I received many positive responses about it from you all, and it seems I really helped a lot of people to get to know this feature well. We should talk about rv_item_list.On my last post on the subject, Write your own Android Authenticator, we embarked on a journey to the unfamiliar part of authentication on Android.
In the constructor you assign an instance of your adapter to this property (note you don’t need to use new in Kotlin) and assign two things to rv_item_list - a LayoutManager (which is used for positioning), and an Adapter (which we’ve just created). So here you’ve defined the adapter as a lateinit variable - lateinit is telling Kotlin that you want to initialize this at some stage after creation, not the default in Kotlin classes - normally you have to initialize things immediately. For example, often you’ll see curly brackets used as function parameters:īuildscript It resembles other languages you may have seen but some things look off, often because it is so concise!ĭon’t panic - because it is so extensible there are many ways to write the same code, and many shortcuts that aren’t available in other languages. Here is the complete code if you rather go straight to the end.īefore we start, let’s talk a bit about Kotlin. If you don’t have any Android experience you should be able to follow along but you might have to Google a few things here and there. I’m going to assume you have some Java experience and have at least played around with creating an Android app. Spring Boot is a great way to create a robust REST API with a minimal amount of code. In this tutorial, you’ll use Spring Boot for the API that powers your Android (+ Kotlin) mobile app. The best way to start is by creating a complete app yourself, which you’ll do in this tutorial. Kotlin was recently given official Android support status by Google, but it remains difficult to understand for many developers.
