I want to create a dialog with a pointer which points to where the user has tapped. Something like what has been done in the native music app. I searched a lot, but don’t know what exactly it is called, so i am attaching the screenshot of what I want to achieve.

Creating a dialog is easy, but how do I make it “point” dynamically?
