How to use Notification.deleteIntent

问题:

I'm trying to detect when my notification gets cleared. My question directly refers to this answer which outlines what I'm suppose to do. This is how I'm implementing the actions:

// usual Notification initialization here
notification.deleteIntent = PendingIntent.getService(context, 0, new Intent(context, CleanUpIntent.class), 0);
notificationManager.notify(123, notification)

This is the CleanUpIntent class:

class CleanUpIntent extends IntentService {
    public CleanUpIntent() {
        super("CleanUpIntent");
    }

    @Override
    protected void onHandleIntent(Intent arg0) {
        // clean up code
    }
}

Afterwards, I simply launch the notification like I normally would but when I go to test it out (pressing "Clear All Notifications") nothing happens. I inserted a line of code that out print something to LogCat when the IntentService gets started, but nothing ever ran. Is this how I'm suppose to use Notification.deleteIntent?

回答1:

What you need to do is register a BroadcastReceiver (probably in your AndroidManifest.xml or alternatively using registerReceiver in a Service) and then set deleteIntent to be an Intent that will be caught by that receiver.

sample code which will be called whenever user clears the notification, hope it will help you .

 ....
 notificationBuilder.setDeleteIntent(getDeleteIntent());
 ....


protected PendingIntent getDeleteIntent()
 {
    Intent intent = new Intent(mContext, NotificationBroadcastReceiver.class);
    intent.setAction("notification_cancelled");
    return PendingIntent.getBroadcast(mContext, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
}

NotificationBroadcastReceiver.java

@Override
    public void onReceive(Context context, Intent intent)
    {
        String action = intent.getAction();
        if(action.equals("notification_cancelled"))
        {
            // your code
        }
    }

AndroidManifiest.xml

 <receiver android:name=".NotificationBroadcastReceiver">
                <intent-filter>
                    <action android:name="notification_cancelled"/>
                </intent-filter>
            </receiver>

回答3:

You should use getBroadcast methode instead getService and should register receiver for specific Action.

回答4:

An explicit receiver is not required. deleteIntent will be called automatically while pressing the clear button.
