NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    Notification notification;

        notification = new Notification(R.drawable.messageicon,"You have a new message",System.currentTimeMillis());
        notification.flags |= Notification.FLAG_AUTO_CANCEL;

        RemoteViews view = new RemoteViews(getPackageName(),R.layout.notification);
        view.setImageViewResource(R.id.image,R.drawable.ic_launcher);
        view.setTextViewText(R.id.title,"New Message");
        view.setTextViewText(R.id.text,message);
        notification.contentView = view;
        Intent intent = new Intent();
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
        PendingIntent activity = PendingIntent.getActivity(this,intent,PendingIntent.FLAG_CANCEL_CURRENT);
        notification.contentIntent = activity;
        notificationManager.notify(0,notification);

我想在状态栏上添加一个按钮,单击该按钮时,应显示一个弹出窗口.
任何帮助将受到高度赞赏.
