如何个性化定制Android Compose版Google Maps组件?
基于Android Compose的Google Maps SDK UI定制问题
我正在开发一个基于Android Compose和Google Maps SDK的项目,需要对地图的所有UI进行定制,包括:
- 修改标记样式
- 移除默认地点标记
- 更改字体样式
- 自定义定位按钮
我了解旧版Google Maps库可实现这些功能,但不清楚新版Compose库的操作方法。查阅了Google官方文档,但内容十分匮乏,目前仅找到使用旧库的解决方案,可新库使用起来更便捷,不想退回去用旧库。
以下是我在Composable中实现GoogleMap的代码:
@Composable fun DiscoverContent( mapState: MapState, setupClusterManager: (Context, GoogleMap) -> ZoneClusterManager, calculateZoneViewCenter: () -> LatLngBounds, onClusterClicked: (ZoneClusterItem) -> Unit ) { val context = LocalContext.current val mapProperties = MapProperties(isMyLocationEnabled = mapState.lastKnownLocation != null) val cameraPositionState = rememberCameraPositionState() GoogleMap( modifier = Modifier.fillMaxSize(), properties = mapProperties, cameraPositionState = cameraPositionState, uiSettings = MapUiSettings() ) { val scope = rememberCoroutineScope() MapEffect(mapState.clusterItems) { map -> if (mapState.clusterItems.isNotEmpty()) { val clusterManager = setupClusterManager(context, map) map.setOnCameraIdleListener(clusterManager) map.setOnMarkerClickListener(clusterManager) clusterManager.setOnClusterClickListener { cluster -> val clusterItem = cluster.items.firstOrNull() clusterItem?.let { onClusterClicked(it) } true } map.setOnMapLoadedCallback { if (mapState.clusterItems.isNotEmpty()) { scope.launch { cameraPositionState.animate( update = CameraUpdateFactory.newLatLngBounds( calculateZoneViewCenter(), MAP_PADDING ) ) } } } } } }
