How do I detect if software keyboard is visible on Android Device or not?

Question

Is there a way in Android to detect if the software (a.k.a. \"soft\") keyboard is visible on screen?

Answer of @iWantScala is great but not working for me
rootView.getRootView().getHeight() always has the same value

one way is to define two vars

private int maxRootViewHeight = 0;
private int currentRootViewHeight = 0;

add global listener

rootView.getViewTreeObserver()
    .addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            currentRootViewHeight = rootView.getHeight();
            if (currentRootViewHeight > maxRootViewHeight) {
                maxRootViewHeight = currentRootViewHeight;
            }
        }
    });

then check

if (currentRootViewHeight >= maxRootViewHeight) {
    // Keyboard is hidden
} else {
    // Keyboard is shown
}

works fine
