Exception when setting selector for ListView

Question

I'm trying to set a ListView selector like this:

fileList.setSelector(android.R.layout.simple_list_item_checked);

And I get:

Any idea on why this is happening?

Based on [this](http://stackoverflow.com/questions/2204994/how-do-you-activate-checkmarks-in-list-activity), it looks like simple_list_item_checked is supposed to be passed to the list adapter when it's created, not set directly on the ListView, and based on [this](http://stackoverflow.com/questions/11762235/android-listview-setselector-issue), it looks like ListView.setSelector is expecting a drawable, not a layout. Can you try setting simple_list_item_checked on your adapter, or is there some reason that won't work in your case? — Andy, Oct 02 '12 at 17:48

You're are trying to set as a selector a layout resource from the SDK(that layout file in particular is a simple CheckedTextView element) which obviously will not work as it expects a drawable resource. You most likely want a drawable:

android.R.drawable.something

(for example: android.R.drawable.list_selector_background , the default selector)

@m0skit0 The `android.R.drawable.list_selector` doesn't work? You may want to try the `drawSelectorOnTop` attribute on the `ListView` and see if that works. – user Oct 03 '12 at 07:54
Nope, no go. But if I use `android.R.drawable.screen_background_light_transparent` it does work... but the selector only appears if I scroll the `ListView`. Btw the `ListView` is on a `PopupWindow`. – m0skit0 Oct 03 '12 at 08:11
@m0skit0 The selector from my answer should have worked as it's the default one, I think it has something to do with the `PopupWindow` which has a special focus status(which is used in that selector drawable). I don't know how you created the `PopupWindow` but try to use the last constructor the one which allows the popup to be focusable. – user Oct 03 '12 at 08:28
Yes, I'm pretty sure it has to do with `PopupWindow`. I already set the `PopupWindow` to be focusable by doing `window.setFocusable(true);` – m0skit0 Oct 03 '12 at 08:31

Ok got it to work: in fact I had to remove the focusable state. Thank you for your help! – m0skit0 Oct 03 '12 at 08:38
