Question

我不知道为什么NotificationListenerService对我不起作用，看起来很简单但对我不起作用。我发现很多都没有解决我的问题。我认为我的服务已被杀死。所以我使用用于检查通知的adb

adb shell dempsys notification

它告诉我我的服务不是活的，但我不知道为什么我的服务被杀

 Notification listeners:
    All notification listeners (2) enabled for current profiles:
      ComponentInfo{com.example.user.myservicedemo/com.example.user.myservicedemo.MyListernService}
      ComponentInfo{com.meizu.battery/com.meizu.power.apps.appnotification.PermanentNotificationService}
    Live notification listeners (5):
      ComponentInfo{com.android.systemui/com.android.systemui.statusbar.phone.PhoneStatusBar} (user -1): android.service.notification.INotification

MyListernService

   public class MyListernService extends NotificationListenerService {

    private boolean mStartCompatibility ;
    public static MyListernService instance;

    @Override
    public void onCreate() {
        super.onCreate();
        Log.e("test","onCreate");
        instance = this;
        mStartCompatibility = getApplicationInfo().targetSdkVersion
                < Build.VERSION_CODES.ECLAIR;
        if (startService(new Intent(this, KeepLiveSevice.class)) == null)
            throw new RuntimeException("Couldn't find " + KeepLiveSevice.class.getSimpleName());
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.e("test","onStartCommand");
        toggleNotificationListenerService();
        return mStartCompatibility ? START_STICKY_COMPATIBILITY : START_STICKY;
    }

    @Override
    public void onNotificationPosted(StatusBarNotification sbn) {
        super.onNotificationPosted(sbn);
        Log.e("test","onNotificationPosted");
    }

    @Override
    public void onNotificationRemoved(StatusBarNotification sbn) {
        super.onNotificationRemoved(sbn);
        Log.e("test","onNotificationRemoved");
    }

    @Override
    public void onListenerConnected() {
        super.onListenerConnected();
        Log.e("test","onListenerConnected");
    }

    @Override
    public void onListenerDisconnected() {
        super.onListenerDisconnected();
        Log.e("test","onListenerDisconnected");
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        instance = null;
        Log.e("test","onDestroy");
    }

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

    private void toggleNotificationListenerService() {
        PackageManager pm = getPackageManager();
        pm.setComponentEnabledSetting(new ComponentName(this, com.example.user.myservicedemo.MyListernService.class),
                PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);

        pm.setComponentEnabledSetting(new ComponentName(this,com.example.user.myservicedemo.MyListernService.class),
                PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);

    }
}

和MainActivity

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        if(!isNotificationListenerEnabled(this)){
            openNotificationListenSettings();
        }
        startService(new Intent(this,MyListernService.class));
    }

    public boolean isNotificationListenerEnabled(Context context) {
        Set<String> packageNames = NotificationManagerCompat.getEnabledListenerPackages(this);
        if (packageNames.contains(context.getPackageName())) {
            return true;
        }
        return false;
    }

    public void openNotificationListenSettings() {
        try {
            Intent intent;
            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP_MR1) {
                intent = new Intent(Settings.ACTION_NOTIFICATION_LISTENER_SETTINGS);
            } else {
                intent = new Intent("android.settings.ACTION_NOTIFICATION_LISTENER_SETTINGS");
            }
            startActivity(intent);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

keepLiveService

public class KeepLiveSevice extends Service {


    @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN_MR2)
    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        if (MyListernService.instance == null)
            throw new RuntimeException(MyListernService.class.getSimpleName() + " not running");

        //Set both services to foreground using the same notification id, resulting in just one notification
        startForeground(MyListernService.instance);
        startForeground(this);

        //Cancel this service's notification, resulting in zero notifications
        stopForeground(true);

        //Stop this service so we don't waste RAM.
        //Must only be called *after* doing the work or the notification won't be hidden.
        stopSelf();
        return START_NOT_STICKY;
    }
    private static final int NOTIFICATION_ID = 10;

    private static void startForeground(Service service) {
        Notification notification = new Notification.Builder(service).getNotification();
        service.startForeground(NOTIFICATION_ID, notification);
    }

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

的AndroidManifest.xml

  <service android:name=".MyListernService"
            android:label="@string/app_name"
            android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
            <intent-filter>
                <action android:name="android.service.notification.NotificationListenerService" />
            </intent-filter>
        </service>
       <service android:name=".KeepLiveSevice"/>

Answer 1

您必须授予对应用通知的访问权限。

基本上转到手机的设置＆gt;然后，通知会授权您的应用访问通知

NotificationListenerService不调用onNotificationPosted或onNotificationRemoved
