ParticleOverlay (mapslibrary API)

java.lang.Object
- com.amap.api.maps.model.BaseOverlay
- - com.amap.api.maps.model.particle.ParticleOverlay

```
public class ParticleOverlay
extends BaseOverlay
```
粒子效果，可以在地图上实现下雨、下雪和雾霾等天气效果，也可以通过开放的接口自定义建议在AMap.OnMapLoadedListener 之后调用
Particle effects can simulate weather conditions like rain, snow, and haze on the map, and can also be customized through open APIs. It is recommended to call after AMap.OnMapLoadedListener.

从以下版本开始:

6.5.0
