如何檢測藍牙耳機上的按鈕按

我一直試圖實現這個爲2天，現在我似乎無法找到正確的答案。我一直在尋找互聯網上的答案，並發現這一點，但他們似乎沒有幫助我：如何檢測藍牙耳機上的按鈕按

無論我怎麼努力，當我按下按鈕在我的頭上設置手機顯示音量控制，而不是被我的應用程序抓住並做一些事情。如果有人可以給我幾個提示，我會非常感謝。下面是一些代碼：

public class MediaButtonIntentReceiver extends BroadcastReceiver { 

public MediaButtonIntentReceiver() { 
    super(); 
} 

@Override 
public void onReceive(Context context, Intent intent) { 
    Log.i("test1'", "test2"); 
    String intentAction = intent.getAction(); 
    if (!Intent.ACTION_MEDIA_BUTTON.equals(intentAction)) { 
     return; 
    } 
    KeyEvent event = (KeyEvent) intent 
      .getParcelableExtra(Intent.EXTRA_KEY_EVENT); 
    if (event == null) { 
     Log.i("test3'", "test4"); 
     return; 
    } 
    int action = event.getAction(); 
    if (action == KeyEvent.ACTION_DOWN) { 
     // do something 
     Log.i("test5'", "test6"); 
    } 
    abortBroadcast(); 
} 
} 





public class MainActivity extends Activity { 

private static final String TAG = "BTAudioActivity"; 

private MediaPlayer mPlayer = null; 
private AudioManager amanager = null; 

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


    amanager = (AudioManager) getSystemService(AUDIO_SERVICE); 
    amanager.setBluetoothScoOn(true); 
    amanager.startBluetoothSco(); 
    amanager.setMode(2); 

    mPlayer = new MediaPlayer(); 

    try { 
     mPlayer.setDataSource(new FileInputStream("/sdcard/sample.wav") 
       .getFD()); 
     mPlayer.prepare(); 
     mPlayer.setVolume(8,8); 

     mPlayer.start(); 


    } catch (Exception e) { 
     Log.e(TAG, e.toString()); 
    } 




} 
    @Override 
protected void onResume() { 
    // TODO Auto-generated method stub 
MediaButtonIntentReceiver mMediaButtonReceiver = new MediaButtonIntentReceiver(); 
IntentFilter mediaFilter = new IntentFilter(Intent.ACTION_MEDIA_BUTTON); 
mediaFilter.setPriority(1000); 
registerReceiver(mMediaButtonReceiver, mediaFilter); 
    super.onResume(); 
} 

@Override 
public void onDestroy() { 
    mPlayer.stop(); 
    amanager.setMode(2); 
    amanager.setBluetoothScoOn(false); 
    super.onDestroy(); 
} 
    }

嘗試註冊在的onCreate ... 並添加使用電源管理器WAKE_LOCK this
