Close Keyboard on android

[Pierre]

Hi, how I can hide the overlay keyboard from appearing after set the focus oin the NumericInput.

For now I try with Depedency on cross platform without success

RadNumericInput ntb = Qte as RadNumericInput;
if (ntb != null)
{
    ntb.Focus();
    var key = Xamarin.Forms.DependencyService.Get<IForceKeyboardDismissalService>();
    key.DismissKeyboard();
}

 

then on droid:

[assembly: Xamarin.Forms.Dependency(typeof(AndroidForceKeyboardDismissalService))]
namespace KelvinMobile.Droid
{
    public class AndroidForceKeyboardDismissalService : IForceKeyboardDismissalService
    {
        public void DismissKeyboard()
        {
            InputMethodManager imm = InputMethodManager.FromContext(CrossCurrentActivity.Current.Activity.ApplicationContext);

            imm.HideSoftInputFromWindow(CrossCurrentActivity.Current.Activity.Window.DecorView.WindowToken, HideSoftInputFlags.NotAlways);
        }
    }
}

 

The call work, but the keyboard still there...

Hi Pierre,

You would need to get the RadEntry used inside the NumericInput control and create a custom renderer on Android for it where you could hide the keyboard.

I've created a sample project to show you how exactly this would work.  First, in order to get the entry, you would need to modify the ControlTemplate of the NumericInput. 
Inside the ControlTemplate replaced the NumericInputEntry with a custom one which type is used to export a renderer on Android.

Inside the renderer you could handle GotFocus event and hide the keyboard in it.  In addition, our Entry has some specifics related to styling its border, that's why creating a new natice control is needed.

Please download the attached file and give it a try. Let me know if any additional questions arise.

Great! Your sample work great and I convert it into my solution. Thanks a lot. Can you prodie me the custum renderer and/or MyNativeControl.cs for IOS and UWP? We plan to expend this program to IOS and windows soon. Thanks

Hi Pierre,

I am afraid I couldn't find a straightforward way to implement this on iOS (the internal implementation is different on each platform) , so I have logged a feature request on your behalf, you could cast your vote and track its status at the link below:

As to UWP - generally, I do not think such a feature would be applicable, still, we will have it in mind as well.

Let me know if I can help with anything else.
