kotlin - Google map Compose MyLocationButton 未显示

Question

我在 documentation 中遵循了有关如何使用 jetpack compose 显示谷歌地图的简单教程。 .

但是 MyLocationButton 仍然没有显示。

val singapore = LatLng(1.35, 103.87)
val cameraPositionState = rememberCameraPositionState {
    position = CameraPosition.fromLatLngZoom(singapore, 17f)
}
var uiSettings by remember { mutableStateOf(
    MapUiSettings(
       myLocationButtonEnabled = true,
       zoomControlsEnabled = false
    )
 ) }

 GoogleMap(
      modifier = Modifier.fillMaxSize(),
      cameraPositionState = cameraPositionState,
      uiSettings = uiSettings,
      onMyLocationButtonClick = {
         true
      }
 ) {
       Marker(
           state = MarkerState(position = singapore),
           title = "Singapore",
           snippet = "Marker in Singapore"
       )
 }

Answer 1

您必须添加 GoogleMap 的属性:

GoogleMap(properties = MapProperties(isMyLocationEnabled = true))
