Update ListView on UI on receiving Broadcast intent

Question

I have a list of items on the UI. When the app catches an intent with a BroadCastReceiver , I need to update a specific item in the list (hide an ImageView on the item row). The list uses a custom adapter obviously. How can I do that?

I tried access the fragment where is the ListView using the Application object called from the receiver, but Android gave me this error:

"Only the original thread that created a view hierarchy can touch its views"

Sorry if I'm a bit generic, but I don't know which part of the code provide, actually.

Answer 1

I'm guessing that you're trying to edit the list from another thread that received this Broadcast. if indeed this is the case there is a simple solution - the Activity class supplies a method called - runOnUiThread. You can see an example on this post : Android “Only the original thread that created a view hierarchy can touch its views.

Good Luck!
