Change RecyclerView's Layout on orientation change

I'm having RecyclerView with GridLayoutManager. I'm displaying Single Column for landscape and Seven Columns for landscape. Using:

 @Override
    public void onConfigurationChanged(Configuration newConfig)
    {
        recyclerViewCalender.setLayoutManager(new GridLayoutManager(this, newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE ? 7 : 1));
        super.onConfigurationChanged(newConfig);
    }

But the problem is the Layout used for portrait is not feasible for landscape. So how can I change the layout of RecyclerView on configuration change. Or is there any other solution for it??

Here is the solution for this, Pass one Flag to you Adapter which describe current orientation.

@Override
public void onConfigurationChanged(Configuration newConfig)
{
    super.onConfigurationChanged(newConfig);
    //Update the Flag here
    orientationLand = (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE ? true : false);
}

In your Adapter class:

@Override
public CalenderSessionHolder onCreateViewHolder(ViewGroup parent, int viewType)
{
    //User Flag here to change layou
    View itemView = LayoutInflater.from(parent.getContext()).inflate(orientationLand ? R.layout.item_calender_session_land : R.layout.item_calender_session_port, null);
    return new CalenderSessionHolder(itemView);
}

Make sure you handle the View Id's properly to avoid Exceptions.

Update:

If you have two View Holder:

@Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
    {
        if (orientationLand)
        {
            View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_calender_session_land , parent, false);
            return new LandViewHolder(v);
        }
        else
        {
            View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_calender_session_port, parent, false);
            return new PortViewHolder(v);
        } 
        return null;
    }

In Bind ViewHolder

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position)
{
    if (holder instanceof PortViewHolder)
    {
        PortViewHolder portHolder = (PortViewHolder) holder;
        //Initialize Views here for Port View
    } else if (holder instanceof LandViewHolder)
    {
        LandViewHolder landViewHolder = (LandViewHolder) holder;
        //Initialize Views here for Land View
    }
}
