Question

我正在调用以下方法在我的Android应用中填充recyclerview：

private void getDirectoriosFromDB(int id) {

        AsyncTask<Integer, Void, Void> asyncTask = new AsyncTask<Integer, Void, Void>() {
            @Override
            protected Void doInBackground(Integer... addressesIds) {
              //  Log.d("HOLA PERFIL", "UID REGISTRADO ANTES DE CARGAR REECYCLER: " + user_id);



                OkHttpClient client = new OkHttpClient();
                Request request = new Request.Builder()
                        .url("http://...directorio_todos.php")
                        .build();
                try {
                    okhttp3.Response response = client.newCall(request).execute();

                    JSONArray array = new JSONArray(response.body().string());

                    for (int i = 0; i < array.length(); i++) {

                        JSONObject object = array.getJSONObject(i);
                        Log.d("HOLA ADDRESSES", "DIRECCION LEIDA: " + i);
                        Directorio directorio = new Directorio(object.getInt("id_directorio"),
                                object.getString("nombre"),
                                object.getString("apellidos"),
                                object.getString("apodo"),
                                object.getString("cumple"),
                                object.getString("conyuge"),
                                object.getString("cumple_conyuge"),
                                object.getString("aniversario_bodas"),
                                object.getString("empresa"),
                                object.getString("direccion_empresa"),
                                object.getString("tel_negocio"),
                                object.getString("fecha_ingreso"),
                                object.getString("num_rotario"),
                                object.getString("padrino"),
                                object.getString("direccion_casa"),
                                object.getString("tel_casa"),
                                object.getString("celular"),
                                object.getString("email"),
                                object.getString("clasificacion"),
                                object.getString("imagen")
                                );

                        directorios.add(directorio);
                    }


                } catch (IOException e) {
                    e.printStackTrace();
                } catch (JSONException e) {
                    e.printStackTrace();
                }
                return null;
            }

            @Override
            protected void onPostExecute(Void aVoid) {
                adapter.notifyDataSetChanged();
            }
        };

        asyncTask.execute(id);
    }

现在我已经包含了一个搜索功能来过滤数据。

一旦用户输入搜索字符串，我希望recyclerview仅显示已过滤的项目，但它不起作用，recyclelerview不会更改其内容。

如何使用新内容重新制作Recyclerview？

如果您已成功实施搜索，请执行以下操作，

SessionFactory sessionFactory = HibernateUtil.getSessionFactory();
Session session = sessionFactory.openSession();
Transaction transaction = null;
try {
    transaction = session.beginTransaction();
    ***SOME UNIQUE OBJECT***  = (***SOME UNIQUE OBJECT TYPE***) session.save(***SOME UNIQUE OBJECT***);
    session.getTransaction().commit();
} catch (HibernateException e) {
    if (transaction != null) {
        transaction.rollback();
    }
} finally {
    session.close();
}
return ***SOME UNIQUE OBJECT***;

注意：我认为即使在搜索完成后，适配器中的集合内容也没有变化，// Update your adapter collection with the filtered data. adapter.notifyDataSetChanged();将在初始状态下使用相同的集合执行它的工作。

在Android中重复使用recyclerview
