How do I create an Android Spinner as a popup?

Question

I want to bring up a spinner dialog when the user taps a menu item to allow the user to select an item.

Do I need a separate dialog for this or can I use Spinner dir

Answer 1

You can use a spinner and set the spinnerMode to dialog, and set the layout_width and layout_height to 0, so that the main view does not show, only the dialog (dropdown view). Call performClick in the button click listener.

    mButtonAdd.setOnClickListener(view -> {
        spinnerAddToList.performClick();
    });

Layout:

The advantage of this is you can customize your spinner any way you want.
