Question

我想在输入后告诉每个活动的标题。我已经制作了一个代码，但是当我点击按钮时它会告诉标题，因为我不知道如何在没有按钮的情况下执行此操作。

有人可以为我修改一下，这样一旦活动开启，TTS就会启动吗？

这是我的代码

public class Mode extends Activity implements
TextToSpeech.OnInitListener {

private TextToSpeech tts;
private Button btnSpeak;


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

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

    btnSpeak.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {
            speakOut("Choose your Mode");
        }

    });
}

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

@Override
public void onInit(int status) {
    // TODO Auto-generated method stub

    if (status == TextToSpeech.SUCCESS) {

        int result = tts.setLanguage(Locale.US);

        // tts.setPitch(5); // set pitch level

        // tts.setSpeechRate(2); // set speech speed rate

        if (result == TextToSpeech.LANG_MISSING_DATA
                || result == TextToSpeech.LANG_NOT_SUPPORTED) {
            Log.e("TTS", "Language is not supported");
        } else {

        }

    } else {
        Log.e("TTS", "Initilization Failed");
    }

}

private void speakOut(String text) {

    tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
}

}

使用处理程序怎么样？例如：

final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
  @Override
  public void run() {
     speakOut("Choose your Mode");  //speak after 1000ms
  }
}, 1000);

在这个例子中（在onCreate里面），它将在1000ms后执行..
