How to capture the “virtual keyboard show/hide” event in Android?

Question

I would like to alter the layout based on whether the virtual keyboard is shown or not. I\'ve searched the API and various blogs but can\'t seem to find anything useful.

Answer 1

using viewTreeObserver for easily get the keyboard event.

layout_parent.viewTreeObserver.addOnGlobalLayoutListener {
            val r = Rect()
            layout_parent.getWindowVisibleDisplayFrame(r)
            if (layout_parent.rootView.height - (r.bottom - r.top) > 100) { // if more than 100 pixels, its probably a keyboard...
                Log.e("TAG:", "keyboard open")
            } else {
                Log.e("TAG:", "keyboard close")
            }
        }

** layout_parent is your view like edit_text.parent
