Replace marker with Imageview

[NimaaZx]

Hey. thanks to developers. I don't think so the things I want to mention , it is a bug!
I wanted to use this cool library to create timeline view like this.

there is no problem if I just put SVG drawable inside timelineview. even I could change size of drawable. everything worked fine . the problem that I found out is that I am not able using ImageView instead of marker. I read an old issue that you mention we can't do it.
my Image contains a curve Square and inside it there is a SVG. sometime I need to set the background of Square to yellow and sometimes white color. middle SVG icon color should be changed. I can't use imageview .ok .
I grouped two layer (icon and square) together is one SVG but changing background color did not work good as I excepted . it ruined front icon and nothing visible.

I think I can't implement imageview instead of marker. I use static number of steps (it is 3) . so I have to create 3 imageviews manually and connect them together. or create a custom recyclerview (hard and need more time). I don't know neither about each method performance.
unfortunately I have to put your library aside and not use it .

Do you have any suggestion or tips or am I wrong?
