RecyclerView scrollbar jumps back to top after first item

I created a very basic RecyclerView example.






public class MyActivity extends Activity {

    RecyclerView mRecyclerView;

    protected void onCreate(Bundle savedInstanceState) {

        mRecyclerView = (RecyclerView)
        mRecyclerView.setAdapter(new TestAdapter());
        mRecyclerView.setLayoutManager(new LinearLayoutManager(this));

    public static class TestAdapter extends
RecyclerView.Adapter<TestAdapter.ViewHolder> {
        public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int
i) {
            View view =
viewGroup, false);
            return new ViewHolder(view);

        public void onBindViewHolder(ViewHolder viewHolder, int i) {
  "Row " + (i + 1));

        public int getItemCount() {
            return 30;

        public static class ViewHolder extends RecyclerView.ViewHolder

            TextView tv;

            public ViewHolder(View itemView) {
                tv = (TextView)

Now when I scroll beyond the first item, the scrollbar jumps back to the top and then continues normally. The second problem is when I scroll to the bottom, the scrollbar stops to early. Is this a bug in the support lib or my own fault?
