Question

在我的应用中，我希望用户可以通过蓝牙、耳机和扬声器收听音频，因此我提供了一个微调器，如果连接了蓝牙，则微调器添加蓝牙，同时连接耳机，微调器也添加耳机。

>

但是当我在具体启动服务以注册蓝牙和耳机广播接收器时并运行应用程序，即使设备未连接到蓝牙和耳机设备或从它们中拔出，我也会让耳机从耳机广播接收器中拔出动作。

创建

 startService(Intent(this, HeadsetService::class.java))
        if (AppUtils.isBluetoothSupported(packageManager)) {
            startService(Intent(this, BluetoothService::class.java))
        }

破坏

stopService(Intent(this, HeadsetService::class.java))
        stopService(Intent(this, BluetoothService::class.java))

耳机服务

public class HeadsetService extends Service {
    private HeadsetUtility mHeadsetUtility;

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

    public void onCreate() {
        super.onCreate();
        initHeadsetBroadcastReceiver();
    }

    public void onDestroy() {
        stopHeadsetBroadcastReceiver();
        super.onDestroy();
    }

    private void initHeadsetBroadcastReceiver() {
        if (this.mHeadsetUtility == null) {
            this.mHeadsetUtility = new HeadsetUtility();
            Log.e("videocall","headsetservice");
            registerReceiver(this.mHeadsetUtility, HeadsetUtility.getIntentFilter());
        }
    }

    private void stopHeadsetBroadcastReceiver() {
        HeadsetUtility headsetUtility = this.mHeadsetUtility;
        if (headsetUtility != null) {
            unregisterReceiver(headsetUtility);
        }
    }
}

耳机广播

public final class HeadsetUtility extends BroadcastReceiver {
    private static final String TAG = "HTEventReceiver";
    private static boolean isHeadsetPluggedIn = false;

    public static IntentFilter getIntentFilter() {
        return new IntentFilter(Intent.ACTION_HEADSET_PLUG);
    }

    public static boolean isIsHeadsetPluggedIn() {
        return isHeadsetPluggedIn;
    }

    public static void setIsHeadsetPluggedIn(boolean z) {
        isHeadsetPluggedIn = z;
    }

    public void onReceive(Context context, Intent intent) {
        if (intent.getAction() == null) {
        } else if (intent.getAction().equals(Intent.ACTION_HEADSET_PLUG)) {
            int intExtra = intent.getIntExtra("state", -1);
            switch (intExtra) {
                case 0:
                    headsetIsPluggedOut();
                    return;
                case 1:
                    headsetIsPluggedIn();
                    return;
                default:
                    setIsHeadsetPluggedIn(false);
                    return;
            }
        }
    }

    private void headsetIsPluggedIn() {
        setIsHeadsetPluggedIn(true);
        AppUtils.setmAudioSource(AppUtils.AudioSource.HEADSET);
        Log.e("videocall","headsetservice1");
        RxBus.publish(new RxEvent.EventAudioBroadcast(new Event_AudioSource(AppUtils.AudioSource.HEADSET,1)));
    }

    private void headsetIsPluggedOut() {
        setIsHeadsetPluggedIn(false);
        if (BluetoothUtility.isIsBluetoothConnected()) {
            AppUtils.setmAudioSource(AppUtils.AudioSource.BLUETOOTH);
        } else {
            AppUtils.setmAudioSource(AppUtils.AudioSource.SPEAKER);
        }
        Log.e("videocall","headsetservice2");
        RxBus.publish(new RxEvent.EventAudioBroadcast(new Event_AudioSource(AppUtils.AudioSource.HEADSET,2)));
    }
}

清单

 <service android:name=".utils.BluetoothService" />
        <service android:name=".utils.HeadsetService" />

在清单中我没有注册广播，我已经使用意图过滤器注册了广播

所以，我的问题是当应用程序启动时服务启动并注册广播，我从广播中拔出耳机并调用耳机IsPluggedOut（），即使设备未连接到蓝牙和耳机设备或拔出来自他们

请提出建议

请查看 this 帖子。有一个获取耳机连接事件的示例。希望这可能会有所帮助。
