android - 数据未显示在布局中

Question

我正在尝试从 API 获取数据，但数据似乎没有显示在我的布局中。没有错误，logcat 似乎指向第 58 行和第 54 行，但我不知道这些行有什么问题。

这是代码：

@SuppressLint("Registered")
public class WaktuAzan extends AppCompatActivity {

    private static final String URL_ANNOUNCEMENT = "http://interxsgroup.com.my:8887/waktu_solat/api.php?zon=SGR01";
    private RecyclerView recyclerViewAzan;
    private List<WaktuAzanList> waktuAzanLists;
    private RequestQueue mQueue;
    private WaktuAzanAdapter adapter;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.azan_layout);

        waktuAzanLists = new ArrayList<>();

        recyclerViewAzan = findViewById(R.id.recyclerViewAzan);
        recyclerViewAzan.setHasFixedSize(true);
        recyclerViewAzan.setLayoutManager(new LinearLayoutManager(this));


        mQueue = Volley.newRequestQueue(this);

        getAzan();
    }

    private void getAzan() {


line 54   StringRequest stringRequest = new StringRequest(Request.Method.GET, URL_ANNOUNCEMENT, new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                try {
line 58                JSONArray jsonArray = new JSONArray(response);


                    for (int i = 0; i < jsonArray.length(); i++) {
                        JSONObject data = jsonArray.getJSONObject(i);

                        waktuAzanLists.add(new WaktuAzanList(

//                                data.getString("waktu_imsak"),
//                                data.getString("waktu_subuh"),
//                                data.getString("waktu_syuruk"),
//                                data.getString("waktu_zohor"),
//                                data.getString("waktu_asar"),
//                                data.getString("waktu_maghrib"),
//                                data.getString("waktu_isyak"),
                                data.getString("nama_zon"),
                                data.getString("tarikh_masa")


                        ));

                        adapter = new WaktuAzanAdapter(waktuAzanLists,WaktuAzan.this);
                        recyclerViewAzan.setAdapter(adapter);
                    }
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                error.printStackTrace();
            }
        });

        mQueue.add(stringRequest);
    }
}

这是 logcat，log cat 似乎指向第 58 和 54 行。
