How to check visibility of software keyboard in Android?

Question

I need to do a very simple thing - find out if the software keyboard is shown. Is this possible in Android?

It has been forever in terms of computer but this question is still unbelievably relevant!

So I've taken the above answers and have combined and refined them a bit...

public interface OnKeyboardVisibilityListener {


    void onVisibilityChanged(boolean visible);
}

public final void setKeyboardListener(final OnKeyboardVisibilityListener listener) {
    final View activityRootView = ((ViewGroup) getActivity().findViewById(android.R.id.content)).getChildAt(0);

    activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

        private boolean wasOpened;

        private final int DefaultKeyboardDP = 100;

        // From @nathanielwolf answer...  Lollipop includes button bar in the root. Add height of button bar (48dp) to maxDiff
        private final int EstimatedKeyboardDP = DefaultKeyboardDP + (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP ? 48 : 0);

        private final Rect r = new Rect();

        @Override
        public void onGlobalLayout() {
            // Convert the dp to pixels.
            int estimatedKeyboardHeight = (int) TypedValue
                    .applyDimension(TypedValue.COMPLEX_UNIT_DIP, EstimatedKeyboardDP, activityRootView.getResources().getDisplayMetrics());

            // Conclude whether the keyboard is shown or not.
            activityRootView.getWindowVisibleDisplayFrame(r);
            int heightDiff = activityRootView.getRootView().getHeight() - (r.bottom - r.top);
            boolean isShown = heightDiff >= estimatedKeyboardHeight;

            if (isShown == wasOpened) {
                Log.d("Keyboard state", "Ignoring global layout change...");
                return;
            }

            wasOpened = isShown;
            listener.onVisibilityChanged(isShown);
        }
    });
}

Works for me :)

NOTE: If you notice that the DefaultKeyboardDP does not fit your device play with the value and post a comment for everyone to know what should be the value... eventually we will get the correct value to fit all devices!
