React native Clojure上的React native-通过id获取ScrollView并滚动到ScrollView中的视图

我有一张标有标记的地图。在地图下方的滚动视图中，我还有一个视图列表（包含标记项目的详细信息）

当我点击地图中的一个标记时，我需要向下滚动到ScrollView中的一个特定视图

这是我的密码

(defn render-link [ctx art]
  (let [{:keys [dimensions]} (get-dimensions)
        route (current-route> ctx)

       [(ui/component ctx :sidebar)]])))

在按下标记时，我需要向下滚动id为“艺术列表视图”的ScrollView

有人能帮忙吗？

我可以通过使用动画滚动视图和以下代码来解决此问题：

[marker {:key (:id art)
                                :coordinate location
                                :on-press (fn []
                                  (when-let [s @scroll-atom]
                                   (navigate-replace! (assoc route :active-id (:id art)))
                                   (ocall s "_component.scrollTo" #js {:x 0 :y (* index 60) :animated false})))}]

列表视图：

[animated-scroll-view {:id "art-list-view"
                                :ref #(reset! scroll-atom %)}
         (doall (map (fn [art]
                       (render-link ctx art)) nearby))]]

你能分享更多的代码吗？什么是

获取维度

ui/component

？什么是

导航替换和
导航开始？可以通过向下滚动至特定点，也可以通过完全向下滚动。
