Добавлен следующий код в Activity oncreate для устранения проблемы, перекрывающей панель инструментов Android с панелью состояния 

public void setWinowInsetsFramentContianer() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT_WATCH) {
        findViewById(R.id.main_content).setOnApplyWindowInsetsListener(new View.OnApplyWindowInsetsListener() {
            @Override
            public WindowInsets onApplyWindowInsets(View view, WindowInsets windowInsets) {
                ViewGroup viewGroup = (ViewGroup) view;
                boolean consumed = false;
                for (int i = 0; i < viewGroup.getChildCount(); i++) {
                    View child = viewGroup.getChildAt(i);
                    WindowInsets childResult = null;
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT_WATCH) {
                        childResult = child.dispatchApplyWindowInsets(windowInsets);
                    }
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                        if (childResult.isConsumed()) {
                            consumed = true;
                        }
                    }
                }
                if (consumed) {
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT_WATCH) {
                        return windowInsets.consumeSystemWindowInsets();
                    }
                } else {
                    return windowInsets;
                }
                return windowInsets;
            }

        });
    }
}

Мой RecyclerView исчезает при повторном просмотре фрагмента, если я удаляю android: fitsSystemWindows = "true " все работает нормально, это происходит после того, как я обновил библиотеку поддержки до 27.1.1 , до этого она работала нормально
