Hi I made this using patterns from other people. In this snippet, I am making an rx implementation of opengles renderer.
class OnSubscribeRenderer(private val surfaceView: GLSurfaceView,
private val previewSize: Size) : Observable<SurfaceEvent>() {
// TODO make a github gist and ask to community for insights
override fun subscribeActual(observer: Observer<in SurfaceEvent>) {
val listener = Listener(observer, previewSize)
observer.onSubscribe(listener)
surfaceView.setEGLContextClientVersion(2)

learning rxjava
fun loadFirstPage(): ObservableTransformer<LoadFirstPageAction, MainResult> {
return ObservableTransformer {
actionStream -> actionStream.flatMap { _ -> mainModel.getNews("", "10") // <-- whats wrong with you! took 1 day of my life
.map { data -> MainResult.success(data) }
.onErrorReturn { error -> MainResult.failure(error.message ?: "Unknown error") }
.observeOn(AndroidSchedulers.mainThread())
.startWith { MainResult.loading()} }
}
}
