How do I know that the notification displayed in the notification bar has been clicked?

It seems that no one has such a demand? Let me talk about my needs!

The company develops push ads, and then I need to know if the user has clicked the notification to count the click rate!

Of course, the general push is to start your own activity, so you can listen when your activity starts!

But I designed it like this:

1. If the application has been installed, intent opens the application.

2. If a webpage is pushed, intent calls the system browser to browse the webpage.

3. If the push application is not installed, intent starts the installation.

This is not a target activity at all. What should we do?

First, let's look at how to display notifications and check the Code:

Intent intent = new intent (mainactivity. this, testreceiver. class); intent intent2 = new intent (intent. action_view, Uri. parse ("http://wap.baidu.com"); intent2.addflags (intent. flag_activity_new_task); intent. putextra ("intent", intent2); Notification = new notification (R. drawable. ic_launcher, null, system. currenttimemillis (); pendingintent contentintent = pendingintent. getbroadcast (this, 0, Intent, pendingintent. flag_update_current); notification. setlatesteventinfo (this, "good morning! "," Today is a clear day! ", Contentintent); notification. Flags | = notification. flag_auto_cancel; icationicationmanager mnm = (icationicationmanager) getsystemservice (context. icationication_service); mnm. Notify (1001, notification );

Notifycation requires a pendingintent

1. getactivity gets the pendingintent that starts an activity.

2. getservice starts the service

3. getbroadcast starts broadcastreceiver

Take getbroadcast as an example. The third parameter is intent, which is the intent of the broadcastreceiver to be started. However, intent itself can use putexter () to store an intent object.

: You only need to put the true intent into the intent that starts broadcastreceiver, and then extract the intent from the onreceiver of boradcastreceiver to start the real activity, of course, if what you really want to start is not an activity, you can put a flag to determine which components to start!

View code:

public void onReceive(Context context, Intent intent) {System.out.println("onReceive");Toast.makeText(context, "onReceive", Toast.LENGTH_SHORT).show();Intent intent2 = (Intent)intent.getParcelableExtra("intent");//intent2.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);context.startActivity(intent2);}

Note:

1. An error is reported when the activity is directly started in the oncycler context. You need to add the intent. flag_activity_new_task flag to the intent!
