Android蓝牙断开连接

Question

我有一段代码可以检测我是否正在接听电话，然后我的应用停止播放音乐并继续播放。如果任何蓝牙设备与我的设备断开连接，我想做同样的事情，我希望它也停止播放。我不知道从哪里开始，请帮助我。谢谢。

这是我的来电代码：

PhoneStateListener phoneStateListener = new PhoneStateListener() {

    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
        switch (state){ 

        case TelephonyManager.CALL_STATE_IDLE:                      
               //CALL_STATE_IDLE;
            if (audioOncall) {
                resetMetadata();
                UpdatetoLogo();
                Intent restart = new Intent(getApplicationContext(), MainActivity.class);

                startActivity(restart);
            }
            break;
        case TelephonyManager.CALL_STATE_OFFHOOK:
               //CALL_STATE_OFFHOOK;
            if (audioOncall) {
                resetMetadata();
                UpdatetoLogo();
                Intent restart = new Intent(getApplicationContext(), MainActivity.class);

                startActivity(restart);
            }
            break;
        case TelephonyManager.CALL_STATE_RINGING:
               //CALL_STATE_RINGING
            audioOncall = audioSignal.isPlaying();
            stopOncall();
                break;
           default:
                break;


        }
        super.onCallStateChanged(state, incomingNumber);
    }
};

我已经设法让蓝牙工作了，但是它没有听取更改活动，它只接收应用程序加载时的状态...如何更改以下代码以使其听对于bluetooth活动中的更改？

public void onCreate() {

    IntentFilter filter1 = new IntentFilter(BluetoothDevice.ACTION_ACL_CONNECTED);
    IntentFilter filter2 = new IntentFilter(BluetoothDevice.ACTION_ACL_DISCONNECT_REQUESTED);
    IntentFilter filter3 = new IntentFilter(BluetoothDevice.ACTION_ACL_DISCONNECTED);
    this.registerReceiver(mReceiver, filter1);
    this.registerReceiver(mReceiver, filter2);
    this.registerReceiver(mReceiver, filter3);
}

//The BroadcastReceiver that listens for bluetooth broadcasts
private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

        if (BluetoothDevice.ACTION_FOUND.equals(action)) {
           //Device found
        }
        else if (BluetoothDevice.ACTION_ACL_CONNECTED.equals(action)) {
            //Device is now connected
            stopOncall();

            resetMetadata();
            UpdatetoLogo();
            Intent restart = new Intent(getApplicationContext(), MainActivity.class);

            startActivity(restart);
        }
        else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) {
            //Done searching
        }
        else if (BluetoothDevice.ACTION_ACL_DISCONNECT_REQUESTED.equals(action)) {
           //Device is about to disconnect
            stopOncall();
        }
        else if (BluetoothDevice.ACTION_ACL_DISCONNECTED.equals(action)) {
           //Device has disconnected
            stopOncall();
        }           
    }
};
