Today I spent several hours experimenting with custom ActionMode views. First, I made something with menu items triggering custom dialogs. It was very rough so I decided to go with a custom layout. I have noticed ActionMode.setCustomView(View) <http://developer.android.com/reference/android/support/v7/view/ActionMode.html#setCustomView(android.view.View)>. The function itself is documented as it should but I've failed in finding a sample or example of how to use this functionality.
The main problem is I don't know how to inflate the view so it is valid to use. Using the debugger I've seen there are inflaters and views in SupportActionModeWrapper but it doesn't seem to expose anything like a ViewGroup I can use as a parent to inflate layout. I've tried various methods and they mostly result in one of those two behaviors: 1. the action mode bar is empty (only ← is shown). This is the case if I inflate with null root. 2. I get a crash due to my view already having a parent. Trace suggests to call .removeView on the root I used to inflate but apparently that needs to be done recursively as doing that for the view I inflated didn't do a thing. How is setCustomView supposed to be used? I was thinking about creating a menu with a <group> and try to put stuff there but it doesn't look like MenuItem supports this kind of use. BTW, what is a proper root? For the lack of a better candidate, I used the activity content layout I've marked using an ID but I know this is not right. I would expect the ActionMode to contain some kind of layout - and I've seen something similar by walking in it using the debugger but I don't see any public interface to access the root. I've read the "menus" API guide <http://developer.android.com/guide/topics/ui/menus.html#CAB> over and over and looked all across the documentation. Shouldn't there be a getSupportActionModeBar() kind of thing? I've found several information on the net about .setCustomView but they seem to be related to (I assume to be) obsolete action bar versions. I don't recall finding anything useful. I would eventually consider other UI designs but of course this would be my first choice. Pretty much everything would be appreciated at this point, including simple search keywords!
