错误/S：
e：file：/D：/Android_Studio_Projects/Live_Route/app/src/main/java/com/example/liveroute/MapsActivity.kt：55：9意外覆盖：以下声明具有相同的JVM签名（onLocationResult（Lcom/google/android/gms/location/LocationResult;）V）：fun onLocationResult（p0：LocationResult）：Unit defined in com. example. liveroute. MapsActivity. <no name provided> fun onLocationResult（locationResult：LocationResult？）：Unit defined in com. example. liveroute. MapsActivity. <no name provided>
当我在乐趣之前添加覆盖时，比如：
private val locationCallback = object : LocationCallback() {
override fun onLocationResult(locationResult: LocationResult?) {
locationResult?.lastLocation?.let { location ->
// Handle the new location here
val newLocation = LatLng(location.latitude, location.longitude)
updateMarkerPosition(newLocation)
}
}
}型
我就会在超驰上出错
'onLocationResult'不覆盖任何内容

错误“onLocationResult overrides nothing”是因为您忘记在覆盖中调用
super.onLocationResult()而导致的。因此，根据您的情况，添加
super调用。字符串
记住在覆盖中包含
super调用。编辑

删除函数参数中
LocationResult的可空值（?符号）。同样，这样做，你不必调用
super.onLocationResult()。你可以从官方文档中找到更多关于super和classes的信息。
