Noticed how these apps use the Status Bar on the top?
I think that is very efficient use of the screen space, while not really hiding the status bar. But until I saw how the mail client app does that, I didn’t really figure out how I could do that in my apps. The solution turns out to be extremely simple!
Using the status bar for the title of your app. (AKA., more screen space for the content)
Summary: Set the text property of the progress bar, which is a part of the status bar.
If you look at the MSDN documentation for the StatusBar class, you’ll see just a handful of properties and methods that you can work with. When I saw how the email client on WP makes use of the status bar, it was obvious how the Bing apps use it!
You can try this piece of code in the OnLaunched event handler in your App.xaml.cs:
// Set the background color of the status bar, and DON'T FORGET to set the opacity!
var statusBar = Windows.UI.ViewManagement.StatusBar.GetForCurrentView();
statusBar.BackgroundColor = (App.Current.Resources["PhoneAccentBrush"] as SolidColorBrush).Color;
statusBar.BackgroundOpacity = 1;
// Set the text on the ProgressIndicator, and show it.
statusBar.ProgressIndicator.Text = "My cool app";
// If the progress value is null (which is the default value), the progress indicator is in an
indeterminate state (dots moving from left to right).
// Set it to 0 if you don't wish to show the progress bar.
statusBar.ProgressIndicator.ProgressValue = 0;
So, the key thing is to set the Text property of the ProgressIndicator on the StatusBar, and call the ShowAsync method. Setting the background color and opacity of the status bar is stuff that you could choose to do if you have a particular theme for the app (or choose the phone accent brush).
And that’s it, really! Here are the screenshots of what it looks like with different themes on the phone.
Making use of the screen space of a transparent status bar
Say you have an app which has a photo viewer section. You would obviously want to use up as much screen space as possible, but may be also have some branding – at least the name of the app. Even if you followed all the steps above, and set the opacity of the status bar to 0, you would see something like this:
See how the Status Bar stays on top, even if you set the opacity to 0? That doesn’t look too good. What would be great is if we could have something like this:
To do this, we need to use the entire Window space available, including what is usually allocated for the status bar and the app bar.
So, use this piece code in the OnLaunched event handler in your App.xaml.cs:
// Set the desired bounds on the application view to use the core window, i.e., the entire screen (including app bar and status bar
var applicationView = Windows.UI.ViewManagement.ApplicationView.GetForCurrentView();
That’s it for today! Hope this helped.
