我正在制作android应用程序.我在应用程序中使用json解析.首先，这是我的json响应

Hi i am making android application. I am using json parsing in my application. first of all this is my json response

{
  "Data": {
    "headerText": "Revolution",
    "productStartingPrice": "$38.78",

    "sizeList": [
      {
        "textUpper": "Revolution for (Pink)",

现在，我正在使用自定义警报对话框来加载size​​list数组和另一个Dailist Packlist数组.现在我想要的是当用户从尺寸列表中选择(粉红色)时，然后在第二个目录中，我想从包装列表中显示3剂和6剂；当用户选择(蓝色)时，我想要显示3剂，6剂，12剂.现在我只得到(Blue)6剂，12剂的最后两项.谁能帮我解决这个问题?

Now I am using custom alert dialog to load sizelist array and another dailog for packlist array. Now what i want is when user select (Pink) from sizelist then in second dailog i want to display 3 doses and 6 doses from packlist and when user select (Blue) i want to display 3 doses, 6 doses ,12 doses. Right now i am getting only last two items of (Blue) 6 doses ,12 doses. can any one help me to solve this?

推荐答案

像这样更改showDialogpacks.在单击第一个对话框时，传递被单击的位置，然后在其中仅传递项目 特定位置的内部尺码表.

Change your showDialogpacks like this.On click of the first dialog pass the position that is been clicked and then inside that pass only the item inside sizelists for particular position.

  private void showDialogpacks(int position){

    dialogfpacks = new Dialog(getActivity());

    View view = getActivity().getLayoutInflater().inflate(R.layout.dialog_main_packs, null);
    ListView lv = (ListView) view.findViewById(R.id.custom_list_packs);
    Button close_btn = (Button) view.findViewById(R.id.close_btn_packlist);

    adapterpacks = new CustomListAdaptertwo(getActivity(), sizelists.get(position).getPacklistmodel());
    lv.setAdapter(adapterpacks);

    lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

        }
    });

    dialogfpacks.setContentView(view);
    dialogfpacks.show();



}

还将第二个适配器列表类型更改为ProductLandingPackListModel.

Also change the second adapter list type to ProductLandingPackListModel.

  public CustomListAdaptertwo(Context context,List<ProductLandingPackListModel> adaptersizelist) {
        this.context = context;
        this.adaptersizelist=adaptersizelist;
        inflater = LayoutInflater.from(context);
    }

在CustomAdapdtertwo getView方法的内部

And in the inside of the CustomAdapdtertwo getView method

    final ProductLandingPackListModel model = adaptersizelist.get(position);

    holder.txtproname.setText(model.getPackList_textUpper());
    holder.txtproprice.setText(model.getPackList_textLower());
