Keyboard blinks when AutoCompleteTextView dropdown is shown

Question

I'm using AutoCompleteTextView inside DialogFragment. When it shows a dropdown list, keyboard hides and shows again very fast, it looks like a blink.

As possible solution, I found that it happens because of

AutoCompleteTextView {

    showDropDown(){
       mPopup.setInputMethodMode(ListPopupWindow.INPUT_METHOD_NEEDED);
    }
}

So overriding showDropDown() in this way removes blink

showDropDown(){
    super.showDropDown()
    mPopup.setInputMethodMode(ListPopupWindow.INPUT_METHOD_FROM_FOCUSABLE)
    mPopup.show()
}

But it shows dropdown above keyboard and blocks user input. Maybe someone knows better solution?

I'm running into the same problem. Seems to be new to android Q. I'll keep looking, but I got about as far as you did (at which point I came across your question). — etrado, Dec 09 '19 at 17:58
@etrado I have not found any solution. So I replaced `AutoCompleteTextView` with `TextInputEditText` and a `ListView` (with filterable `ArrayAdapter`) inside `ConstraintLayout` looks ok. But you need to handle `ListView` visibility — Ufkoku, Dec 10 '19 at 10:16

You're not going to believe this, but I am pretty sure the December 5 patch to android Q fixed this problem. I got the update this morning, and I was hoping since it was a relatively new issue that they might have addressed it. Turns out they did! I get no more flashing keyboard when using the AutocompleteTextView.
