Android: How to create a custom dropdown dialog?

Question

I need to create a dialog which drops down from a clicked position on the screen.

I have considered using a floating ContextMenu, but I need to customize the contents of the dropdown to display my own views.

I have also considered using a custom DialogFragment but this is not subtle enough and interrupts the flow.

How can I create something in between?

A perfect example would be the dropdown dialog used by Duolingo:

I have also considered just adding a framelayout to the point where the user clicks but I'm not sure how to recreate the dept of a ContextMenu or how to create a decent animation when the dialog is fading in and out.

I dont want to display a list of options within the dialog, I want to display a custom layout with a number of textviews and buttons.

You need to use [Popup Window](https://developer.android.com/reference/android/widget/PopupWindow) — Rahul Khurana, Jul 04 '19 at 10:51
