Android Question keystorevalue problem with latlng

[tufanv]

Hello

I use:

dim points as list
points.initialize
direction = gmap.AddPolyline
llPoint.Initialize(location1.Latitude, location1.Longitude) 
points.Add(llPoint)

I can store this list with
kvs.PutObject("example", listpoints)

and when i get the log of list poins i can see the latlng values:

(ArrayList) [lat/lng: (40.96685325,29.07294338), lat/lng: (40.96684747,29.07295137), lat/lng: (40.96683695,29.07292347), lat/lng: (40.96671902,29.07326131), lat/lng: (40.96671928,29.07324356), lat/lng: (40.9666991,29.07328743), lat/lng: (40.96676502,29.07314883), lat/lng: (40.96678631,29.07313557), lat/lng: (40.96670767,29.07326611), lat/lng: (40.96672245,29.07324716), lat/lng: (40.96671392,29.0732735)]

but later when i try to get the values with keystorevalue

dim listgetir as list  
listgetir.Initialize
    listgetir=kvs.GetObject("example")

i see that all the values of list are null so i cant add as polyline to my googlemap objects. Eurojam tried to help and said that it is because of the latlng type , when he stored the values as double he could list them. But to add to googlemap i still need them as latlng. How can i fix this ?

You will need to create your own custom type instead of LatLng.

Type MyLatLng (Latitude As Double, Longitude As Double)

Sub LatLngToMyLatLng (ll As LatLng) As MyLatLng
dim mll As MyLatLng
mll.Initialize
mll.Latitude = ll.Latitude
mll.Longitude = ll.Longitude
Return ml
End Sub

Erel I tried it now i can see in the logs the correct values instead of nulls but this time when i try to add them as polyline i get:
java.lang.ClassCastException: fv.speedometer.main$_mylatlng cannot be cast to com.google.android.gms.maps.model.LatLng

You will need to create your own custom type instead of LatLng.

Type MyLatLng (Latitude As Double, Longitude As Double)

Sub LatLngToMyLatLng (ll As LatLng) As MyLatLng
dim mll As MyLatLng
mll.Initialize
mll.Latitude = ll.Latitude
mll.Longitude = ll.Longitude
Return ml
End Sub

    listgetir=kvs.GetObject("example")
    LogColor(listgetir,Colors.Red)

        direction2=gmap.AddPolyline
        direction2.Color=Colors.red
        direction2.Points=listgetir

You will need to convert MyLatLng to LatLng before you can use them.

You will need to convert MyLatLng to LatLng before you can use them.

is converting needs a code again like you posted in previous message or will i just declare a new latlng and get them from the mylatlng ?

 

[Erel]

You will need to create a similar sub that converts between the two types. There isn't any special relation between them.

You will need to create a similar sub that converts between the two types. There isn't any special relation between them.

but latlng 's laitude and longitude values are read only unlike mylatlng

 

[Erel]

Sub MyLatLngToLatLng(mll As MyLatLng) As LatLng
 Dim ll As LatLng
 ll.Initialize(mll.Latitude, mll.Longitude)
 Return ll
End Sub
