SwipeRefreshLayoutは最後のRecyclerviewアイテムのみを正しく更新しています

Question

RecyclerviewのすべてのアイテムをSwipeRefreshlayout、 で更新しようとしていますが、残念ながら最後のアイテムのみが更新され、残りは変更されません。

はここに私の関連するコードです：

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    //LeakCanary.install(this.getApplication()); 

    setContentView(R.layout.activity_main); 
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { 
     Window window = getWindow(); 
     window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS); 
     window.setStatusBarColor(ContextCompat.getColor(this, R.color.colorPrimaryDark)); 
    } 

    handleArrayList(getApplicationContext(), 0); 
    Log.d("Arraylist", "" + intentNumber2.size()); 

    recyclerView = (RecyclerView) findViewById(R.id.rv); 
    LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this); 
    linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL); 
    recyclerView.setLayoutManager(linearLayoutManager); 
    recyclerView.setItemAnimator(null); 
    recyclerView.setHasFixedSize(true); 

    SimpleAdapter adapter = new SimpleAdapter(); 

    recyclerView.addItemDecoration(new SimpleDividerItemDecoration(this)); 
    recyclerView.setAdapter(adapter); 

    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); 
    fab.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      Intent intent = new Intent(getBaseContext(), AddReminder.class); 
      startActivity(intent); 
     } 
    }); 

    adapter.notifyItemInserted(cards.size() - 1); 

    refreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeRefreshLayout); 

    updateRemainingTime(); 

    refreshLayout.setOnRefreshListener(this); 
} 

@Override 
public void onRefresh() { 
    updateRemainingTime(); 
} 

//refresh the time remaining on the cards 
private void updateRemainingTime() { 

    if (!cards.isEmpty()) { 

     for (int i = cards.size()-1; i >= 0; i--) { 
      Card card = cards.get(i); 

      String time = card.getCardTime(); 
      String date = card.getCardDate(); 

      Date now = new Date(); 
      Date then = null; 
      try { 
       then = sdtf.parse(date + " " + time); 
      } catch (ParseException e) { 
       Log.d("PARSEEXCEPTION:", " " + e); 
      } 

      String remainingTime = calculate.calcTimeDiff(then.getTime(), now.getTime()); 
      Log.d("Card","Card updated " + remainingTime); 
      card.cardRemainingTime(remainingTime); 
      recyclerView.getAdapter().notifyItemChanged(i); 
     } 

     refreshLayout.setRefreshing(false); 
    } else { 
     refreshLayout.setRefreshing(false); 
    } 
} 

マイアダプタ：

public class SimpleAdapter extends RecyclerView.Adapter<SimpleAdapter.ViewHolder> implements RemoveItem { 

    @Override 
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     LayoutInflater inflater = LayoutInflater.from(parent.getContext()); 
     View itemView = inflater.inflate(R.layout.item_main, parent, false); 

     return new ViewHolder(itemView, this); 
    } 

    @Override 
    public void onBindViewHolder(ViewHolder holder, int position) { 
     Card card = cards.get(position); 
     holder.setReminderText(card.getCardText()); 
     card_tv2.setText(card.getCardRemainingTime()); 
     holder.setSelectable(true); 
    } 

    @Override 
    public int getItemCount() { 
     return cards.size(); 
    } 

    @Override 
    public void remove(int position) { 
     cards.remove(position); 
     Log.d("Main", "removed " + position); 
     notifyItemRemoved(position); 
     notifyItemRangeChanged(position, cards.size()); 

     AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE); 

     Intent intent1 = new Intent(getBaseContext(), AlarmReceiver.class); 

     int intentNumber = intentNumber2.get(position); 
     intentNumber2.remove(position); 
     Log.d("IntentNumber", "" + intentNumber); 

     PendingIntent alarmIntent = PendingIntent.getBroadcast(getApplicationContext(), intentNumber, intent1, PendingIntent.FLAG_CANCEL_CURRENT); 
     alarmIntent.cancel(); 

     alarmManager.cancel(alarmIntent); 

     File dir = getFilesDir(); 
     File file = new File(dir, "Reminder" + " " + position); 
     boolean deleted = file.delete(); 

