How to view ArcGIS layer legend in Android?

I have 3 layers (Drainage, Bridge and Slope) in my ArcGIS Feature Server. My Android App view each layer on ArcGISmap, and set layer visibility based on checkbox tick. I am using ArcGIS Runtime SDK for Android (version 100.1).

My question is, is it possible to view the layers’ legend from feature server into my Layers dialog? Means to replace the 3 cute icons.

Android App (Layers dialog in the middle)

Feature Server (layers’ legend on left)

Thank you in advance!
