绘制手表表盘

在配置您的项目并添加实现手表表盘服务的类之后，您可以开始编写代码来初始化和绘制您的自定义手表表盘。

每个手表表盘都会创建一个渲染器的自定义子类，该子类实现绘制手表表盘所需的一切。

渲染器将 UserStyle、来自 ComplicationSlotsManager 的复杂信息、当前时间和其他状态信息组合在一起以渲染手表表盘，如以下示例所示

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
    }
}
