问题描述
当您加载地图然后移动地图并立即放大时,我的应用程序在模拟器中崩溃.香港专业教育学院尝试了许多我在互联网上发现的不同误解,因为我得到的唯一错误是灾难性故障,没有进一步的信息(没有行号或任何错误信息)
My app crashes in the emulator when u load the map and then move the map and zoom in instantly. ive tried many different soulutions i found on the internet as the only error i get is Catastrophic Failure and no further information (no line number or any error information whatsoever)
C#代码
public sealed partial class MapView : MvxWindowsPage
{
double lat=0;
double lon=0;
Geolocator gl = new Geolocator();
MapIcon Micon = new MapIcon();
Geopoint blo;
public MapView()
{
this.InitializeComponent();
Windows.Phone.UI.Input.HardwareButtons.BackPressed += HardwareButtons_BackPressed;
GetInitialPosition();
}
private MapViewModel ViewModel
{
get { return DataContext as MapViewModel; }
}
private bool HasViewModel { get { return ViewModel != null; } }
void HardwareButtons_BackPressed(object sender, Windows.Phone.UI.Input.BackPressedEventArgs e)
{
e.Handled = true;
Windows.Phone.UI.Input.HardwareButtons.BackPressed -= HardwareButtons_BackPressed;
ViewModel.NavigateFirst();
}
async void GetInitialPosition()
{
gl.DesiredAccuracyInMeters = 500;
gl.DesiredAccuracy = PositionAccuracy.Default;
IAsyncOperation<Geoposition> locationTask = null;
try
{
Geoposition gp = await gl.GetGeopositionAsync(
maximumAge: TimeSpan.FromMinutes(5),
timeout: TimeSpan.FromSeconds(10)
);
//LatitudeTextBlock.Text = geoposition.Coordinate.Latitude.ToString("0.00");
//LongitudeTextBlock.Text = geoposition.Coordinate.Longitude.ToString("0.00");
}
finally
{
DispatcherTimer dt = new DispatcherTimer();
dt.Interval = new TimeSpan(0, 0, 5);
dt.Tick += (sender, e) => ProgBar.Visibility = Visibility.Collapsed;
dt.Tick += (sender, e) => ProgBar.IsEnabled = false;
dt.Start();
}
}
}
}
Xaml:
<views:MvxWindowsPage
xmlns:Maps="using:Windows.UI.Xaml.Controls.Maps"
x:Class="Etgarim.Views.MapView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:local="using:Etgarim.Views"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:views="using:Cirrious.MvvmCross.WindowsCommon.Views"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid>
<Maps:MapControl x:Name="OmNaMap" MapServiceToken="..."/>
<!--Visibility="Visible" Center="{Binding blo}"-->
<ProgressBar x:Name="ProgBar" Height="667"/>
</Grid>
推荐答案
移动地图控件和进度条,使它们不会重叠,这应该可以解决问题.
Move the map control and the progress bar so they not over lapping, this should resolve the issue.
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="667"></RowDefinition>
<RowDefinition Height="*"></RowDefinition>
</Grid.RowDefinitions>
<ProgressBar Grid.Row="0" x:Name="ProgBar" />
<Maps:MapControl Grid.Row="1" x:Name="OmNaMap" MapServiceToken="..."/>
<!--Visibility="Visible" Center="{Binding blo}"-->
</Grid>
