Get current screen width in xamarin forms

Question

I am creating one Xamarin Forms project and I got stuck in finding the current screen width according to the different device.

I know how it can be done in android and ios but need a way to find the width in portable.

Answer 1

You can try this Application.Current.MainPage.Width in my case this worked and i am able to find the device width in portable project itself.

Answer 2

I know it is an old thread but worth mentioning that recently Xamarin.Essentials NuGet pakage was released and there is a useful class DeviceDisplay in there that should handle this task for you.

The documentation can be found here.

Usage example:

// Get Metrics
var mainDisplayInfo = DeviceDisplay.MainDisplayInfo;

// Orientation (Landscape, Portrait, Square, Unknown)
var orientation = mainDisplayInfo.Orientation;

// Rotation (0, 90, 180, 270)
var rotation = mainDisplayInfo.Rotation;

// Width (in pixels)
var width = mainDisplayInfo.Width;

// Width (in xamarin.forms units)
var xamarinWidth = width / mainDisplayInfo.Density;

// Height (in pixels)
var height = mainDisplayInfo.Height;

// Screen density
var density = mainDisplayInfo.Density;

Answer 3

Common code (in App.xaml.cs)

public static int ScreenHeight {get; set;}
public static int ScreenWidth {get; set;}

Android part (in MainActivity.cs, in the OnCreate method)

App.ScreenHeight = (int) (Resources.DisplayMetrics.HeightPixels / Resources.DisplayMetrics.Density);
App.ScreenWidth = (int) (Resources.DisplayMetrics.WidthPixels / Resources.DisplayMetrics.Density);

iOS part (in AppDelegate.cs, in the FinishedLaunching method)

App.ScreenHeight = (int)UIScreen.MainScreen.Bounds.Height;
App.ScreenWidth = (int)UIScreen.MainScreen.Bounds.Width;

So App.ScreenHeight and App.ScreenWidth will be initialized when the App will be launched, then you will be able to use them anywhere in the common code.
