 <Label x:Name="labelGPSTrack"/> 

    <Label Text=""/>     

   </StackLayout>


Step 3 :


Use the following code in C# file :

namespace PluginDemo
{
    public partial class GeolocatorPage : ContentPage
    {
        public GeolocatorPage()
        {
            InitializeComponent(); buttonGetGPS.Clicked += async (sender, args) =>
            {
            try
            {
                var locator = CrossGeolocator.Current; locator.DesiredAccuracy = 1000; labelGPS.Text = "Getting gps";
                var position = await locator.GetPositionAsync(timeoutMilliseconds: 10000);
                if (position == null) { labelGPS.Text = "null gps :("; return; }
                labelGPS.Text = string.Format("Time: {0} \nLat: {1} \nLong: {2} \nAltitude: {3} \nAltitude Accuracy: {4} \nAccuracy: {5} \nHeading: {6} \nSpeed: {7}", position.Timestamp, position.Latitude, position.Longitude, position.Altitude, position.AltitudeAccuracy, position.Accuracy, position.Heading, position.Speed);
            }
            catch //(Exception ex)                {                   // Xamarin.Insights.Report(ex);                   // await DisplayAlert("Uh oh", "Something went wrong, but don't worry we captured it in Xamarin Insights! Thanks.", "OK");                }            };
            buttonTrack.Clicked += async (object sender, EventArgs e) =>
            {
            try { if (CrossGeolocator.Current.IsListening) { await CrossGeolocator.Current.StopListeningAsync(); labelGPSTrack.Text = "Stopped tracking"; buttonTrack.Text = "Stop Tracking"; } else { if (await CrossGeolocator.Current.StartListeningAsync(30000, 0)) { labelGPSTrack.Text = "Started tracking"; buttonTrack.Text = "Track Movements"; } } }
            catch //(Exception ex)                {                    //Xamarin.Insights.Report(ex);                   // await DisplayAlert("Uh oh", "Something went wrong, but don't worry we captured it in Xamarin Insights! Thanks.", "OK");                }            };        }
        protected override void OnAppearing() { base.OnAppearing(); try { CrossGeolocator.Current.PositionChanged += CrossGeolocator_Current_PositionChanged; CrossGeolocator.Current.PositionError += CrossGeolocator_Current_PositionError; } catch { } }
        void CrossGeolocator_Current_PositionError(object sender, Plugin.Geolocator.Abstractions.PositionErrorEventArgs e)
        {
            labelGPSTrack.Text = "Location error: " + e.Error.ToString();
        }
        void CrossGeolocator_Current_PositionChanged(object sender, Plugin.Geolocator.Abstractions.PositionEventArgs e)
        {
            var position = e.Position; labelGPSTrack.Text = string.Format("Time: {0} \nLat: {1} \nLong: {2} \nAltitude: {3} \nAltitude Accuracy: {4} \nAccuracy: {5} \nHeading: {6} \nSpeed: {7}", position.Timestamp, position.Latitude, position.Longitude, position.Altitude, position.AltitudeAccuracy, position.Accuracy, position.Heading, position.Speed);
        }
        protected override void OnDisappearing()
        {
            base.OnDisappearing();
            try { CrossGeolocator.Current.PositionChanged -= CrossGeolocator_Current_PositionChanged; CrossGeolocator.Current.PositionError -= CrossGeolocator_Current_PositionError; } catch { }
        }
    }
}

ScrollView in xamarin forms

Image
An element capable of scrolling if it's Content requires. ScrollView contains layouts and enables them to scroll offscreen. ScrollView is also used to allow views to automatically move to the visible portion of the screen when the keyboard is showing. Note: ScrollViews should not be nested. In addition, ScrollViews should not be nested with other controls that provide scrolling, like ListView and WebView. A ScrollView is easy to define. In XAML: <ContentPage.Content> <ScrollView> <StackLayout> <BoxView BackgroundColor="Red" HeightRequest="600" WidthRequest="150" /> <Entry /> </StackLayout> </ScrollView> </ContentPage.Content> The same definition in code: var scroll = new ScrollView(); Content = scroll; var stack = new StackLayout(); stack.Children.Add(new BoxView { BackgroundColor = Color.Red, HeightRequest = 600, WidthRequest = 600 });
