私はこのjsonオブジェクトをsectionRecyclerViewに設定していますが、各セクションの特定のキーデータだけを取得していません。

そして、これは私が期待mは何出力されます：私は取得mは何

private void parseJson(JSONObject data) { 
     if (data != null) { 
      Iterator<String> it = data.keys(); 
      while (it.hasNext()) { 
       key = it.next(); 
       Log.d("Key:", key); 
       Document document = new Document(); 
       document.setDate(key); 
       try { 
        if (data.get(key) instanceof JSONArray) { 
         JSONArray arry = data.getJSONArray(key); 
         int size = arry.length(); 
         for (int i = 0; i < size; i++) { 
          DocumentFiles files = new DocumentFiles(); 
          JSONObject obj = arry.getJSONObject(i); 
          files.setFileName(obj.getString("description")); 
          mDocumentFiles.add(files); 
          document.setmList(mDocumentFiles); 
          Log.d("Description:",obj.getString("description")); 
         } 

         Log.d("Stop:", "Yes"); 
         mDocumentList.add(document); 
         adapterDocument.addSection(new MySection(key, mDocumentList, mDocumentFiles)); 
        } else if (data.get(key) instanceof JSONObject) { 

        } else { 
         System.out.println("" + key + " : " + data.optString(key)); 
        } 
       } catch (Throwable e) { 
        System.out.println("" + key + " : " + data.optString(key)); 
        e.printStackTrace(); 
       } 
      } 
     } 
     adapterDocument.notifyDataSetChanged(); 
    } 

ViewHolderクラス

public class MySection extends StatelessSection { 

    String date; 
    List<Document> documentList; 
    List<DocumentFiles> documentFileList; 


    public MySection(String date, List<Document> callList, List<DocumentFiles> documentFileList) { 
     // call constructor with layout resources for this Section header, footer and items 
     super(new SectionParameters.Builder(R.layout.section_item) 
       .headerResourceId(R.layout.section_header) 
       .build()); 
     this.date = date; 
     this.documentList = callList; 
     this.documentFileList = documentFileList; 
    } 

    @Override 
    public int getContentItemsTotal() { 
     return documentList.size(); // number of items of this section 
    } 

    @Override 
    public RecyclerView.ViewHolder getItemViewHolder(View view) { 
     // return a custom instance of ViewHolder for the items of this section 
     return new MyItemViewHolder(view); 
    } 

    @Override 
    public void onBindItemViewHolder(RecyclerView.ViewHolder holder, int position) { 
     MyItemViewHolder itemHolder = (MyItemViewHolder) holder; 
     DocumentFiles files = documentFileList.get(position); 
     itemHolder.txtFile.setText(files.getFileName()); 

     // itemHolder.txtFile.setText(documentList.get(position).getFileName()); 
    } 

    @Override 
    public RecyclerView.ViewHolder getHeaderViewHolder(View view) { 
     return new MyHeaderViewHolder(view); 
    } 

    @Override 
    public void onBindHeaderViewHolder(RecyclerView.ViewHolder holder) { 
     MyHeaderViewHolder headerHolder = (MyHeaderViewHolder) holder; 
     headerHolder.txtDate.setText(date); 
    } 

    class MyItemViewHolder extends RecyclerView.ViewHolder { 
     private final TextView txtFile; 

     public MyItemViewHolder(View itemView) { 
      super(itemView); 
      txtFile = (TextView) itemView.findViewById(R.id.txtFname); 
     } 
    } 

    class MyHeaderViewHolder extends RecyclerView.ViewHolder { 
     private final TextView txtDate; 

     public MyHeaderViewHolder(View itemView) { 
      super(itemView); 
      txtDate = (TextView) itemView.findViewById(R.id.txtDate); 
     } 
    } 
} 

