安卓：说话失败：不绑定到TTS引擎

问题描述

我有一个简单的应用程序即能说话。

I have a simple app that is able to speak.

的东西是我在logcat中得到这个错误：

The things is I got this error in logcat:

TextToSpeech Sucessfully bound to com.ivona.tts
TextToSpeech speak failed : not bound to TTS engine

我加什么特别的Andr​​oid清单，确实有？

I add nothing particular in the Android manifest, do have to ?

code

import java.util.Locale;

import android.app.Activity;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;
import android.util.Log;

public class Main extends Activity implements OnInitListener{

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

    tts = new TextToSpeech(this, this);

    tts.speak("Hello World", TextToSpeech.QUEUE_FLUSH, null);
}

@Override
protected void onDestroy() {
    MyTTS.release();
    super.onDestroy();
}

@Override
public void onInit(int status) {
    if (status == TextToSpeech.SUCCESS) {
        tts.setLanguage(Locale.getDefault());
    } else {
        Log.e("TTS", "Initialization failed");
    }

}

}

我不知道为什么这个错误发生时。
谁能帮我？
预先感谢

I don't know why this error occurs.Can anyone help me?Thank in advance

编辑：我不想把speak方法里面的OnInit方法。我该怎么办呢？

Edit : I don't want put the speak method Inside the onInit method. How can I do it ?

推荐答案

您只能让发动机说话，OnInit的完成后，所以做你的OnInit（）如下：

You can only let the engine speak, after onInit is done, so do following in You onInit():

   if (status == TextToSpeech.SUCCESS) {
     tts.speak("Hello World", TextToSpeech.QUEUE_FLUSH, null);

   }
