[英]How to change pin icon on click in xamarin.forms.maps iOS c#
[英]Add pin on click Xamarin.Forms.Maps
我想在使用Xamarin.Forms.Maps單擊地圖上添加新的圖釘。 搜索后,我發現我必須使用TKCustomMap插件..但是它沒有顯示在地圖上..只是空白區域,這是我的代碼
double lit = 2.394;// double.Parse(Center.CenterLocationX);
double longt = 43.2352;// double.Parse(Center.CenterLocationY);
TK.CustomMap.Position position = new TK.CustomMap.Position(lit, longt);
TK.CustomMap.MapSpan span = TK.CustomMap.MapSpan.FromCenterAndRadius(position, TK.CustomMap.Distance.FromMiles(0.5));
TK.CustomMap.TKCustomMap map = new TK.CustomMap.TKCustomMap(span);
map.IsShowingUser = true;
map.MapType = TK.CustomMap.MapType.Street;
TK.CustomMap.TKCustomMapPin pin = new TK.CustomMap.TKCustomMapPin()
{
//Address = "Test",
//Label = "Test",
Position = position,
IsDraggable = true
//Type = PinType.SearchResult
};
map.MapClicked += (x, y) =>
{
SharedTools.MakeToast("Clicked");
};
//map.Pins.Add(pin);
map.Pins = new List<TK.CustomMap.TKCustomMapPin>() { pin };
map.MoveToMapRegion(span);
layout.Content = map;
我想解決這個問題,或任何其他想法在點擊時添加圖釘
我在演示中使用了您的代碼,結果如下圖所示(如果看不到google
,則應檢查API_KEY
,如果正確)。
<meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="API_KEY" />
然后,我改變了lit
37, longt
至-122和click.I添加PIN可以看到地圖,得到以下結果。 如果值合法,請檢查您的lit
和longt
有我的代碼。
public partial class MainPage : ContentPage
{
TK.CustomMap.TKCustomMap map;
TK.CustomMap.Position position;
public MainPage()
{
InitializeComponent();
//37,-122
double lit = 37;// double.Parse(Center.CenterLocationX);
double longt = -122;// double.Parse(Center.CenterLocationY);
position = new TK.CustomMap.Position(lit, longt);
TK.CustomMap.MapSpan span = TK.CustomMap.MapSpan.FromCenterAndRadius(position, TK.CustomMap.Distance.FromMiles(0.5));
map = new TK.CustomMap.TKCustomMap(span);
map.IsShowingUser = true;
map.MapType = TK.CustomMap.MapType.Street;
map.MapClicked += OnMapClicked;
Content = map;
}
private void OnMapClicked(object sender, TKGenericEventArgs<Position> e)
{
TK.CustomMap.TKCustomMapPin pin = new TK.CustomMap.TKCustomMapPin()
{
//Address = "Test",
//Label = "Test",
Position = position
,
IsDraggable = true
//Type = PinType.SearchResult
};
map.Pins = new List<TK.CustomMap.TKCustomMapPin>() { pin };
}
}
這是我的演示,希望能為您提供幫助。
