android recycler中的适配器未附加错误

Question

我已经定义了单独的适配器类，获取器和设置器。

任何人都可以帮助清除错误吗？

谢谢。

这是使用回收者视图的类。单独的卡片视图已附加到回收站

public class boxInService extends AppCompatActivity {

    RecyclerView recyclerView;
    inserviceAdapter inadapter;
    List<serviceData> serviceDataList;
    ProgressDialog progressDialog;
    private SharedPreferences pref;
    private static final String PREF_NAME="share_pref";
    String op;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_box_in_service);
        getSupportActionBar().setTitle("Boxes in Service");
        serviceDataList=new ArrayList<>();
        recyclerView=findViewById(R.id.in_service_recycler);
        recyclerView.setHasFixedSize(true);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));

        pref=getSharedPreferences(PREF_NAME,MODE_PRIVATE);
        op=pref.getString("operator_stored","");
        progressDialog=new ProgressDialog(this);
        progressDialog.setMessage("Loading....");
        progressDialog.show();

        loadData();

    }

    private void loadData() {

        StringRequest request=new StringRequest(
                Request.Method.GET,
                ROOT_URL + boxinService + op,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {

                        progressDialog.dismiss();
                        try {
                            JSONArray jsonArray=new JSONArray(response);
                            for (int i=0;i<=jsonArray.length();i++){
                                JSONObject object=jsonArray.getJSONObject(i);
                                String chip=object.getString("chip_id");
                                String ua=object.getString("ua_key");
                                String cas=object.getString("cas");
                                String model=object.getString("stb_type");

                                serviceData s_Data=new serviceData(chip,ua,cas,model);
                                serviceDataList.add(s_Data);

                            }

                            inadapter=new inserviceAdapter(boxInService.this,serviceDataList);
                            recyclerView.setAdapter(inadapter);
                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                },
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        progressDialog.hide();
                        Toast.makeText(getApplicationContext(),error.getMessage(),Toast.LENGTH_SHORT).show();

                    }
                }
        );

        VolleyRequest.getInstance(this).addToRequest(request);
    }

}

有什么遗漏吗？
