我已经从那里我试图启动一个TextToSpeech引擎服务，但它似乎不工作，所以是有可能从服务开始TTS？

这是我已经试过：

 包com.example.TextSpeaker;

进口java.util.Locale中;
进口android.app.Service;
进口android.content.Intent;
进口android.os.IBinder;
 进口android.speech.tts.TextToSpeech;
进口android.speech.tts.TextToSpeech.OnInitListener;
进口android.util.Log;
进口android.widget.Toast;


 公共类SpeakerService扩展服务实现OnInitListener {

   公共静态TextToSpeech MTTS;
  @覆盖
   公众的IBinder onBind（意向为arg0）{
 // TODO自动生成方法存根
  返回null;
  }

@覆盖
 公共无效的onCreate（）{
Log.d（SpeakerService，服务创建成功！）;
MTTS =新TextToSpeech（这一点，这一点）;
mtts.setLanguage（Locale.ENGLISH）;


}
@覆盖
公共无效ONSTART（意向意图，诠释startid）
  {
Log.d（SpeakerService，服务启动成功！）;
 Log.d（SpeakerService，服务启动成功！）;
  Log.d（SpeakerService，tspker.mtts =+ TextSpeaker.mtts.toString（））;
 MTTS =新TextToSpeech（这一点，这一点）;
   mtts.setLanguage（Locale.ENGLISH）;
   mtts.speak（Receiver.str，TextToSpeech.QUEUE_FLUSH，NULL）;
}
 @覆盖
 公共无效的onDestroy（）{
 如果（MTTS！= NULL）
  {
     mtts.stop（）;
  Toast.makeText（getApplicationContext（），服务已被摧毁！，T oast.LENGTH_SHORT）.show（）;
}

}

 @覆盖
  公共无效的OnInit（INT为arg0）{
   // TODO自动生成方法存根

 }

}
 

解决方案

新TextToSpeech（getApplicationContext（），这一点）;

可与我... 但可以肯定，让服务运行，直到语音完成。

i have a service from where i am trying to start a TextToSpeech engine ,but it seems that it's not working , so is it possible to start tts from a service?

here's what i've tried:

package com.example.TextSpeaker;

import java.util.Locale;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
 import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;
import android.util.Log;
import android.widget.Toast;


 public class SpeakerService extends Service implements OnInitListener{

   public static TextToSpeech mtts;
  @Override
   public IBinder onBind(Intent arg0) {
 // TODO Auto-generated method stub
  return null;
  }

@Override
 public void onCreate(){
Log.d("SpeakerService","Service created successfully!");
mtts = new TextToSpeech(this,this);
mtts.setLanguage(Locale.ENGLISH);


}
@Override
public void onStart(Intent intent,int startid)
  {
Log.d("SpeakerService","Service started successfully!");
 Log.d("SpeakerService","Service started successfully!");
  Log.d("SpeakerService","tspker.mtts = " + TextSpeaker.mtts.toString());
 mtts = new TextToSpeech(this,this);
   mtts.setLanguage(Locale.ENGLISH);
   mtts.speak(Receiver.str, TextToSpeech.QUEUE_FLUSH,null);
}
 @Override
 public void onDestroy(){
 if(mtts!=null)
  {
     mtts.stop();
  Toast.makeText(getApplicationContext(),"The service has been destroyed!", T  oast.LENGTH_SHORT).show();
}

}

 @Override
  public void onInit(int arg0) {
   // TODO Auto-generated method stub

 }

}

new TextToSpeech(getApplicationContext(),this);

works with me... But be sure to let the service run , until speech is done..
