Question

Maui android screen keyboard for entry when keyboard is showing

Haviv Elbsz 2,071

Hello all. I use entry handler to prevent keyboard pop when the entry has focused and it works ok but if the keyboard is already showing and I tap the entry field the keyboard still showing and I need to manually hide it. How I can fix that programmatically. Thank you very much.

I tried to use hideSoftInputFromInputMethod to hide softkeyboard programmatically when specific entry get focus, but this method is deprecated, if I use InputMethodService#requestHideSelf(int) instead. This method was intended for IME developers, do you want to create custom keyboard completely for android platform?

Lu Thank you very much. Actually I tried to completely customize the keyboard but I don't know how to. I have already done one for one entry field with a grid hide show technic . If you can direct me to do a popup keyboard I'll appreciate your efforts and that will make me happy. Thank you.

Based on your screenshot, you create a custom keyboard, but android provide the same keyboard after your set <Entry Keyboard="Numeric"> , you do not need to create a new custom keyboard and hide the system keyboard.

I checked all the options provided by the options email, numeric,... no one has the characters I need. the characters I need are all digits and ! a b * = < > - and a space char. Thank you.

You can Migrate a custom renderer to a .NET MAUI handler to create a custom entry, then return following custom edittext to hide keyboard when OnCheckIsTextEditor and OnSelectionChanged event executed


    public sealed partial class CustomEditorHandler : ViewHandler<CustomEntryNoKeyboard, EditText>
    {
        protected override EditText CreatePlatformView()
        {
            return new NoKeyEditText(Context);
        }
        protected override void ConnectHandler(EditText platformView)
        {
            base.ConnectHandler(platformView);
        }


       static void MapIsKeyboardEnabled(CustomEditorHandler handler, CustomEntryNoKeyboard editor)
        {
        }
    }

#if ANDROID
    public class NoKeyEditText : EditText
    {
        Context context;
        public NoKeyEditText(Context context) : base(context)
        {
            this.context = context;
        }
        protected NoKeyEditText(nint javaReference, JniHandleOwnership transfer) : base(javaReference, transfer)
        {
        }



       public override bool OnCheckIsTextEditor()
        {
            HideKeyBoard();
            return base.OnCheckIsTextEditor();
        }


       private void HideKeyBoard()
        {
            InputMethodManager inputMethodManager = Microsoft.Maui.ApplicationModel.Platform.CurrentActivity.GetSystemService(Context.InputMethodService) as InputMethodManager;
            //   context.GetWindow()
            inputMethodManager.HideSoftInputFromWindow(this.WindowToken, HideSoftInputFlags.None);
        }


       protected override void OnSelectionChanged(int selStart, int selEnd)
        {
            HideKeyBoard();
            base.OnSelectionChanged(selStart, selEnd);
        }
    }


#endif
}

You are welcome. Yes, achieving this is more complicated. Because I tried to use EntryHandler and following code to hide it when Entry click event is executed. But it is not working at the first time click event. And it is working at next time click event, so we have to re-write Edittext for android platform. We need to hide the softkeyboard during initialization

InputMethodManager inputMethodManager = Microsoft.Maui.ApplicationModel.Platform.CurrentActivity.GetSystemService(Context.InputMethodService) as InputMethodManager; // context.GetWindow() inputMethodManager.HideSoftInputFromWindow(this.WindowToken, HideSoftInputFlags.None);
