Soft Keyboard Input Mode on Android

Download Sample Download the sample

This Android platform-specific is used to set the operating mode for a soft keyboard input area, and is consumed in XAML by setting the Application.WindowSoftInputModeAdjust attached property to a value of the WindowSoftInputModeAdjust enumeration:

<Application ...
             xmlns:android="clr-namespace:Xamarin.Forms.PlatformConfiguration.AndroidSpecific;assembly=Xamarin.Forms.Core"
             android:Application.WindowSoftInputModeAdjust="Resize">
  ...
</Application>

Alternatively, it can be consumed from C# using the fluent API:

using Xamarin.Forms.PlatformConfiguration;
using Xamarin.Forms.PlatformConfiguration.AndroidSpecific;
...

App.Current.On<Android>().UseWindowSoftInputModeAdjust(WindowSoftInputModeAdjust.Resize);

The Application.On<Android> method specifies that this platform-specific will only run on Android. The Application.UseWindowSoftInputModeAdjust method, in the Xamarin.Forms.PlatformConfiguration.AndroidSpecific namespace, is used to set the soft keyboard input area operating mode, with the WindowSoftInputModeAdjust enumeration providing two values: Pan and Resize. The Pan value uses the AdjustPan adjustment option, which doesn't resize the window when an input control has focus. Instead, the contents of the window are panned so that the current focus isn't obscured by the soft keyboard. The Resize value uses the AdjustResize adjustment option, which resizes the window when an input control has focus, to make room for the soft keyboard.

The result is that the soft keyboard input area operating mode can be set when an input control has focus:
