Listview row color not changed from asynctask

Question

I am trying to update color of listview from async task postexecute method.

I am doing ((View) lstChoices.getAdapter().getView(0,null, lstChoices)).setBackgroundColor(Color.RED);

But this is not doing anything, but I tried the same in getView method of my custom adapter then it worked, row.setBackgroundColor(Color.RED); Any ideas what I am doing wrong?

Thanks

Answer 1

You should not change this that way. All what is related to the row should be handled in adapter. It means that if you changed anything that could influence background color, then all you should do is notifyDatsetChanged() which would trigger list redraw. And b/g color should be then changed by adapter.

Answer 2

A very clearly presented approach to Listview Item Background color changing based on the item's State is at Programmatically select item ListView in Android

Since you are looking for 'postexecute' perhaps changing the Item's State and using that approach can help you get what you are after.
