This NuGet is in pre-release, and adding it to an application now means that it’s quite likely that an application-breaking change could be added to the package before initial release, giving you something else to handle.This is a cleaner way to determine current orientation.(view: background, left: 0, right: 1, top: 0, bottom: 5) If (this.width != width || this.height != height) Protected override void OnSizeAllocated(double width, double height)īase.OnSizeAllocated(width, height) //must be called Public partial class OnSizeAllocatedRearrangePage : ContentPageīack.Command = new Command(() => Navigation.PopModalAsync()) Then in OnSizeAllocated, I determined the orientation and set up the grid accordingly. In my implementation, I defined a grid in the xaml, along with the elements for each component, giving them appropriate names. From there, you can rearrange the layout however you like. You then override the OnSizeAllocated method in the code-behind for the page, manaually checking if width is greater than height to determine if the device is now in landscape or portrait. This way of handling orientation change involves setting up the view using the xaml, being sure to give the elements names. This is the recommended implementation pulled right from the Xamarin.Forms documentation. I noted the heavy-lifting code, as well as the pros and cons of each implementation. I then created a page based on these designs, using each implementation of orientation-handling that I researched. I specifically made these designs so that the transition between orientations could not be achieved using the built-in orientation-handling approach from Xamarin.Forms. Capacitor supports this through the cordova-plugin-screen-orientation plugin: Then, use the lock and unlock methods available on : See the Orientation Plugin Docs for the full range of possible. To test each of these implementations, I designed an example page with different layouts for portrait and landscape orientations. Many apps need to support multiple orientations, with the ability to lock orientations occasionally depending on the content. Unfortunately, these solutions are designed for very basic views, and they did not work for the complex design of views for our application.Īfter some research and experimentation, here are four methods I found to handle orientation changes in Xamarin.Forms, along with the final method we are using in our application. Most of these solutions involve using existing layouts and adjusting them so the view looks good (but the same) in both portrait and landscape. Its docs include an entire page on ways to handle orientation changes. The Xamarin.Forms framework has some basic functionality built in to handle transitions between orientations. I have been working on a project for a cross-platform mobile application using Xamarin.Forms, and my team has found it surprisingly difficult to determine the best way to handle orientation changes in the application.
