copied!<p>I'll post an example with a way I did it in one of the apps I created. </p> <p>When calling the alarm you need to send an extra id like this: Tmp is an object which has a unique ID. </p> <pre><code>Intent intent = new Intent(DisplayActivity.this,AlarmReciever.class); intent.setData(Uri.parse("timer:"+tmp.getId())); PendingIntent pendingIntent = PendingIntent.getBroadcast(DisplayActivity.this,1, intent, 0); AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE); am.set(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(),pendingIntent); </code></pre> <p>and then you retrieve the id with this line: </p> <pre><code>Long.parseLong(intent.getData().getSchemeSpecificPart()) </code></pre> <p>When cancelling just create the same pending intent with the ID and call alarmmanager.cancel()</p> <p>Edit:</p> <p>To cancel the specific alarm on the item the user clicked on (here is where tmp.getId comes in handy) I just used this code, I think you need to create the same pendingIntent to be able to cancel the specific alarm. </p> <pre><code> Intent intent = new Intent(DisplayActivity.this,AlarmReciever.class); intent.setData(Uri.parse("timer:"+tmp.getId())); PendingIntent pendingIntent = PendingIntent.getBroadcast(DisplayActivity.this,1, intent, 0); AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE); am.cancel(pendingIntent); </code></pre> <p>AlarmReciever is my BroadcastReceiver. DisplayActivity is the activity itself. </p> <p>It's in AlarmReciever I have the following code: </p> <pre><code>Long.parseLong(intent.getData().getSchemeSpecificPart()) </code></pre>
