Try this way

try {
        activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {

                Rect r = new Rect();
                getScreenRootView().getWindowVisibleDisplayFrame(r);


                int heightDiff = activityRootView.getRootView().getHeight() - (r.bottom - r.top);
                if (heightDiff > 100) {
                    // keypad is open
                } 
            }
        });
    } catch (Throwable e) {
        e.printStackTrace();
    }
