断开语音识别服务

标签: android speech-recognition destroy

如果我使用这样的语音识别

Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);

做一些设定...... 并制作

startActivityForResult(intent, SystemData.VOICE_RECOGNITION_REQUEST_CODE);

有没有办法使用某种意图或以任何其他方式停止服务(如销毁)?

我找到了如何停止语音识别服务。 我创建了一个SpeechRecognizer类型的通用变量。

把它放在课程的开头,如:

私人SpeechRecognizer speech = null;

然后在语音初始化中,我将它连接到一个监听器并在意图中使用它:

    speech = SpeechRecognizer.createSpeechRecognizer(getActivity());

    speech.setRecognitionListener(this);

    Intent recognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);

然后在本课程的任何部分,如果我想激活演讲,我就用这个:

speech.startListening(recognizerIntent);

并阻止它我这样做:

speech.stopListening();

所以听众是言语活动的关键。

首先将两个按钮[buttonStart和buttonStop]添加到您的活动xml然后再添加 在包含您问题中的代码的活动中添加:    @覆盖       public void onCreate(Bundle savedInstanceState){         super.onCreate(savedInstanceState);         的setContentView(R.layout.main);

    buttonStart = (Button) findViewById(R.id.buttonStart);
    buttonStop = (Button) findViewById(R.id.buttonStop);

    buttonStart.setOnClickListener(this);
    buttonStop.setOnClickListener(this);
  }

  public void onClick(View src) {
    switch (src.getId()) {
    case R.id.buttonStart:
      Log.d(TAG, "onClick: starting srvice");
      startService(new Intent(this, MyService.class));
      break;
    case R.id.buttonStop:
      Log.d(TAG, "onClick: stopping srvice");
      stopService(new Intent(this, MyService.class));
      break;
    }
  }

MyService.java

mport android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
import android.util.Log;
import android.widget.Toast;

public class MyService extends Service {
    private static final String TAG = "MyService";
    MediaPlayer player;

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate() {
        Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show();
        Log.d(TAG, "onCreate");

        player = MediaPlayer.create(this, R.raw.braincandy);
        player.setLooping(false); // Set looping
    }

    @Override
    public void onDestroy() {
        Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();
        Log.d(TAG, "onDestroy");
        player.stop();
    }

    @Override
    public void onStart(Intent intent, int startid) {
        Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show();
        Log.d(TAG, "onStart");
        player.start();
    }
}
