Menggambar tampilan jam

Setelah mengonfigurasi project dan menambahkan class yang mengimplementasikan
layanan tampilan jam, Anda dapat mulai menulis kode untuk melakukan inisialisasi dan menggambar
tampilan jam kustom.
Setiap tampilan jam akan membuat subclass kustom dari perender yang menerapkan
semua yang diperlukan untuk menggambar tampilan jam.
Perender menggabungkan
UserStyle,
informasi detail dari
ComplicationSlotsManager,
waktu saat ini, dan informasi status lainnya untuk
merender tampilan jam, seperti ditunjukkan pada contoh berikut:
class CustomCanvasRenderer(
private val context: Context,
surfaceHolder: SurfaceHolder,
watchState: WatchState,
private val complicationSlotsManager: ComplicationSlotsManager,
currentUserStyleRepository: CurrentUserStyleRepository,
canvasType: Int
) : Renderer.CanvasRenderer(
surfaceHolder = surfaceHolder,
currentUserStyleRepository = currentUserStyleRepository,
watchState = watchState,
canvasType = canvasType,
interactiveDrawModeUpdateDelayMillis = 16L
) {
override fun render(canvas: Canvas, bounds: Rect, zonedDateTime: ZonedDateTime) {
// Draw into the canvas
}
override fun renderHighlightLayer(canvas: Canvas, bounds: Rect, zonedDateTime: ZonedDateTime) {
// Draw into the canvas
}
}
