Question

我最近购买了蓝牙耳机http://www.plantronics.com/middle-east/product/ml20，并且一直试图按下呼叫按钮以触发识别器内容。但到目前为止，我的所有尝试都失败了。考虑到我的耳机可能很古怪并且没有按预期运行，我试图拦截触摸耳机长按时手机上的语音拨号器的任何动作，再次导致失败。下面是我正在使用的代码，根据我读过的所有其他线程应该正常工作。我错过了什么吗？ ACTION_VOICE_COMMAND不是触发语音拨号器的原因吗？

private MediaButtonIntentReceiver receiver = new MediaButtonIntentReceiver();
private IntentFilter filter1 = new IntentFilter(Intent.ACTION_VOICE_COMMAND);
private IntentFilter filter2 = new IntentFilter(Intent.ACTION_CALL_BUTTON);
private IntentFilter filter3 = new IntentFilter(Intent.ACTION_MEDIA_BUTTON);
private IntentFilter filter4 = new IntentFilter(Intent.ACTION_POWER_DISCONNECTED);

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

    speech_text = (EditText) findViewById(R.id.voiceInput);

    filter1.setPriority(100000);
    filter2.setPriority(100000);
    filter3.setPriority(100000);
    filter4.setPriority(100000);

    this.registerReceiver(receiver, filter1);
    this.registerReceiver(receiver, filter2);
    this.registerReceiver(receiver, filter3);
    this.registerReceiver(receiver, filter4);
}


public class MediaButtonIntentReceiver extends BroadcastReceiver {

public MediaButtonIntentReceiver() {
    super();
}

@Override
public void onReceive(Context context, Intent intent) {
    /*String intentAction = intent.getAction();
    if (!Intent.ACTION_MEDIA_BUTTON.equals(intentAction)) {
        return;
    }
    KeyEvent event = (KeyEvent)intent.getParcelableExtra(Intent.EXTRA_KEY_EVENT);
    if (event == null) {
        return;
    }
    int action = event.getAction();
    if (action == KeyEvent.ACTION_DOWN) {
        // do something*/
        Toast.makeText(context, "BUTTON PRESSED!", Toast.LENGTH_LONG).show(); 
        Log.v("TEST", "I am logging something informational!"); 
    //}
    //abortBroadcast();
}

}
