1.申明三个包

  • esri/layers/GraphicsLayer
  • esri/Graphic

  • esri/geometry/Point
    2.申明GraphicsLayer并且add到map外面
    3.初始化图片标记点并且add到GraphicsLayer

    async ShowLocation() {    let that = this    const Graphic = await arcgisPackage.Graphic    const GraphicsLayer = await arcgisPackage.GraphicsLayer    const Point = await arcgisPackage.Point        let layer = new GraphicsLayer()    that.map.add(layer)    var symbol = {      type: "picture-marker",      url: require('../../../assets/img/onepicture/ta.png'),//图片地址      width: "64px",      height: "64px"    };    var point = new Point(103.880812,27.802255);    var gp = new Graphic(point,symbol);    layer.graphics.add(gp);  },
