Exchange rates sample project

Description

The sample loads an initial list of exchange rates then auto refreshes the list every second. A rate can be selected as primary base rate and becomes first in the list.

Features

  • Model-View-Intent architecture
  • Data layer using repository pattern with a single remote source
  • Presentation layer contains a fragment (View) and a ViewModel
  • Reactive UI using RxJava2

Further optimizations

drawing

Scrolling fast through the list causes UI jitters. When profiling it seems to be a problem from updating a lot of TextViews at the same time. Performance can be improved by creating a custom view for the list item.
