java.lang.IndexOutOfBoundsException：インデックス：7、サイズ：リフレッシュ後のサイズ：7

Question

すべてが正常に動作し、リフレッシュされます。更新後に新しいレコードがクリックされると、アプリケーションがクラッシュします。私asynctaskクラスの私のメインクラス

mPullToRefreshView = (PullToRefreshView)view.findViewById(R.id.pull_to_refresh); 
     mPullToRefreshView.setOnRefreshListener(new PullToRefreshView.OnRefreshListener() { 
      @Override 
      public void onRefresh() { 
       mPullToRefreshView.postDelayed(new Runnable() { 
        @Override 
        public void run() { 
         new RetrieveWarehouseSalesTask(getActivity()).execute(); 
        } 
       }, 10); 
      } 
     }); 

で

class RetrieveWarehouseSalesTask extends AsyncTask<Void,Void,Void> { 
    private String TAG = RetrieveWarehouseSalesTask.class.getSimpleName(); 
    private String TAG_PID = "pid"; 
    public ProgressDialog pDialog; 
    private Context context; 
    //URL to get JSON details 
    private String url = "http://localhost/abc.php"; 
    ArrayList<HashMap<String,String>> sales_details; 
    JSONObject jsonObj; 
    String jsonStr; 
    JSONArray sales; 

    //for recycler view 
    private RecyclerView warehouse_recycler; 
    private AdapterRecycler mAdapter; 
    List<WarehouseSalesDetails> data = new ArrayList<>(); 

    public RetrieveWarehouseSalesTask(Context context){ 
     this.context = context; 
     sales_details = new ArrayList<>(); 

    } 



    @Override 
    protected void onPreExecute(){ 
     super.onPreExecute(); 
     pDialog = new ProgressDialog(context); 
     pDialog.setMessage("Getting you the best warehouse sales..."); 
     pDialog.setCancelable(false); 
     pDialog.show(); 
    } 

    @Override 
    protected Void doInBackground(Void... arg0){ 
     HttpHandler sh = new HttpHandler(); 
     //making a request to URL and getting response 
     jsonStr = sh.makeServiceCall(url); 
     Log.e(TAG, "Response from url: " + jsonStr); 


     return null; 
    } 

    @Override 
    protected void onPostExecute(Void result){ 
     super.onPostExecute(result); 
     if(pDialog.isShowing()){ 
      pDialog.dismiss(); 
     } 
     if(jsonStr != null){ 
      try{ 
       jsonObj = new JSONObject(jsonStr); 
       //Getting JSON Array Node 
       sales = jsonObj.getJSONArray("Result"); 
       //looping through all results 
       for(int i = 0; i<sales.length();i++){ 
        JSONObject s = sales.getJSONObject(i); 
        WarehouseSalesDetails wsd = new WarehouseSalesDetails(); 
        wsd.expiry_date = s.getString("expiry_date"); 
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd"); 
        Date actual_date = sdf.parse(wsd.expiry_date); 
        if(new Date().before(actual_date)){ 
         wsd.id = s.getString("id"); 
         wsd.company_name = s.getString("company_name"); 
         wsd.promotion_image= s.getString("promotion_image"); 
         wsd.title = s.getString("title"); 
         wsd.promotional_period = s.getString("promotional_period"); 
         wsd.viewCount = s.getString("view_count"); 
         data.add(wsd); 
        } 
       } 
       Log.d("TAG",sales_details.toString()); 
      }catch(final JSONException e){ 
       Log.e(TAG, "JSON parsing error: " + e.getMessage()); 
      } catch (ParseException e) { 
       e.printStackTrace(); 
      } 
     }else{ 
      Log.e(TAG,"Couldn't get json from server"); 
     } 
     //update RecyclerView 
     warehouse_recycler = (RecyclerView)((AppCompatActivity) context).findViewById(R.id.recyclerView); 
     mAdapter = new AdapterRecycler(context, data); 
     final LinearLayoutManager layoutManager = new LinearLayoutManager(context); 
     layoutManager.setOrientation(LinearLayoutManager.VERTICAL); 
     warehouse_recycler.setLayoutManager(layoutManager); 
     warehouse_recycler.setAdapter(mAdapter); 
     warehouse_recycler.addOnItemTouchListener(
       new RecyclerItemClickListener(context,warehouse_recycler,new RecyclerItemClickListener.OnItemClickListener() { 
        @Override 
        public void onItemClick(View view, int position) { 
         WarehouseSalesDetails wsd = data.get(position); 
         // Toast.makeText(context,"ID is " + wsd.id, 
           //Toast.LENGTH_SHORT).show(); 
         String pid = wsd.id; 
         Intent in = new Intent(context,RetrieveIndividualWarehouseSales.class); 
         in.putExtra("pid",pid); 
         startActivity(in); 
        } 
        @Override 
        public void onLongItemClick(View view, int position){ 
         //do whatever 
        } 
       })); 
     mPullToRefreshView.setRefreshing(false); 
    } 

} 

Logcatポイントの行にエラー

WarehouseSalesDetails wsd = data.get(position); 

Logcatメッセージ

java.lang.IndexOutOfBoundsException: Index: 7, Size: 7 
                        at java.util.ArrayList.get(ArrayList.java:411) 

更新された後、最新のレコードを格納できないarraylistによる可能性があります。この問題についてどうすればいいですか？

Answer 1

これは、位置にアダプタクラスでのonClick方法自体

itemView.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        WarehouseSalesDetails wsd = data.get(getAdapterPosition()); 
        String pid = wsd.id; 
        Intent in = new Intent(context,RetrieveIndividualWarehouseSales.class); 
        in.putExtra("pid",pid); 
        context.startActivity(in); 
       } 
      });
