HarmonyOS 地图的marker怎么支持自定义布局

marker的icon属性支持image.PixelMap和Resource类型的。

可以根据需要绘制好样式，以图片的格式作为marker的icon传进来。比如可以自定义一个builder函数，通过componentSnapshot把builder函数转成pixelmap。详细信息和示例请参考如下地址：componentSnapshot.createFromBuilder

import { map, mapCommon, MapComponent } from '@kit.MapKit';
import { AsyncCallback } from '@kit.BasicServicesKit';
import { image } from '@kit.ImageKit';
import { componentSnapshot } from '@kit.ArkUI';

@Entry
@Component
struct CustomizationMarker {
  private mapOptions?: mapCommon.MapOptions;
  private mapController?: map.MapComponentController;
  private callback?: AsyncCallback<map.MapComponentController>;
  @State imagePixelMap: PixelMap | undefined = undefined;

  addMarker() {
    componentSnapshot.createFromBuilder(() => {
      this.RandomBuilder()
    },
      async (error: Error, pixmap: image.PixelMap) => {
        if (error) {
          console.log("error: " + JSON.stringify(error))
          return;
        }

        // Marker初始化参数
        let markerOptions: mapCommon.MarkerOptions = {
          position: {
            latitude: 31.984410259206815,
            longitude: 118.76625379397866
          },
          rotation: 0,
          visible: true,
          zIndex: 0,
          alpha: 1,
          anchorU: 0.5,
          anchorV: 1,
          clickable: true,
          draggable: true,
          flat: false,
          icon: pixmap
        };
        console.log('testTag', `addMarker`)
        this.mapController?.addMarker(markerOptions);
      })
  }

  aboutToAppear(): void {
    // 地图初始化参数
    this.mapOptions = {
      position: {
        target: {
          latitude: 31.984410259206815,
          longitude: 118.76625379397866
        },
        zoom: 15
      }
    };
    this.callback = async (err, mapController) => {
      if (!err) {
        console.log('testTag', `callback`)
        this.mapController = mapController;
        this.addMarker()
      }
    };
  }

  @Builder
  RandomBuilder() {
    Row() {
      Image($r('app.media.marker')).width(18).height(24)
      Column() {
        Text("200米")
          .fontSize(12)
          .fontColor("#1f2642")
