Прокрутка RecylerView не работает на API 22

Я пытаюсь попробовать свое приложение на API 22, но оно работает на моем эмуляторе, но у меня проблема со списком прокрутки внутри RecylerView, я не вижу никаких ошибок на своем Logcat

Вот как я это установил

mAdapter = new Sales_detail_adapter(getActivity(),detailList);
        RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(v.getContext());
        recyclerView.setAdapter(mAdapter);
        recyclerView.setLayoutManager(mLayoutManager);
        recyclerView.setItemAnimator(new DefaultItemAnimator());

а вот onResponse

public void onResponse(String response) {
                        try {
                            JSONObject jsonObjd         = new JSONObject(response);
                            JSONArray arrayDetail       = jsonObjd.getJSONArray("Salesd");
                            for(int i = 0; i < arrayDetail.length();i++){
                                JSONObject detail = arrayDetail.getJSONObject(i);
                                Sales_detail_model sdn = new Sales_detail_model(
                                            detail.getString("IdHeader"),
                                            detail.getString("ItemCode"),
                                            detail.getString("HargaItem"),
                                            detail.getString("PromotionID"),
                                            "0",
                                            detail.getString("Quantity"),
                                            detail.getString("HargaSetelahPromosi"),
                                            detail.getString("TotalHarga"),
                                            detail.getString("NoNota"),
                                            detail.getInt("Status")
                                            );
                                            detailList.add(sdn);
                            }

                            mAdapter.notifyDataSetChanged();
                            mAdapter = new Sales_detail_adapter(getActivity(),detailList);
                            recyclerView.setAdapter(mAdapter);
                            progressDialog.hide();

                        } catch (JSONException e) {
                            progressDialog.hide();
                            e.printStackTrace();
                        }
                    }eue.add(postRequest);
    }
