEY_NAME = "name";
private static final String KEY_SURNAME = "surname";


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

// Creating Tables
@Override
public void onCreate(SQLiteDatabase db) {
    // Category table create query
    String CREATE_CATEGORIES_TABLE = "CREATE TABLE " + TABLE_LABELS + "("
            + KEY_ID + " INTEGER PRIMARY KEY," + KEY_NAME + KEY_SURNAME + " TEXT)";
    db.execSQL(CREATE_CATEGORIES_TABLE);


}

// Upgrading database
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    // Drop older table if existed
    db.execSQL("DROP TABLE IF EXISTS " + TABLE_LABELS);

    // Create tables again
    onCreate(db);
}

/**
 * Inserting new lable into lables table
 * */
public void insertLabel(String label){
    SQLiteDatabase db = this.getWritableDatabase();

    ContentValues values = new ContentValues();
    values.put(KEY_NAME, label);

    // Inserting Row
    db.insert(TABLE_LABELS, null, values);
    db.close(); // Closing database connection
}

public void insertLabel2(String label2){
    SQLiteDatabase db = this.getWritableDatabase();

    ContentValues values2 = new ContentValues();
    values2.put(KEY_SURNAME, label2);

    // Inserting Row
    db.insert(TABLE_LABELS, null, values2);
    db.close(); // Closing database connection
}

/**
 * Getting all labels
 * returns list of labels
 * */
public List<String> getAllLabels(){
    List<String> labels = new ArrayList<String>();

    // Select All Query
    String selectQuery = "SELECT  * FROM " + TABLE_LABELS;

    SQLiteDatabase db = this.getReadableDatabase();
    Cursor cursor = db.rawQuery(selectQuery, null);

    // looping through all rows and adding to list
    if (cursor.moveToFirst()) {
        do {
            labels.add(cursor.getString(1));
        } while (cursor.moveToNext());
    }

    // closing connection
    cursor.close();
    db.close();

    // returning lables
    return labels;
}

}
