用法

基本用法

import { MapView } from 'react-native-baidumap-sdk'

render() {
  return <MapView center={{ latitude: 39.2, longitude: 112.4 }} />
}

显示卫星图

<MapView satellite />

监听地图事件

import { MapView } from 'react-native-baidumap-sdk'

render() {
  return (
    <MapView
      onLoad={() => console.log('onLoad')}
      onClick={point => console.log(point)}
      onStatusChange={status => console.log(status)}
    />
  )
}

定位并关联定位图层

import { MapView, Location } from 'react-native-baidumap-sdk'

await Location.init()
Location.addLocationListener(location => this.setState({ location }))
Location.start()

state = { location: null }

render() {
  return <MapView location={this.state.location} locationEnabled />
}

添加标记

<MapView>
  <MapView.Marker
    color="#2ecc71"
    title="This is a marker"
    onPress={this.onPress}
  />
</MapView>

添加自定义图片标记

<MapView>
  <MapView.Marker
    title="This is a image marker"
    image="flag"
    coordinate={{ latitude: 39, longitude: 113 }}
  />
</MapView>

添加自定义 View 标记

<MapView>
  <MapView.Marker
    icon={() => (
      <View>
        <Image source={image} />
        <Text>This is a custom marker</Text>
      </View>
    )}
  />
</MapView>

点聚合

onStatusChange = status => this.cluster.update(status)

renderMarker = item => (
  <MapView.Marker
    key={item.extra.key}
    coordinate={item.coordinate}
  />
)

render() {
  return (
    <MapView onStatusChange={this.onStatusChange}>
      <MapView.Cluster
        ref={ref => this.cluster = ref}
        markers={this.markers}
        renderMarker={this.renderMarker}
      />
    </MapView>
  )
}

显示热力图

points = [
  {
    latitude: 39,
    longitude: 113,
    intensity: 16,
  },
  ...
]

<MapView>
  <MapView.HeatMap
    points={this.points}
    radius={20}
    opacity={0.5}
  />
</MapView>

地理编码/逆地理编码

import { Geocode } from 'react-native-baidumap-sdk'

const searchResult = await Geocode.search('海龙大厦')
const reverseResult = await Geocode.reverse({ latitude: 39, longitude: 113 })
