Android Question Check if a view has already been added to an Activity

[moster67]

I add AdMob's BannerAd view to an activity using:

Activity.AddView(BannerAd, 0dip, 100%y - AdMobHeight, 100%x, AdMobHeight)

Later somewhere in my code, I remove it by using:

BannerAd.RemoveView

At a certain point, , I want to check its status i.e. if it is loaded (added) or not.

How can I do that?

One way is to check if the view has a parent.

One way is to check if the view has a parent.

Can you show a code snippet which does that?

 

[Cableguy]

I never did, but there are already snippets using reflection about getting views properties that are not accessible through the views directly...

Check this thread:

Another method: You can add views to a list, too. So if you add a view, add it to the list, too. When you remove it, remove it from the list. Check the list, to check if the view is available.

Hi,
I don't know about AdMob's BannerAd, but if it's a view it should sport a Tag property. So set a special value for it before adding and then check for that value cycling on your activity's views when you need to know if it's part of the group.

You can check:

If BannerAd.Parent <> Null Then
 'it was added
End If

Thank you all for your input.
At the end I went with Erel's suggestion.
