Question

我在使用Okhttp中的list_state时遇到问题，当我尝试在适配器中传递它时，结果为空。我不明白，因为在onResponse内部使用的所有变量都不会传递到其外部。我试图在onResponse内设置一个recyclerview和适配器，但是在它上面出现了错误并导致ap崩溃。我使用的代码在下面有没有人可以帮助我？对不起，我的英语。

public class dashboard_device extends Fragment implements ListOwner{
    RecyclerView mRecicleView;
    RecyclerView.LayoutManager mLayoutManager;
    RecyclerView.Adapter mAdapter;
    ArrayList<String> lista_show;
    ArrayList<String> lista_state = new ArrayList<String> ();
    ArrayList<String> lista_prestate = new ArrayList<String> ();
    String p,d;
    String myResponse = null;
    List<risposta_json> posts;
    public dashboard_device() {
        // Required empty public constructor

    }


    @Override
    public View onCreateView(LayoutInflater inflater, final ViewGroup container,
                             Bundle savedInstanceState) {
        View fragmentView =  inflater.inflate (R.layout.dashboard_device_layout, container, false);
        final ArrayList<String> lista_show = new ArrayList<String> ();

        dashboard_DB db1 = new dashboard_DB (getContext ());
        //recupero datbase DB
        db1.open();
        Cursor c = db1.ottieniTuttidati();
        if (c.moveToFirst()) {
            do {
                lista_show.add (c.getString(2));
            } while (c.moveToNext());

        }
        db1.close();

        //fine recupero dati da db
        // Inflate the layout for this fragment



        GestioneDB db = new GestioneDB(getContext ());
        db.open();
        Cursor c1 = db.ottieniTuttidati();
        if (c1.moveToFirst()) {
            do {

                p =  c1.getString(1);
                d = c1.getString(2);

            } while (c1.moveToNext());
        }
        db.close();
        //fine recupero dati da db
        final String url = p;
        String token=d;

    }

    @Override
    public void push(ArrayList<String> list) {

    }

}

已解决 .getactivity（）。runOnUiThread（新的Runnable）等...等等...

Okhttp解析和recyclerview片段？
