[SOLVED] Android SearchView only briefly displays cursor when I click on search input field, and no keyboard displays. Can't input text

I'm trying to implement a SearchView inside of a layout, not in a menu layout, but when I click on the search input box, the cursor just briefly shows, then disappears, and the keyboard never displays. It seems like its loosing focus possibly? I've been trying to figure this out for a while now with zero luck.

Code is below. Has been edited for clarity.

Thanks for any ideas or suggestions.
