How to implement a graphic element in android?

Question

Android

Tell me, is such an arrow corner at the bottom of a translucent black layer made using a picture or drawn using Canvas?

Answer 1

canvas

Answer 2

It's easier to do this with an image: use 9.path as the background for the entire container, or make a composite layout.
This arrow casts a shadow and if you draw with pens, you will have to tinker with the canvas.
