Android通知栏，应始终可见。通知栏有2个按钮，其中第一个是抓一些数据存储和第二个开放活动，将显示所有的数据。我遇到了一个问题，当我关闭应用程序，然后按通知按钮开始活动，活动开始后，我通知按钮停止响应。需要注意的是按键做工精细前点所在的第二按钮点击开始活动。

这里是一个模板代码为我的通知服务和通知栏按钮处理程序

服务处理的通知栏

 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);

        }
    }

类处理按钮按下通知栏

  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();
    }
}

最后，我终于解决了这个问题，我在改变，我处理按键的方式。这是我现在的工作。

在NotificationBarService，可以这样处理按钮

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);

然后我收到广播甚至和处理这样的

  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!!!");

            }

        }
    }
