ItemizedOverlay Adding Items and onTap Issue

Postby aspekt9 » Fri Feb 05, 2010 5:35 am

When I add a new item to my ItemizedOverlay the onTap display I have set appears X times, where X is equal to the number of items that I added. So for example, if I add one item and tap it, it the onTap method gets called once, and in the LogCat I get:

Code: Select all
02-04 23:28:56.188: INFO/NotificationService(52): enqueueToast pkg=android.mapit callback=android.app.ITransientNotification$Stub$Proxy@4394c100 duration=0


If I add a second item and click ANY of the other items, the onTap method gets called twice and I get the following in LogCat:

Code: Select all
02-04 23:29:29.408: INFO/NotificationService(52): enqueueToast pkg=android.mapit callback=android.app.ITransientNotification$Stub$Proxy@438b4048 duration=0
02-04 23:29:29.418: INFO/NotificationService(52): enqueueToast pkg=android.mapit callback=android.app.ITransientNotification$Stub$Proxy@43950d20 duration=0


If I add a third item and click ANY of the other items, the onTap method gets called three times and I get the following in LogCat:


Code: Select all
02-04 23:30:32.007: INFO/NotificationService(52): enqueueToast pkg=android.mapit callback=android.app.ITransientNotification$Stub$Proxy@4394fcf8 duration=0
02-04 23:30:32.017: INFO/NotificationService(52): enqueueToast pkg=android.mapit callback=android.app.ITransientNotification$Stub$Proxy@43950408 duration=0
02-04 23:30:32.028: INFO/NotificationService(52): enqueueToast pkg=android.mapit callback=android.app.ITransientNotification$Stub$Proxy@438babe0 duration=0



Any idea why this would occur? I'm running into issues with it affecting other things like removal of items.

boolean to return from onTap()

Postby EsterYtterbrink » Tue Apr 13, 2010 11:54 am

Hi, have you tried to return true from your onTap() ?

http://code.google.com/intl/sv-SE/andro ... index.html

To return false indicates that you want the event that generated it to pass to other overlays.

best regards Ester Ytterbrink
