Question

我发送的通知中有2个操作按钮，即＃34;接受＆＃34;和＆＃34;拒绝＆＃34;。

当用户点击＆＃34;接受＆＃34;时，会检查某些条件并相应地执行逻辑。

更新2.0 - 问题是点击＆＃34;接受＆＃34;按钮，操作成功发生，但通知不会从状态栏中消失，因为此处生成的ID：m = (new Random()).nextInt(10000);与此处不同：actionIntent.putExtra("id", NotificationARBroadcastReceiver.m);每次都有！

这是通知代码：

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);

此处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();
    }

此处有NotificationARBroadcastReceiver.java个文件：

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);

    }
}

此处有MyBroadcastSender.java个文件：

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();

    }
}

以及此处MyBroadcastReceiver.java档案：

// 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"id"中的额外内容添加，然后在MyBroadcastSender.java中，我将此额外内容设为int id = intent.getIntExtra("id", 1);然后再次将其设为newIntent.putExtra("id1", id);，最后将其作为MyBroadcastReceiver.java添加到int id2 = intent.getIntExtra("id1", 1);并尝试使用NotificationARBroadcastReceiver.mNotifyMgr.cancel(id2);删除通知。

对于这么多代码感到抱歉，我必须将它们全部上传，因为它们都是必需的。

我想要的是知道如何将NotificationARBroadcastReceiver.java（这是一个单独的java文件）中的相同通知ID传递给MyBroadcastReceiver（这是一个内部类） MyService.java）？

更新1.0 - 这是我打印出m，mMain，id，id1的值时发生的事情：

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

Answer 1

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

您最好在您创建通知的位置生成通知ID，并将其添加到意图中，您也不需要这样做。

所以从NotificationARBroadcastReceiver.recieve（）调用getNotificationNewRequestService（）并确保通知ID匹配。

Answer 2

修改：

举：

m = (new Random()).nextInt(10000);

之前：

actionIntent.putExtra("id", NotificationARBroadcastReceiver.m); // this will be 'm'

结果：

int m = (new Random()).nextInt(10000);
Intent actionIntent = new Intent(getBaseContext(), MyBroadcastSender.class);
actionIntent.putExtra("id", m);
Log.d(getClass().getSimpleName(), "Notification Id is : " + m);

然后，您可以查看id，id1和id2中的值。不要忘记使用.notify()中的相同ID来呼叫m。

您还可以创建getRandomNotificationId()和getLastGeneratedNotificationId()方法。无论何时生成Id，都将其存储在public static整数变量中，以便您可以在整个班级中访问它。

问题可能是您在初始化之前从m访问NotificationARBroadcastReceiver。所以，肯定是0。并且，您提到了println错误，您使用的是System.out.println()吗？

编辑前：

如新编辑所示，请在启动前尝试关闭通知：

m = (...);

// some code here

mNotifyMgr.cancel(m);
mNotifyMgr.notify(m, notification);

并查看您的问题是否得到解决。

即使在提供通知ID后，也无法通过单击操作按钮删除通知
