在不打开应用程序的情况下通过操作按钮关闭正在进行的 Android 通知 [英] Dismiss Ongoing Android Notification Via Action Button Without Opening App

问题描述

我有一个应用程序，它有一个持续的通知来帮助记忆.我希望能够使用操作按钮之一关闭此通知，但我不想在点击按钮时打开应用程序.我更喜欢使用内置的通知操作按钮，而不是创建 RemoteViews 对象来填充通知.我看到一篇帖子提到在我的应用程序中收到的这个按钮上使用 BroadcastReceiver，虽然他的教程非常无用，但听起来这是朝着正确的方向前进.

I have an app that has an ongoing notification to help with memorization. I want to be able to dismiss this notification with one of the action button, but I don't want to open the app when the button is hit. I would prefer to use the built-in notification action buttons and not create a RemoteViews object to populate the notification. I saw one post mention using a BroadcastReceiver on this button which is received in my app, and though his tutorial was quite unhelpful, it sounds like this is headed in the right direction.

Intent resultIntent = new Intent(getBaseContext(), Dashboard.class);
    TaskStackBuilder stackBuilder = TaskStackBuilder.create(getBaseContext());
        stackBuilder.addParentStack(Dashboard.class);
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent =
                stackBuilder.getPendingIntent(
                    0,
                    PendingIntent.FLAG_UPDATE_CURRENT
                );
    Intent cancel = new Intent(getBaseContext(), CancelNotification.class);
        stackBuilder.addParentStack(Dashboard.class);
        stackBuilder.addNextIntent(cancel);
        PendingIntent pendingCancel =
                stackBuilder.getPendingIntent(
                    0,
                    PendingIntent.FLAG_UPDATE_CURRENT
                );

    NotificationCompat.Builder mb = new NotificationCompat.Builder(getBaseContext());
        mb.setSmallIcon(R.drawable.cross_icon);
        mb.setContentTitle(ref);
        mb.setContentText(ver);
        mb.setPriority(NotificationCompat.PRIORITY_LOW);
        mb.setOngoing(true);
        mb.setStyle(new NotificationCompat.BigTextStyle().bigText(ver));
        mb.setContentIntent(resultPendingIntent);
        mb.addAction(R.drawable.ic_cancel_dark, "Dismiss", pendingCancel);

    manager.notify(1, mb.build());  

推荐答案

从这个开始:

int final NOTIFICATION_ID = 1;

//Create an Intent for the BroadcastReceiver
Intent buttonIntent = new Intent(context, ButtonReceiver.class);
buttonIntent.putExtra("notificationId",NOTIFICATION_ID);

//Create the PendingIntent
PendingIntent btPendingIntent = PendingIntent.getBroadcast(context, 0, buttonIntent,0);

//Pass this PendingIntent to addAction method of Intent Builder
NotificationCompat.Builder mb = new NotificationCompat.Builder(getBaseContext());
.....
.....
.....
mb.addAction(R.drawable.ic_Action, "My Action", btPendingIntent);
manager.notify(NOTIFICATION_ID, mb.build());  

创建广播接收器:

public class ButtonReceiver extends BroadcastReceiver {

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

        int notificationId = intent.getIntExtra("notificationId", 0);

        // Do what you want were.
        ..............
        ..............

        // if you want cancel notification
        NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        manager.cancel(notificationId);
    }
}  

如果您不想在用户单击通知时显示任何活动，请以这种方式定义在 setContentIntent 中传递的意图:

If you don´t want show any activity when user click on notification, define the intent passed in setContentIntent in this way:

PendingIntent resultPendingIntent = PendingIntent.getActivity(context,  0, new Intent(), 0);
......
......
mb.setContentIntent(resultPendingIntent); 

要在单击时关闭通知托盘，请在构建通知时使用 true 调用 setAutoCancel():mb.setAutoCancel(true);

To close notification tray when clicked, call setAutoCancel() with true when building the notification: mb.setAutoCancel(true);
