RecyclerView with start offset

Question

I want that my first element in recycler view have offset by start list.

I try use

void onCreate(Bundle savedInstanceState){
...
    linearLayoutManager.scrollToPositionWithOffset
...
}

But it not work. I undestand that i can use empty view how zero element in list, but it not perfect solution.

They is two solution 1) Just use two type of views 2) add paddingTop to your recyclerview, and add clipToPadding false. — JCDecary, Aug 02 '16 at 13:06

First solution:

public class Adapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    public static final int VIEW_HEADER = 1, VIEW_INFO = 2;
    private Context context;

    public Adapter(Context context) {
        this.context = context;
    }

    @Override
    public int getItemViewType(int position) {
        if(position == 0) return VIEW_HEADER;
        return VIEW_INFO;
    }

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        switch (viewType){
            case VIEW_HEADER:
                return new HeaderViewHolder(LayoutInflater.from(context).inflate(your view));
            case VIEW_INFO:
                return new InfoViewHolder(LayoutInflater.from(context).inflate(your view));
        }
        return null;
    }

    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
        if(holder instanceof HeaderViewHolder){

        }else if (holder instanceof InfoViewHolder){

        }
    }

    @Override
    public int getItemCount() {
        return your items count + 1; // add the header
    }

    public static class HeaderViewHolder extends RecyclerView.ViewHolder{

        public HeaderViewHolder(View itemView) {
            super(itemView);
        }
    }

    public static class InfoViewHolder extends RecyclerView.ViewHolder{

        public InfoViewHolder(View itemView) {
            super(itemView);
        }
    }
}

second solution:add paddingTop to your recyclerview, and add clipToPadding false.

<androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingTop="100dp"
        android:clipToPadding="false"/>

I wonder why you tucked away the second solution, it was a really fast solution for me. — SEG.Veenstra, Jun 17 '20 at 09:32

I found a solution and it works great. First you need to get your recyclerviews last offset value by;

int offset = recyclerView.computeVerticalScrollOffset();

Or you can assign your offset value. Then after you set your adapter, you can set your offset like below.

recyclerView.setAdapter(Adapter.this);
LinearLayoutManager llm = (LinearLayoutManager) 
recyclerView.getLayoutManager();
llm.scrollToPositionWithOffset(0,-1*offset);

Its mean; llm scrolling position to 0(start) and then goes down to offset. I hope it helps!
