如何在单击通知时打开应用程序？

Question

I have implemented media notification and lock screen notification in my music player. While clicking lock screen notification, how to ask the password to the user and how to open the application.

As well as for media notification while clicking I have opened the application. But how to close the notification bar or how to hide the whole notification bar

and how to show the suggestion of my application in "open with " while clicking the music file in any file directory.

Answer 1

What do you mean by ask for password? just open an activity that asks for password.

As for open an activity use Nirali solution in: Open application after clicking on Notification

 NotificationManager notificationManager = (NotificationManager) context
        .getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);

Intent notificationIntent = new Intent(context, HomeActivity.class);

notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
        | Intent.FLAG_ACTIVITY_SINGLE_TOP);

PendingIntent intent = PendingIntent.getActivity(context, 0,
        notificationIntent, 0);

notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, notification);

For "open with" you should define intent-filter in your manifest. Look at this register as music player and https://developer.android.com/guide/components/intents-filters.html
