How to close keyboard in Android ?

Question

In MAUI I am using this code to close android keyboard because every time user has to click on done from keyboard to close keyboard. I wanted a behaviour where if user click on anywhere in screen so it should close the keyboard. This behaviour is by default in IOS. For Android I've implemented this code.

But this method hits every time when user click on screen, I want to put validation here, if keyboard is already closed this method should not execute, Could you please help me in this?

        public void HideKeyboard()
        {

            InputMethodManager imm = InputMethodManager.FromContext(Microsoft.Maui.ApplicationModel.Platform.CurrentActivity.ApplicationContext);

            imm.HideSoftInputFromWindow(
                Microsoft.Maui.ApplicationModel.Platform.CurrentActivity.Window.DecorView.WindowToken, HideSoftInputFlags.NotAlways);
        }
