How to clear animation of adding/removing actionbar?

Question

At my application I am using container where I change several fragments. At some fragments I have to hide actionbar at parent activity. I managed to do it, but the process of hiding and viewing toolbar is supported with weird and uncomfortable animation. I hide and show toolbar via:

Objects.requireNonNull(getSupportActionBar()).hide();

Maybe I can clear animation?

I managed to find a solution for my problem with this method:

public static void disableShowHideAnimation(ActionBar actionBar) {
    try
    {
        actionBar.getClass().getDeclaredMethod("setShowHideAnimationEnabled", boolean.class).invoke(actionBar, false);
    }
    catch (Exception exception)
    {
        try {
            Field mActionBarField = actionBar.getClass().getSuperclass().getDeclaredField("mActionBar");
            mActionBarField.setAccessible(true);
            Object icsActionBar = mActionBarField.get(actionBar);
            Field mShowHideAnimationEnabledField = icsActionBar.getClass().getDeclaredField("mShowHideAnimationEnabled");
            mShowHideAnimationEnabledField.setAccessible(true);
            mShowHideAnimationEnabledField.set(icsActionBar,false);
            Field mCurrentShowAnimField = icsActionBar.getClass().getDeclaredField("mCurrentShowAnim");
            mCurrentShowAnimField.setAccessible(true);
            mCurrentShowAnimField.set(icsActionBar,null);
        }catch (Exception e){
            //....
        }
    }
}
