2 个微调器：从使用 Retrofit 选择的第一个微调器 ID 填充第二个微调器

Question

您好，我在使用我的 android，我有两个微调器并使用改装来填充我的微调器。我设法填充第一个微调器。但我不知道如何让我的第二个微调器填充在第一个微调器的 id selected 下。我正在使用 codeigniter rest controller 传递 id 并想使用第二个微调器的改造来检索它，但我不知道该怎么做？请帮助我。

我已经通过传递 id 创建了 Rest Controller。已经创建了 ApiInterface。和豆子来获取详细信息数据。第一个微调器工作正常。

声明

 classSpinner = (Spinner) findViewById(R.id.classSpinner);
    divSpinner = (Spinner) findViewById(R.id.divSpinner);

    classSpinner.setAdapter(mAdapter);

    mApiInterface = ApiClient.getClient().create(ApiInterface.class);

    getAllProvinsi();

Api接口

public interface ApiInterface {

//first spinner
    @GET("Testpage/provinsi")
    Call<GetProvinsi> getProvinsi();

//second spinner that I needed how to pass the id? and get data by id selected from first spinner
    @GET("Testpage/kotabyprovid/provinsi_id/")
    Call<GetKota> getKota();
}

GetProvinsi（第一个微调器）

public class GetProvinsi {

@SerializedName("result")
List<Provinsi> listDataProvinsi;


public List<Provinsi> getListDataProvinsi() {
    return listDataProvinsi;
}
public void setListDataProvinsi(List<Provinsi> listDataProvinsi) {
    this.listDataProvinsi = listDataProvinsi;
}

}

GetKota（第二个旋转器）

public class GetKota {

@SerializedName("result")
List<Kota> listDataKota;


public List<Kota> getListDataKota() {
    return listDataKota;
}
public void setListDataKota(List<Kota> listDataKota) {
    this.listDataKota = listDataKota;
}

}

第一个获取所有数据的微调器。我正在尝试 select id 从适配器填充第二个微调器。

private void getAllProvinsi() {

    Call<GetProvinsi> kontakCall = mApiInterface.getProvinsi();
    kontakCall.enqueue(new Callback<GetProvinsi>() {
        @Override
        public void onResponse(Call<GetProvinsi> call, Response<GetProvinsi>
                response) {
            List<Provinsi> ProvinsiList = response.body().getListDataProvinsi();
            Log.d("Retrofit Get", "Jumlah data Kontak: " +
                    String.valueOf(ProvinsiList.size()));
            //mAdapter = new KontakAdapter(KontakList, getBaseContext());

            mAdapter = new ProvinsiAdapter(ProvinsiList, getBaseContext(), new ProvinsiAdapter.DetailsAdapterListener() {
                @Override
                public void classOnClick(View v, int position) {
                    //showClass(mTrainDetails, position);// do something or navigate to detailed classes
                }

                @Override
                public void daysOnClick(View v, int position) {
                    //showDays(movieList, position);// do something or navigate to running days
                }
            });

            classSpinner.setAdapter(mAdapter);
            mAdapter.notifyDataSetChanged();
        }

        @Override
        public void onFailure(Call<GetProvinsi> call, Throwable t) {
            Log.e("Retrofit Get", t.toString());
        }
    });

第一个使用 OnItemSelectedListner 实现的 Spinner 适配器，我需要有关该方法的帮助？

public class ProvinsiAdapter extends BaseAdapter implements AdapterView.OnItemSelectedListener {
    private LayoutInflater inflater;
List<Provinsi> mProvinsiList;
public ProvinsiAdapter.DetailsAdapterListener onClickListener;

    public ProvinsiAdapter(List<Provinsi> provinsiList, Context context, ProvinsiAdapter.DetailsAdapterListener listener) {
        inflater = LayoutInflater.from(context);
        this.mProvinsiList = provinsiList;
        this.onClickListener = listener;
    }

    public int getCount() {
        // TODO Auto-generated method stub
        return mProvinsiList.size();
    }

    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        ViewHolder holder;

        if(convertView == null){
            convertView = inflater.inflate(R.layout.lsv_provinsi_list, null);
            holder = new ViewHolder();
            holder.txtMenuName = (TextView) convertView.findViewById(R.id.tv_namaProv);
            holder.txtQuantity = (TextView) convertView.findViewById(R.id.tv_idProv);


            convertView.setTag(holder);
        }else{
            holder = (ViewHolder) convertView.getTag();
        }


        holder.txtMenuName.setText(mProvinsiList.get(position).getNamaProvinsi());

            holder.txtQuantity.setText(String.valueOf(mProvinsiList.get(position).getId()));



        return convertView;
    }

@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

//Please help what should I put in here to populate second spinner

}

@Override
public void onNothingSelected(AdapterView<?> parent) {

}

static class ViewHolder {
        TextView txtMenuName, txtQuantity, txtPrice;
    }

//region Interface Details listener
public interface DetailsAdapterListener {

    void classOnClick(View v, int position);

    void daysOnClick(View v, int position);
}

}

JSON 第二个微调器 Testpage/kotabyprovid/provinsi_id/1 的结果

{"result":[{"id_kota":"17","provinsi_id":"1","nama_kota":"Badung"},{"id_kota":"32","provinsi_id":"1","nama_kota":"Bangli"},{"id_kota":"94","provinsi_id":"1","nama_kota":"Buleleng"},{"id_kota":"114","provinsi_id":"1","nama_kota":"Denpasar"},{"id_kota":"128","provinsi_id":"1","nama_kota":"Gianyar"},{"id_kota":"161","provinsi_id":"1","nama_kota":"Jembrana"},{"id_kota":"170","provinsi_id":"1","nama_kota":"Karangasem"},{"id_kota":"197","provinsi_id":"1","nama_kota":"Klungkung"},{"id_kota":"447","provinsi_id":"1","nama_kota":"Tabanan"}],"0":200}

请帮忙，谢谢

Answer 1

替换

@GET("Testpage/kotabyprovid/provinsi_id/")  
Call<GetKota> getKota();

和

@GET("Testpage/kotabyprovid/provinsi_id/{prov_id}")  
Call<GetKota> getKota(@Path("prov_id") int provId);

现在您可以将 id 传递给该方法，改造将负责将 provId 传递给 URL 路径。
