我有一个服务,我试图启动TextToSpeech引擎,但似乎它不起作用,所以是否可以从服务启动tts?
这是我尝试过的:
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
}
}
答案 0 :(得分:4)
new TextToSpeech(getApplicationContext(),this);
和我一起工作...... 但是一定要让服务运行,直到发言完毕。
