![]() ![]() Before creating your first observable, indulge yourself with a bit of theory first. ![]() Of course, it’s not going to stay like that forever, you’ll soon begin adding reactive functionality to the app. You should see a gloriously empty search screen: It accepts a text search query and returns a list of matching cheeses.īuild and run the project on your Android device or emulator. It has a search function which you call when you want to search for cheeses. cheeseSearchEngine: A field which is an instance of CheeseSearchEngine.showResult(result: List ): A function to display a list of cheeses.hideProgress(): … and a function to hide it.showProgress(): A function to show a progress bar….The CheeseActivity class extends BaseSearchActivity take some time to explore BaseSearchActivity and check out the following features ready for your use: You’ll be working in both CheeseActivity.kt and CheeseAdapter.kt. I hope you are not lactose intolerant - because you’re going to build a cheese-finding app as you learn how to use RxJava! :] Getting Startedĭownload cheesefinder-starter and open it in Android Studio 3.3.2 or above. Use RxJava’s Maybe to add a favorite feature to the app.Turn all your observables into Flowable constructs.Combine several observables into one stream.Leverage Rx threading in code execution.Turn asynchronous events like button taps and text field context changes into observable constructs.Grasp the concepts of Reactive Programming.In this RxAndroid tutorial for reactive programming, you will learn how to do the following: To get up to speed, check out our Android Development Tutorials first and return to this tutorial when you’re ready. Note: This tutorial requires good knowledge of Android and Kotlin. ![]()
