如何訪問arraylist在適配器

嗨，我正在android應用程序。我在我的應用程序中使用json解析。首先這是我的JSON響應如何訪問arraylist在適配器

{ 
    "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": "" 
}

現在我使用自定義警告對話框加載SizeList的陣列和另一個dailog爲packlist陣列。現在我想要的是，當用戶從sizelist中選擇（粉紅色），然後在第二個dailog中，我想要顯示來自packlist的3個劑量和6個劑量，並且當用戶選擇（藍色）時，我想顯示3個劑量，6個劑量，12個劑量。現在我只有最後兩項（藍色）6劑，12劑。任何人都可以幫我解決這個問題嗎？

你需要有packlist類型的數組列表中你SizeList的模式類的內部 –

是的，我已經 – chris

@VivekMishra你能幫 – chris

更改您的showDialogpacks像第一個對話框的this.On點擊傳球被點擊的位置，然後在裏面通過只有項目裏面sizelists特定的位置。

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(); 



}

還將第二個適配器列表類型更改爲ProductLandingPackListModel。

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

而在CustomAdapdtertwo getView方法

final ProductLandingPackListModel model = adaptersizelist.get(position); 

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

它給出的錯誤（getActivity（），sizelists.get（position））;這裏。在第二個適配器，我需要改變？ – chris

兄弟問題是在這裏第二個適配器得到count.You需要傳遞單個內部數組項目。通過sizelists.get（position）.packList。 – Anonymous

我duno你的方法名..你需要像那樣傳遞，也改變arrayList裏面的第二個適配器。它應該是List adaptersizelist – Anonymous

嗨克里斯基於尺寸的選擇集packlist ......各種規模用戶的更新包列表中選擇

好的告訴我該怎麼做？請檢查代碼。 – chris

你的第二個適配器應該是ArrayList類型，並且在點擊下面SizeList的showDialogPacks（ArrayList的 packList）設置一樣，將其設置爲recyclerview – Shanmugam

我想，太,,但其NT給予適當輸出 – chris
