安卓通知栏按钮变得不响应

Question

我正在开发一个应用程序，其中有一个服务应该始终在后台运行。此服务负责显示一个始终可见的通知栏。通知栏有两个按钮，第一个按钮用于获取并存储一些数据，第二个按钮应该打开一个活动，以显示所有的数据。我遇到了一个问题，当我关闭应用程序然后按下通知按钮以启动一个活动后，我的通知按钮停止响应。请注意，在第二个按钮单击开始活动之前，两个按钮都可以正常工作。

这是我的通知服务和通知栏按钮处理程序的模板代码：

处理通知栏的服务：

   public class NotificationBarService extends Service {

        private int notificationID;


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

        @Override
        public int onStartCommand(Intent intent, int flags, int startId){


            notificationID = new Random().nextInt();

            RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification);
            contentView.setImageViewResource(R.id.image, R.mipmap.ic_launcher);
            contentView.setTextViewText(R.id.title, "Custom notification");
            contentView.setTextViewText(R.id.text, "This is a custom layout");


            //Handle the button for showing bookmarks on custom notification
            Intent buttonsIntent2 = new Intent(this, NotificationBarButtonActivityHandler.class);
            buttonsIntent2.putExtra(PENDING_ACTION, SHOW_BOOKMARKS);
            contentView.setOnClickPendingIntent(R.id.notificationBarShowBookmarksButton, PendingIntent.getActivity(this, 0, buttonsIntent2, 0));


            //Handle the button for adding bookmark on custom notification
            Intent buttonsIntent = new Intent(this, NotificationBarButtonActivityHandler.class);
            buttonsIntent.putExtra(PENDING_ACTION, REGISTER_BOOKMARK);
            contentView.setOnClickPendingIntent(R.id.notificationBarAddBookmarkFromChromeButton, PendingIntent.getActivity(this, 1, buttonsIntent, 0));


            RemoteViews notificationView = new RemoteViews(getPackageName(),
                    R.layout.custom_notification);


            Intent switchIntent = new Intent(this, NotificationBarService.class);
            PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 0,
                    switchIntent, 0);

            notificationView.setOnClickPendingIntent(R.id.notificationBarShowBookmarksButton,
                    pendingSwitchIntent);


            NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
                    .setContent(contentView)
                    .setSmallIcon(R.drawable.notification_small_icon)
                    .setOngoing(true);

            Notification notification = mBuilder.build();

            startForeground(notificationID, notification);

            return START_STICKY;
        }


        @Override
        public void onDestroy(){
            super.onDestroy();

            stopForeground(true);

        }
    }

处理通知栏上按钮按下的类

public class NotificationBarButtonActivityHandler extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        String action = (String) getIntent().getExtras().get(NotificationBarService.PENDING_ACTION);

        if (action != null) {
            if (action.equals(NotificationBarService.REGISTER_BOOKMARK)){
                CustomLogger.log("---------------- BUTTON FOR COLLECT DATA WAS PRESSED!!!");

                //Does something here
            }
            else if(action.equals(NotificationBarService.SHOW_BOOKMARKS)){
                CustomLogger.log("---------------- BUTTON FOR SHOW DATA WAS PRESSSED!!!");


                //Notification bar buttons start not responding right after
                //this is executed. Note that this problem only occurs if I close the app
                //and press the notification button to execute this code.
                //Otherwise this works just fine.
                Intent intent2;
                intent2 = new Intent(this, BookmarkDisplayActivity.class);
                startActivity(intent2);
            }
        }


        finish();
    }
}

基本上，如果我关闭应用程序并删除启动活动的代码，则两个按钮都按预期工作，但是一旦我启动活动，两个按钮就停止工作了。

好的，我最终解决了我在处理按钮按下方式方面遇到的问题。这是我的解决方案，现在它可以按预期工作。

在NotificationBarService中，这是我处理按钮监听器的方式：

Intent addBookmarkIntent = new Intent(this, NotificationBarButtonListener.class);
            addBookmarkIntent.setAction(ADD_BOOKMARK_ACTION);
            PendingIntent pendingAddBookmarkIntent = PendingIntent.getBroadcast(this, 0, addBookmarkIntent, 0);
            contentView.setOnClickPendingIntent(R.id.notificationBarAddBookmarkFromChromeButton, pendingAddBookmarkIntent);

            Intent showBookmarkIntent = new Intent(this, NotificationBarButtonListener.class);
            showBookmarkIntent.setAction(SHOW_BOOKMARK_ACTION);
            PendingIntent pendingShowBookmarkIntent = PendingIntent.getBroadcast(this, 0, showBookmarkIntent, 0);
            contentView.setOnClickPendingIntent(R.id.notificationBarShowBookmarksButton, pendingShowBookmarkIntent);

然后我收到一个广播事件，并像这样处理它

public static class NotificationBarButtonListener extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {

            final String action = intent.getAction();
            if(action.equals(ADD_BOOKMARK_ACTION)){
                CustomLogger.log("---------------- BUTTON FOR REGISTER BOOKMARK WAS PRESSED!!! ");


            }
            else if(action.equals(SHOW_BOOKMARK_ACTION)){
                CustomLogger.log("---------------- BUTTON FOR SHOW BOOKMARK WAS PRESSSED!!!");

            }

        }
    }

请注意，这要求我将以下行添加到我的清单中。

<receiver android:name=".NotificationBarService$NotificationBarButtonListener"/>