     MainActivity.handleArrayList(getApplicationContext(), 1); 
    } 

    public class ViewHolder extends SwappingHolder implements View.OnClickListener, View.OnLongClickListener { 

     public final LinearLayout background; 

     public ViewHolder(View itemView, RemoveItem removeItem1) { 
      super(itemView, multiSelector); 
      itemView.setOnClickListener(this); 
      itemView.setOnLongClickListener(this); 
      itemView.setLongClickable(true); 
      removeItem = removeItem1; 

      card_tv = (TextView) itemView.findViewById(R.id.card_tv); 
      card_tv2 = (TextView) itemView.findViewById(R.id.card_tv2); 
      card_th = (ImageView) itemView.findViewById(R.id.thumbnail); 
      card_check = (ImageView) itemView.findViewById(R.id.card_check); 
      background = (LinearLayout) itemView.findViewById(R.id.background); 

     } 


     @Override 
     public void onClick(View view) { 
      if (multiSelector.tapSelection(this)) { 

       background.setSelected(true); 

      } else { 

       int position = getAdapterPosition(); 
       String text = "error"; 
       String time = "error"; 
       String date = "error"; 
       String repeat; 
       boolean repeat2 = false; 
       String quantity = "error"; 
       String mode = "error"; 

       try { 
        InputStream inputStream = openFileInput("Reminder" + " " + position); 
        InputStreamReader inputStreamReader = new InputStreamReader(inputStream); 
        BufferedReader bufferedReader = new BufferedReader(inputStreamReader); 
        text = bufferedReader.readLine(); 
        time = bufferedReader.readLine(); 
        date = bufferedReader.readLine(); 
        repeat = bufferedReader.readLine(); 
        repeat2 = repeat.equals("true"); 
        quantity = bufferedReader.readLine(); 
        mode = bufferedReader.readLine(); 
        inputStreamReader.close(); 
        bufferedReader.close(); 
        inputStream.close(); 
       } catch (Exception e) { 
        e.printStackTrace(); 
       } 

       Intent intent2 = new Intent(getBaseContext(), ChangeReminder.class); 
       intent2.putExtra("POSITION", position); 
       intent2.putExtra("TIME", time); 
       intent2.putExtra("DATE", date); 
       intent2.putExtra("TEXT", text); 
       intent2.putExtra("REPEAT", repeat2); 
       intent2.putExtra("QUANTITY", quantity); 
       intent2.putExtra("MODE", mode); 
       startActivity(intent2); 

      } 
     } 

     @Override 
     public boolean onLongClick(View view) { 
      AppCompatActivity activity = MainActivity.this; 
      activity.startSupportActionMode(mDeleteMode); 
      multiSelector.setSelectable(true); 
      multiSelector.setSelected(this, true); 
      background.setSelected(true); 
      return true; 
     } 

     public void setReminderText(String cardText) { 
      card_tv.setText(cardText); 

      ColorGenerator colorGenerator = ColorGenerator.MATERIAL; 
      TextDrawable drawableBuilder; 
      String letter = "A"; 

      if (cardText != null && !cardText.isEmpty()) { 
       letter = cardText.substring(0, 1); 
      } 

      int color = colorGenerator.getRandomColor(); 

      drawableBuilder = TextDrawable.builder() 
        .buildRound(letter, color); 
      card_th.setImageDrawable(drawableBuilder); 
      } 
     } 
     } 
    } 

カードのクラス：

public class Card implements Serializable { 
public int drawable; 
private String cardText; 
private String cardDate; 
private String cardTime; 
private String cardRemainingTime; 

public void cardText(String cardText) { 
    this.cardText = cardText; 
} 

public void cardDate(String cardDate) { 
    this.cardDate = cardDate; 
} 

public void cardTime(String cardTime) { 
    this.cardTime = cardTime; 
} 

public void cardRemainingTime(String cardRemainingTime) { 
    this.cardRemainingTime = cardRemainingTime; 
} 

public String getCardText() { 
    return cardText; 
} 

public String getCardDate() { 
    return cardDate; 
} 

public String getCardTime() { 
    return cardTime; 
} 

public String getCardRemainingTime() { 
    return cardRemainingTime; 
    } 
} 

編集：私は見つけた 私はアプリを再び開いたときに、すべてのアイテムが正しく更新されます。 これは、onRefreshとonCreateのupdateRemainingTimeを呼び出す間に違いがなければならないことを意味しますが、わかりません。どんな助けもありがとう。

Answer 1

updateRemainingTimeメソッドを変更します。
