android - 将 Spinner 添加到设计器后如何在 Eclipse Android 中使用它？

Question

package com.testotspeech;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.Locale;

import android.app.Activity;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.util.Log;
import android.view.View;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Spinner;

public class AndroidTestToSpeechActivity extends Activity implements
        TextToSpeech.OnInitListener {
    /** Called when the activity is first created. */

    private TextToSpeech tts;
    private Button btnSpeak;
    private EditText txtText;
    private ArrayList<String> itemsList;
    private Spinner spinner;
    private String contry_name;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Log.i("----------",Arrays.toString(Locale.getAvailableLocales()));
        itemsList = new ArrayList<String>();
        itemsList.add(Arrays.toString(Locale.getAvailableLocales()));
        spinner = (Spinner)findViewById(R.id.spinner1);
        ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,itemsList);
        dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner.setAdapter(dataAdapter);

        contry_name=String.valueOf(spinner.getSelectedItem());
        System.out.println(contry_name);


        tts = new TextToSpeech(this, this);
        btnSpeak = (Button) findViewById(R.id.btnSpeak);
        txtText = (EditText) findViewById(R.id.txtText);

        // button on click event
        btnSpeak.setOnClickListener(new View.OnClickListener() {

            public void onClick(View arg0) {
                speakOut();
            }

        });
    }

    @Override
    public void onDestroy() {
        // Don't forget to shutdown tts!
        if (tts != null) {
            tts.stop();
            tts.shutdown();
        }
        super.onDestroy();
    }

    public void onInit(int status) {

        if (status == TextToSpeech.SUCCESS) {

            int result = tts.setLanguage(Locale.);

我有一些问题。在运行应用程序时，在我做出任何选择之前，首先在微调器中我看到所有这样的项目:[en, en_AU, en_BE,en_BW...等等。我希望当我单击微调器的向下箭头时，我会一个接一个地看到一行中的所有项目，当我选择其中一个项目时，它将用作 LOCALE

所以我需要以某种方式解决这个问题。

第二件事是在 int result = tts.setLanguage(Locale.); 中选择项目时如何使用 contry_name 字符串？

现在是:int result = tts.setLanguage(Locale.ENGLISH);但我希望它成为从微调器中选择的项目。
