问题
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)",
"textLower": "$38.78",
"packList": [
{
"textUpper": "3 DOSES",
"textLower": "$38.78",
}
{
"textUpper": "6 DOSES",
"textLower": "$71.60",
}
]
},
{
"textUpper": "Revolution for (Blue)",
"textLower": "$46.92",
"packList": [
{
"textUpper": "3 DOSES",
"textLower": "$46.92",
}
{
"textUpper": "6 DOSES",
"textLower": "$79.56",
}
{
"textUpper": "12 DOSES",
"textLower": "$137.27",
}
]
}
]
},
"Status": 1,
"Message": "",
"UserMessage": ""
}
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?

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();
}
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);
}
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());
