检索通知意图以将用户重定向到应用程序的特定活动

问题描述

我正在制作一个使用Android中的NotificationListenerService收集推送通知的应用程序。 检索通知内容，例如应用程序名称，应用程序内容，程序包名称，通知注册时间等，效果很好。 但是，当尝试检索通知时，如果单击该意图，该意图会将用户重定向到应用程序的特定活动，则该意图不起作用。它不会得到意图。可能是什么问题？

try {
            //ne.cls_intent = getIntent(sbn.getNotification().contentIntent).toString();
                ne.cls_intent =getIntent(notification.contentIntent).resolveActivity(pm).getClassName();
    } catch (IllegalStateException e) {
                ne.cls_intent = "No Intent";
    }

解决方法

尝试一下，@ Hyeon

Intent intent = new Intent(getApplicationContext(),Your_Desired_Activity.class);
            intent.putExtra("Key",value); //for sending data to your specific activity if needed.
            
PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(),(int) (Math.random() * 100),intent,PendingIntent.FLAG_UPDATE_CURRENT);

           NotificationManager mNotificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);

            String NOTIFICATION_CHANNEL_ID = "101";

            //TODO - make the title BOLD - change the notification icons
            mBuilder = new NotificationCompat.Builder(getApplicationContext(),NOTIFICATION_CHANNEL_ID);
            mBuilder.setContentTitle(message_push)
                    .setSmallIcon(R.drawable.app_logo)
                    .setContentText(event_title_push)
                    .setAutoCancel(true)
                    .setVibrate(new long[]{100,200,300,400,500,400})
                    .setCategory(NotificationCompat.CATEGORY_MESSAGE)
                    .setPriority(NotificationCompat.PRIORITY_HIGH)
                    .setColor(getColor(R.color.text_color))
                    .setContentIntent(pendingIntent);

            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
                CharSequence name = getString(R.string.app_name);
                int importance = NotificationManager.IMPORTANCE_HIGH;
                NotificationChannel channel = new NotificationChannel(NOTIFICATION_CHANNEL_ID,name,importance);
                channel.setDescription(event_title_push);
                // Register the channel with the system; you can't change the importance
                // or other notification behaviors after this
                mNotificationManager = getSystemService(NotificationManager.class);
                channel.setImportance(importance);
                mBuilder.setChannelId(NOTIFICATION_CHANNEL_ID);
                mNotificationManager.createNotificationChannel(channel);
            }
            assert mNotificationManager != null;

            // Cancel the notification after the particular notification gets selected
            mBuilder.getNotification().flags |= Notification.FLAG_AUTO_CANCEL;
            
            mNotificationManager.notify((int) (Math.random() * 100) /* Request Code */,mBuilder.build());

这是显示带有标题和振动的通知以及重定向到特定活动的全部工作。
