How to Hide/Close SoftKeyboard in Xamarin Android? - c

Question

In my program there is a standard keyboard that I use for the "Entry"
However I'm testing some things and I ended up putting IsEnabled = True, but when the program goes into Focus on that Entry, the default Android Softkeyboard appears, and I do not want it to appear when I click on Entry.
How do I not display the SoftKeyboard in Entry?

Answer 1

Customizing an Entry in Native android can do this:
First, creating a MyEntry
public class MyEntry : Entry
{
}
Second ,using in Xaml:
<ContentPage ...
xmlns:local="clr-namespace:CustomRenderer;assembly=CustomRenderer"
...>
...
<local:MyEntry Text="In Shared Code" />
...
</ContentPage>
Third, modify in Renderer on 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;
}
}
}
}
