当我选择一个联系人到达我的应用程序中的位置时,它会显示一个带有位置图标的地图,但是在地图中间不在卷轴位置,以便MainActivity中的代码:
fun getUserLocation() {
var myLocation = MyLocationListener()
val locationManager = getSystemService(Context.LOCATION_SERVICE) as LocationManager
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 3, 3f, myLocation)
//list sent to request
var userData=UserData(this)
val myPhoneNumber=userData.loadPhoneNumber()
databaseRef!!.child("Users").child(myPhoneNumber).child("request").addValueEventListener(
object :ValueEventListener{
override fun onDataChange(p0: DataSnapshot?) {
if (MainActivity.myLocation==null) return
//get datatime
val df = SimpleDateFormat("yyyy/MM/dd HH:MM:ss")
val date = Date()
databaseRef!!.child("Users").child(myPhoneNumber).child("location").child("lat").setValue(MainActivity.myLocation!!.latitude)
databaseRef!!.child("Users").child(myPhoneNumber).child("location").child("log").setValue(MainActivity.myLocation!!.longitude)
databaseRef!!.child("Users").child(myPhoneNumber).child("location").child("lastOnline").setValue(df.format(date).toString())
}

您需要从回调侦听器获得协调。
所以在位置监听器里面列出发送请求:
inner class MyLocationListener: LocationListener {
constructor():super(){
AccesLocation=true
myLocation= Location("me")
myLocation?.longitude=0.0
myLocation?.latitude=0.0
}
override fun onLocationChanged(location: Location?) {
myLocation=location
//list sent to request
var userData=UserData(this)
val myPhoneNumber=userData.loadPhoneNumber()
databaseRef?.child("Users").child(myPhoneNumber).child("request").addValueEventListener(
object :ValueEventListener{
override fun onDataChange(p0: DataSnapshot?) {
if (MainActivity.myLocation==null) return
//get datatime
val df = SimpleDateFormat("yyyy/MM/dd HH:MM:ss")
val date = Date()
databaseRef?.child("Users").child(myPhoneNumber).child("location").child("lat").setValue(loction?.latitude)
databaseRef?.child("Users").child(myPhoneNumber).child("location").child("log").setValue(loction?.longitude)
databaseRef?.child("Users").child(myPhoneNumber).child("location").child("lastOnline").setValue(df.format(date).toString())
}
}
...
};
尝试使用?插入 !!
