UI rolled up when keyboard appears - MAUI

It is my definition for xaml:

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="*"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>
    <Entry Placeholder="Write text..."/>
    <Button Text="Button" Grid.Row="1" VerticalOptions="End" />
</Grid>

When I click on control Entry and keyboard is visable. My interface is rolled up:

I can fix it by remove all stars from RowDecinition Height but setting the value rigidly causes that it does not adapt to all screens.

Is it possible to turn off roll up interface when keyboard is visable?

You can try to set the Application.WindowSoftInputModeAdjust attached property to Pan.

Please refer to the following code:

<?xml version = "1.0" encoding = "UTF-8" ?> 
<Application xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:local="clr-namespace:MauiApp"                 
             xmlns:android="clr-namespace:Microsoft.Maui.Controls.PlatformConfiguration.AndroidSpecific;assembly=Microsoft.Maui.Controls"
             android:Application.WindowSoftInputModeAdjust="Pan"
             x:Class="MauiApp0207.App">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Resources/Styles/Colors.xaml" />
                <ResourceDictionary Source="Resources/Styles/Styles.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

For more information,you can check Soft keyboard input mode on Android.

Update

In IOS, you can try to obtain keyboard's frame via UIKeyboard.FrameEndUserInfoKey and calculate the height that need to change.

NSValue result = (NSValue)args.Notification.UserInfo.ObjectForKey(new NSString(UIKeyboard.FrameEndUserInfoKey));

CGSize keyboardSize = result.RectangleFValue.Size;

private void Entry_Focused(object sender, FocusEventArgs e)
{
    if (DeviceInfo.Current.Platform == DevicePlatform.iOS)
    {
       NFloat bottom;
        try
        {
             UIWindow window = UIApplication.SharedApplication.Delegate.GetWindow();
                bottom = window.SafeAreaInsets.Bottom;
        }
        catch
        {
             bottom = 0;
        }
        var heightChange = (keyboardSize.Height - bottom);
        layout.TranslateTo(0, originalTranslationY.Value - heightChange, 50);
    }
}

private void Entry_Unfocused(object sender, FocusEventArgs e)
{
    if (DeviceInfo.Current.Platform == DevicePlatform.iOS)
    {
        layout.TranslateTo(0, 0, 50);
    }
}

in MainActivity.cs:

protected override void OnCreate(Bundle savedInstanceState)
{
...
App.Current.On<Microsoft.Maui.Controls.PlatformConfiguration.Android>().UseWindowSoftInputModeAdjust(WindowSoftInputModeAdjust.Pan);

...
}
