Android SearchView.OnQueryTextListener OnQueryTextSubmit not fired on empty query string

Question

I am using Android 4.1.2. I have a SearchView widget on an ActionBar. Documentation on SearchView.OnQueryTextListener

It's an old thread but I've found another solution (Kotlin code, but works in Java as well):

override fun onQueryTextChange(newText: String?): Boolean {
            if(newText == null || newText.isEmpty())
                searchView.setQuery("\u00A0", false)
            return true
        }

\u00A0 is a character that looks like space, but code-wise it is not. In other words SearchView is not empty. Empty string or " " would not work, because base SearchView uses trim, plus user may want to search text ending or beginning with space. But as far as I know users cannot enter \u00A0 character.

Then all you need to do is override getQuery to return super.getQuery.replace("\u00A0", "") in your custom SearchView
