如何使用自定义图标在 React Native Mapbox 中执行集群。
我已经检查了 mapbox react native 的 GitHub 页面上给出的地震聚类示例。但我需要一些不同的东西，比如我需要使用自定义图标进行聚类。我在地图上有两种类型的数据/点，一种是用户，另一种是事件，它们都有不同的图标，所以我需要在集群中呈现这些自定义图标。
同样点击该图标，我需要在该图标后面显示一个脉冲动画。有什么可能的方法吗？
这是我实现 mapbox 的代码：-
<MapboxGL.MapView
ref={(ref) => this.map = ref}
showUserLocation={store.homeStore.locationAlowed}
zoomLevel={11}
pitch={45}
centerCoordinate={[store.userStore.longitude, store.userStore.latitude]}
userTrackingMode={MapboxGL.UserTrackingModes.follow}
styleURL={MapboxGL.StyleURL.Street}
style={{
position: store.homeStore.mapPosition,
top: 0,
left: 0,
right: 0,
bottom: 0,
}}
logoEnabled={false}
compassEnabled={false}
attributionEnabled={false}
onDidFinishRenderingMapFully={() => this.map.takeSnap(true).then((resp) => {
if (resp) {
store.homeStore.mapImageSource = resp;
}
})}
onPress={this.onMapPress.bind(this)}>
{store.homeStore.setLocationOnMap && store.homeStore.eventData.length > 0 ?
store.homeStore.eventData.map((prop, key) => {
return (
<MapboxGL.PointAnnotation
key={prop.id}
id={prop.id}
coordinate={[parseFloat(prop.evt_longitude), parseFloat(prop.evt_latitude)]} >
<TouchableOpacity onPress={this.selectEventOnMap.bind(this, prop)} style={{ height: vh * 0.109 }}>
<View style={styles.likesContainer}>
<Image source={require('../Images/ic_home_event_likes.png')}
style={[styles.heartImage, prop.event_likes > 999 ? { marginLeft: vw * 0.018 } :
prop.event_likes > 9 ? { marginLeft: vw * 0.036 } : { marginLeft: vw * 0.049 }]} />
<Text style={[styles.likesText, prop.event_likes < 10 ? { marginLeft: 2 } : '']}>
{prop.event_likes > 999 ? (Math.round(prop.event_likes / 1000) + " k") : prop.event_likes}</Text>
</View>
<Image source={require('../Images/ic_home_inactive_event_pin.png')}
style={{
height: vh * 0.098, width: vw * 0.15, marginTop: vh * 0.017,
tintColor: (prop.userid == store.userStore.id ? Colors.Blue : Colors.warmPink)
}} />
<Image source={this.getImageSource(prop.evt_category)}
style={{
height: vh * 0.041, width: vw * 0.077,
top: vh * 0.035, left: vw * 0.038, position: 'absolute'
}} />
{prop.selected && <Pulse style={{ zIndex: -1, position: 'absolute', top: -((vh * 0.109) / 3) }}
color={Colors.warmPink} numPulses={6} diameter={100} speed={18} duration={1000} />}
</TouchableOpacity>
</MapboxGL.PointAnnotation>
);
}) : null}
{store.homeStore.setLocationOnMap && store.homeStore.peopleData.length > 0 ?
store.homeStore.peopleData.map((prop, key) => {
return (
<MapboxGL.PointAnnotation
key={prop.userid}
id={prop.userid}
coordinate={[parseFloat(prop.longitude), parseFloat(prop.latitude)]} >
<TouchableOpacity onPress={() => { store.homeStore.showProfileCard = true; store.homeStore.userData = prop; }}>
<View style={{
height: vw * 0.130, width: vw * 0.130, borderRadius: (vw * 0.130) / 2,
backgroundColor: Colors.Blue, alignItems: 'center', justifyContent: 'center'
}}>
<AsyncImage source={{ uri: prop.image }}
style={{
height: vw * 0.122, width: vw * 0.122, borderRadius: (vw * 0.122) / 2
}} placeholderColor='#b3e5fc' />
</View>
</TouchableOpacity>
</MapboxGL.PointAnnotation>
);
}) : null}
{this.renderRoute()}
{/* <MapboxGL.ShapeSource

clusterRadius={50}
clusterMaxZoom={14}

这是json数据：-

使用 pointAnnotations 我可以在地图上显示点，但这种方式不会在 mapbox 上执行聚类。如果我尝试使用 shapesource 图层和 json 数据通过聚类在地图上制作点，那么我不知道如何使用我的自定义图标。我还需要在点击该自定义引脚时触发一个点击事件，并在该点后面显示脉冲加载动画。
请看一下屏幕截图，我还需要对集群做些什么。屏幕截图仅显示未发生聚类的点注释。
