In advance of a new series of posts which start next week, I ported the code from a previous series of articles to Kotlin. I opted to port the code manually rather than rely on any automated conversions and there are a couple of things worthy of explanation hence this article.
Currency Curiosities
Formatting currency values can be tricky because to do it correctly requires knowledge of each individual currency and how it should be rendered. Fortunately the java.text package contains some classes which have that local knowledge which means that us developers do not need it, except in really rare circumstances. However, there are some subtleties to…
RadialGradient – Gradients
In a recent series of posts for the MidiPad app, there was a discussion regarding the use of a RadialGradiant to render each PadView and, for aesthetic reasons, this was done using a software layer rather than a hardware layer. In this concluding article we’ll explore a way of adapting things to use a hardware…
RadialGradient – Layers
In a recent series of posts for the MidiPad app, there was a discussion regarding the use of a RadialGradiant to render each PadView and, for aesthetic reasons, this was done using a software layer rather than a hardware layer. In this short series we’ll first take a look at what the differences are, and…
MidiPad – Midi Events
Musical Instrument Digital Interface (MIDI) has been around since the early 1980’s and the basic specification has changed little since. It is a standard by which electronic musical instruments and other devices can communicate with each other. In Marshmallow (V6.0 – API 23) Android actually got some good MIDI support, and in this series of…

Kotlin Testability – Part 2
The more observant regular readers of Styling Android will be aware that recently all of the sample code has switched from Java to Kotlin. There are many aspects of Kotlin which make our lives as developers much easier and recently I have been exploring how to make Kotlin classes easier to test. In this short…
