Как скрыть / закрыть SoftKeyboard в Xamarin Android?

Question

В моей программе есть стандартная клавиатура, которую я использую для «Вступления»

Однако я тестирую некоторые вещи, и в итоге я поставил IsEnabled = True, но когда программа переходит в Focus на этомEntry, по умолчанию появляется Android Softkeyboard, и я не хочу, чтобы он появлялся, когда я нажимаю Entry.

Как не отображать SoftKeyboard в Entry?

Answer 1

Настройка записи в родном андроиде может сделать это:

Во-первых, создав MyEntry

public class MyEntry : Entry
{
}

Во-вторых, используя в Xaml :

<ContentPage ...
    xmlns:local="clr-namespace:CustomRenderer;assembly=CustomRenderer"
    ...>
    ...
    <local:MyEntry Text="In Shared Code" />
    ...
</ContentPage>

В-третьих, изменить в Renderer на Android

using Xamarin.Forms.Platform.Android;

[assembly: ExportRenderer(typeof(MyEntry), typeof(MyEntryRenderer))]
namespace CustomRenderer.Android
{
    class MyEntryRenderer : EntryRenderer
    {
        public MyEntryRenderer(Context context) : base(context)
        {
        }

        protected override void OnElementChanged(ElementChangedEventArgs<Entry> e)
        {
            base.OnElementChanged(e);

            if (Control != null)
            {
                Control.InputType = Android.Text.InputTypes.Null;
                //Set input type be null, keyboard will never appear,even when click the Entry.If need show keyboard, this way also can be used.
                //Control.InputType = Android.Text.InputTypes.ClassText;
            }
        }
    }
}
