I'm trying to detect when my notification gets cleared. My question dire开发者_如何学编程ctly 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?
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>
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.
You should use getBroadcast methode instead getService and should register receiver for specific Action.
An explicit receiver is not required. deleteIntent will be called automatically while pressing the clear button.
