android - 即使提供了通知 ID，也不会在单击操作按钮时删除通知

Question

我发送的通知有 2 个操作按钮，即“接受”和“拒绝”。

我正在关注这个 Github repo .

当用户点击“接受”时，会检查某些条件并相应地执行逻辑。

UPDATE 2.0 - 问题是在单击“接受”按钮后，操作成功进行但通知并未从状态栏中消失，因为此处生成的 ID:m = (new Random()).nextInt(10000); 与这里不同:actionIntent.putExtra("id", NotificationARBroadcastReceiver.m); 每一次!

通知代码如下:

Intent notificationIntent = new Intent(getBaseContext(), NotificationARBroadcastReceiver.class);
notificationIntent.putExtra(NotificationARBroadcastReceiver.NOTIFICATION, getNotificationNewRequestService());
PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), m, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, 0, pendingIntent);

这是 getNotificationNewRequestService():

private Notification getNotificationNewRequestService() {

        mBuilder =
                new NotificationCompat.Builder(getBaseContext())
                        .setSmallIcon(R.mipmap.app_icon_1)
                        .setContentTitle("Title")
                        .setContentText("text...");

        Intent resultIntent = new Intent(getBaseContext(), Profile.class);

        PendingIntent resultPendingIntent =
                PendingIntent.getActivity(
                        getBaseContext(),
                        0,
                        resultIntent,
                        PendingIntent.FLAG_UPDATE_CURRENT
                );

        // for action button
        Intent actionIntent = new Intent(getBaseContext(), MyBroadcastSender.class);
        actionIntent.putExtra("id", NotificationARBroadcastReceiver.m);
        PendingIntent actionPendingIntent = PendingIntent
                .getBroadcast(getBaseContext(),
                        0, actionIntent, PendingIntent.FLAG_UPDATE_CURRENT);

        mBuilder.setAutoCancel(true);
        mBuilder.setContentIntent(resultPendingIntent);
        mBuilder.addAction(R.drawable.ic_accepted_request_black_24dp, "Accept", actionPendingIntent);
        mBuilder.addAction(R.drawable.ic_close_black_24dp, "Reject", null);

        return mBuilder.build();
    }

这是 NotificationARBroadcastReceiver.java 文件:

public class NotificationARBroadcastReceiver extends BroadcastReceiver {

    public static String NOTIFICATION = "notification";
    public static NotificationManager mNotifyMgr;
    public static int m;

    @Override
    public void onReceive(Context context, Intent intent) {

        m = (new Random()).nextInt(10000);
        Log.d("mMain", String.valueOf(m));

        mNotifyMgr =
                (NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);

        Notification notification = intent.getParcelableExtra(NOTIFICATION);
        notification.defaults |= Notification.DEFAULT_SOUND;
        notification.defaults |= Notification.DEFAULT_VIBRATE;
        mNotifyMgr.notify(m, notification);

    }
}

这是 MyBroadcastSender.java 文件:

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

        Toast.makeText(context, "Broadcast Received by MyBroadcastSender.", Toast.LENGTH_SHORT).show();

        int id = intent.getIntExtra("id", 1);

        // send back to your class
        Intent newIntent = new Intent();
        newIntent.setAction(context.getString(R.string.broadcast_id));
        newIntent.putExtra("id1", id);
        context.sendBroadcast(newIntent);
        context.sendBroadcast(new Intent(Intent.ACTION_CLOSE_SYSTEM_DIALOGS));
        Toast.makeText(context, "Broadcast sent back.", Toast.LENGTH_SHORT).show();

    }
}

这是 MyBroadcastReceiver.java 文件:

// BroadcastReceiver
    public class MyBroadcastReceiver extends BroadcastReceiver {

        public MyBroadcastReceiver(){
            super();
        }

        @Override public void onReceive(Context context, Intent intent) {

            int id2 = intent.getIntExtra("id1", 1);

            if (intent.getAction() != null && intent.getAction().equals(getString(R.string.broadcast_id))) {

                NotificationARBroadcastReceiver.mNotifyMgr.cancel(id2);

                Intent intent1 = new Intent(MyService.this, MainActivity.class);
                intent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(intent1);

                Toast.makeText(context, "Broadcast received by MyBroadcastReceiver. Now, you can perform actions.",
                        Toast.LENGTH_SHORT).show();

            } else {
                Toast.makeText(context, "Intent is null.", Toast.LENGTH_SHORT).show();
            }
        }
    }

在 getNotificationNewRequestService() 中，我将通知 id 作为附加信息放在 “id” 中，然后在 MyBroadcastSender.java 中，我我得到这个额外的作为 int id = intent.getIntExtra("id", 1); 然后再次作为 newIntent.putExtra("id1", id);然后最终将它作为 int id2 = intent.getIntExtra("id1", 1); 在 MyBroadcastReceiver.java 中获取，并尝试使用它作为 删除通知NotificationARBroadcastReceiver.mNotifyMgr.cancel(id2);.

抱歉代码太多，我必须全部上传，因为它们都是必需的。

我想要的是知道如何将相同的通知 id 从 NotificationARBroadcastReceiver.java(这是一个单独的 java 文件)传送到 MyBroadcastReceiver(这是 MyService.java 中的内部类)？

更新 1.0- 这是我打印出 m、mMain、id 值时发生的情况, id1:

D/m: 0
D/mMain: 9994
D/id: 0
D/id1: 0

假设 getNotificationService() == getNotificationNewRequestService() 看起来在构建和显示通知之前未调用 NotificationARBroadcastReceiver。

您最好在创建通知的地方生成通知 ID，然后将它添加到 Intent 中，您也不需要这样做。

因此从 NotificationARBroadcastReceiver.recieve() 调用 getNotificationNewRequestService() 并确保通知 ID 匹配。
