Question

我正在用windev mobile构建一个Android应用程序。我可以使用描述地址和城市的变量来打开地图，但我似乎无法以相同的方式在地图上获得标记。 ggladdresstocoordinates并不适用于windev mobile。

我目前的代码是：

//MapDisplayPosition(MAP_Worklocation, Street, City, country)
MyAddress is Address
MyAddress..Street = gnWorkaddress
MyAddress..City = gnWorkplace
MyAddress..Country = "Netherlands"

// Centers the map displayed by the "MAP_Position" control from an address
MapDisplayPosition(MAP_Worklocation, MyAddress)

MAP_Worklocation..Zoom = 17

mymarker is Marker
mymarker..Position = MyAddress
MapAddMarker(MAP_Worklocation, mymarker)

Answer 1

使用MapDisplayPosition后，地图将居中于搜索位置，然后，如果您使用MapGetPosition，它将返回坐标。从Windev帮助：MapGetPosition-“返回当前在地图控件中显示的地图中心的点的地理位置。”

MyPosition is geoPosition
MyPosition = MapGetPosition(MAP_Worklocation)
EDT_Latitude=MyPosition..Latitude
EDT_Longitude=MyPosition..Longitude

Answer 2

我认为问题出在MapDisplayPosition函数中，第二个参数必须是geoPostiion变量，如您所见in the help或它可能是带有地址的字符串，您是否尝试过：

sAddress is string = gnWorkaddress + ", " + gnWorkplace + ", " + "Netherlands"

MapDisplayPosition(MAP_Worklocation, sAddress)

此外，您无法将Address分配给..Position，而需要geoPosition变量；使用MapDisplayPosition将地图居中后，您可以使用以下方法检索位置：

TmpPos is geoPosition
TmpPos = MapGetPosition(MAP_Worklocation)

然后添加标记：

MyMarker is Marker
MyMarker..Position = TmpPos
MyMarker..ActionClick = ProcMarkerClick

MapAddMarker(MAP_Worklocation, MyMarker)

尝试一下，我个人发现了一个不同的解决方法，因为在注册过程中，发件人和地址（街道，邮政编码，城市...）都写了，我需要使用gps代码，所以我使用了Google Maps Apis：< / p>

oQuery  is httpRequest

// Replace blank spaces with +, for URL.
sTempStreet is string = Replace(MyStreet," ","+")
sTempCity is string = Replace(MyCity," ","+")

oQuery..URL     = "https://maps.googleapis.com/maps/api/geocode/json?address="+sTempStreet+",+"+sTempCity+"+"+stTempZIP+"+"+stTempCountry+",+stTempState&key=*<yourapikeyhere>*"
oQuery..Method  = httpGet

oResponse is httpResponse
oResponse = HTTPSend(oQuery)

vInfo       is Variant
vInfo = JSONToVariant(oResponse..Content)

sGPSLatitude = vInfo.results[1].geometry.location.lat
sGPSLongidute = vInfo.results[1].geometry.location.lng

Windev移动，地址到坐标
