google-maps - react-google-maps 自定义标记图标

Question

目前，我已经成功地将 map 组件渲染为可重用组件，使用 InfoModal 显示图标，但是，标准的红色谷歌地图图标我没有修改，我想自己创建一个自定义图标。我不确定 ES6 和 JSX 语法我需要做什么。我查看了 react-google-maps 问题并试图查看是否有任何当前或更新的 Material 可以做到这一点(这可能很简单)，但我不确定 react-google-maps 是否有自定义的东西以插件或正确格式创建标记。

import React, { Component } from 'react'
import { withGoogleMap, GoogleMap, Marker, InfoWindow } from 'react-google-maps'
import { DEFAULT_MARKER } from '../../constants/mapDefaults'

const MapGoogleMap = withGoogleMap(props => (
  <GoogleMap
    defaultZoom={16}
    center={props.center}
  >
    {props.markers.map((marker, index) => (
      <Marker
        key={index}
        position={marker.position}
        onClick={() => props.onMarkerClick(marker)}
      >

        {marker.showInfo && (
          <InfoWindow onCloseClick={() => props.onMarkerClose(marker)}>
            <div>{marker.infoContent}</div>
          </InfoWindow>
        )}
      </Marker>
    ))}
  </GoogleMap>
))

export default class Map extends Component {
  state = {
    center: {
      lat: 28.3421135,
      lng: -80.6149092
    },

    markers: [
      {
        position: new google.maps.LatLng(28.3431165, -80.6135908),
        showInfo: false,
        infoContent: (
          <svg
            id="Layer_1"
            xmlns="http://www.w3.org/2000/svg"
            width="16"
            height="16"
            viewBox="0 0 16 16"
          >
            <path

            />
          </svg>
        )
      }, DEFAULT_MARKER
    ]
  }

  handleMarkerClick = this.handleMarkerClick.bind(this);
  handleMarkerClose = this.handleMarkerClose.bind(this);

  handleMarkerClick (targetMarker) {
    this.setState({
      markers: this.state.markers.map(marker => {
        if (marker === targetMarker) {
          return {
            ...marker,
            showInfo: true
          }
        }
        return marker
      })
    })
  }

  handleMarkerClose (targetMarker) {
    this.setState({
      markers: this.state.markers.map(marker => {
        if (marker === targetMarker) {
          return {
            ...marker,
            showInfo: false
          }
        }
        return marker
      })
    })
  }

  render () {
    return (
      <MapGoogleMap
        containerElement={
          <div style={{ height: `500px` }} />
        }
        mapElement={
          <div style={{ height: `500px` }} />
        }
        center={this.state.center}
        markers={this.state.markers}
        onMarkerClick={this.handleMarkerClick}
        onMarkerClose={this.handleMarkerClose}
      />
    )
  }
}

Answer 1

这就是我解决的方法

let iconMarker = new window.google.maps.MarkerImage(
                    "https://lh3.googleusercontent.com/bECXZ2YW3j0yIEBVo92ECVqlnlbX9ldYNGrCe0Kr4VGPq-vJ9Xncwvl16uvosukVXPfV=w300",
                    null, /* size is determined at runtime */
                    null, /* origin is 0,0 */
                    null, /* anchor is bottom center of the scaled image */
                    new window.google.maps.Size(32, 32)
                );
                return(
                    <Marker
                        icon={iconMarker}
                        key={marker.id}
                        onClick={onClick}
                        position={{ lat: parseInt(marker.latitude), lng: parseInt(marker.longitude)}}>
                        {props.selectedMarker === marker &&
                        <InfoWindow>
                            <div style={{'color':'black'}}>
                               Shop {marker.name} {stretTexte}
                            </div>
                        </InfoWindow>}
                    </Marker>
                )
