启用浅色主题时更改应用程序栏上的背景

Question

Hi i have this problem with my applicationbar. When i change the theme to light the icons turns to black, can I prevent this or can I change the backgroundcolor to something else when light theme is on.

Now i have a purple background all the time so either change the icons or background.

Any ideas for this?

For Detect the Dark or Light theme color, you can use

bool DarkThemeUsed ()
{ 
     return Visibility.Visible ==   (Visibility)Application.Current.Resources["PhoneDarkThemeVisibility"];
}

bool LightThemeUsed() 
{
     return Visibility.Visible == (Visibility)Application.Current.Resources["PhoneLightThemeVisibility"];
}

Source is developer.nokia.com : On this website, you've many idea and solution for little problem on windows phone :D

You can just test if your phone use the dark or the light them just when you started your application ( on your App.xaml.cs):

private void Application_Launching(object sender, LaunchingEventArgs e)
{
    DetectUserTheme();
}

private void DetectUserTheme()
{
    if(LightThemeUsed())
    {
        // Adapt your icons, background for the light theme.
        return;
    }

    // Adapt your icons, background for the dark theme. 
}

You can also use the color accent, define by the user :

 Color currentAccentColorHex = 
        (Color)Application.Current.Resources["PhoneAccentColor"];

And you can use it in your application for few color text or element...
