I'm trying do a simple app in Xamarin where I can see the current weather in my city. But I cant seem to get it right.. I've got the api from openweathermap.org, where in the url I'm searching for my city's coordinates. To get the classes for my "OpenWeather" class, I used json2csharp, to generate my class.
I want to display the city name, weatherdescription and the coordinates.
I'll post the code I got so far:
MainPage.xaml.cs:
public partial class MainPage : ContentPage
{
public MainPage()
{
InitializeComponent();
GetWeather();
}
public async void GetWeather()
{
try
{
string URL = "http://api.openweathermap.org/data/2.5/weather?lat=58.34&lon=11.94&appid=((((((MY API KEY))))))))))))";
HttpClient httpClient = new HttpClient();
HttpResponseMessage response = await httpClient.GetAsync(new Uri(URL));
if (response.IsSuccessStatusCode)
{
var content = await response.Content.ReadAsStringAsync();
var weatherList = JsonConvert.DeserializeObject<RootObject>(content);
//Databind the list
lstWeather.ItemsSource = weatherList;
}
}
catch (Exception ex)
{
//ToDo Give errormessage to user and possibly log error
System.Diagnostics.Debug.WriteLine(ex.ToString());
}
}
}
MainPage.xaml:
<ProgressBar IsEnabled="True"></ProgressBar>
<ListView x:Name="lstWeather">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<StackLayout>
<StackLayout Orientation="Vertical">-->
<Label Text="{Binding name}" />
<Label Text="{Binding desciption}" Margin="20,0,0,0"/>
<Label Text="{Binding lon}" Margin="20,0,0,0"/>
<Label Text="{Binding lat}" Margin="20,0,0,0"/>
</StackLayout>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