出力がある

どのように私はちょうど各ヘッダーセクションにperticularイベントを設定しますか？、助けてください..ありがとう

Answer 1

問題は、List<DocumentFiles>を作成し、すべてのアイテムが完全なリストオブジェクトを取るようにすべてのアイテムへの参照を与えています。

すべてのドキュメントに対してList<DocumentFiles>を作成し、正常に動作する各ドキュメントに設定してください。

private void parseJson(JSONObject data) { 
    if (data != null) { 
     Iterator<String> it = data.keys(); 
     while (it.hasNext()) { 
      key = it.next(); 
      Log.d("Key:", key); 
      Document document = new Document(); 
      mDocumentFiles = new ArrayList<DocumentFiles>(); // create everytime new list for each header 
      document.setDate(key); 
      try { 
       if (data.get(key) instanceof JSONArray) { 
        JSONArray arry = data.getJSONArray(key); 
        int size = arry.length(); 
        for (int i = 0; i < size; i++) { 
         DocumentFiles files = new DocumentFiles(); 
         JSONObject obj = arry.getJSONObject(i); 
         files.setFileName(obj.getString("description")); 
         mDocumentFiles.add(files); 
         //document.setmList(mDocumentFiles); moved out of the loop 
         Log.d("Description:",obj.getString("description")); 
        } 

        Log.d("Stop:", "Yes"); 
        document.setmList(mDocumentFiles); 
        mDocumentList.add(document); 
        // No use of mDocumentList, you are using only mDocumentFiles 
        adapterDocument.addSection(new MySection(key, mDocumentList, mDocumentFiles)); 
       } else if (data.get(key) instanceof JSONObject) { 

       } else { 
        System.out.println("" + key + " : " + data.optString(key)); 
       } 
      } catch (Throwable e) { 
       System.out.println("" + key + " : " + data.optString(key)); 
       e.printStackTrace(); 
      } 
     } 
    } 
    adapterDocument.notifyDataSetChanged(); 
} 

そして、あなたのアダプタのサイズはdocumentFileListサイズ

@Override 
public int getContentItemsTotal() { 
    return documentFileList.size(); // number of documentFileList items of this section 
} 

Answer 2

する必要がありますあなたは、このメソッドを使用してデータを解析することができ、これはあなた

Map<String, List<DocumentChild>> parseData = parseJson(data); 
for (Map.Entry<String, List<DocumentChild>> entry : parseData.entrySet()) { 
    Log.d(TAG, entry.getKey() + "/" + entry.getValue()); 
} 

は日付によってあなたのJSONデータおよびグループの解析に役立つことを願っていますParseJsonを使用して

private Map<String, List<DocumentChild>> parseJson(String data) { 
    Map<String, List<DocumentChild>> dataMap = new HashMap<>(); 
    try { 
     JSONObject jsonObj = new JSONObject(data); 
     JSONObject jsonObject = jsonObj.getJSONObject("data"); 
     Iterator<String> it = jsonObject.keys(); 
     while (it.hasNext()) { 
      String strKey = it.next(); 
      JSONArray jsonArrayDate = jsonObject.getJSONArray(strKey); 
      for (int i = 0; i < jsonArrayDate.length(); i++) { 
       JSONObject jsonObjectData = jsonArrayDate.getJSONObject(i); 
       DocumentChild documentChild = new DocumentChild(); 
       documentChild.setId(jsonObjectData.getString("id")); 
       documentChild.setDescription(jsonObjectData.getString("description")); 
       documentChild.setFile(jsonObjectData.getString("file")); 
       documentChild.setCategoryName(jsonObjectData.getString("categoryname")); 
       documentChild.setCategoryId(jsonObjectData.getString("category_id")); 
       documentChild.setCreatedDate(jsonObjectData.getString("created")); 

       if (dataMap.containsKey(strKey)) { 
        // The key is already in the HashMap; add the pojo object 
        // against the existing key. 
        dataMap.get(strKey).add(documentChild); 
       } else { 
        List list = new ArrayList(); 
        list.add(documentChild); 
        dataMap.put(strKey, list); 
       } 
      } 
     } 
    } catch (JSONException e) { 
     Log.d(TAG, "Exception catched: " + e); 
     e.printStackTrace(); 
    } 

    return dataMap; 
} 

DocumentChild

public class DocumentChild { 
    private String id; 
    private String description; 
    private String file; 
    private String categoryName; 
    private String categoryId; 
    private String createdDate; 

    //TODO generate getter setter 

}
