问题 I'm wondering how can I do a dropdown button / menu like the ones we can see in the designs specs from Google and in the image bellow, so the list expands bellow right bellow the button. Do I need to set a custom layout for it instead of the R.layout.support_simple_spinner_dropdown_item ? 回答1: Technically it's just a Spinner with custom views and styles. I tried to make one that looks similar to the one you posted, using AppCompat, working with custom drawables and with the view's elevation

I would instead like to intercept the event and set the focus to another control manually. However, I didn't find the event that I need to intercept. How could I
