RecyclerView操作只能編輯第一個位置上的工作？

Question

因此，在我的recyclerview項目中，我允許用戶在eddittext和textview之間切換。它可以在回收站視圖的第一個位置完全處理項目，在第二個位置它只會切換編輯文本但不切換回文本視圖。然而，刪除選項適用於所有職位。這是我的recyclerview加墨機

我不得不改變我的看法是這樣的。我正在重新分配NoteItemHolder，認爲最終的變量不能被操縱。簡單地使用最終的變量使其工作。

@Override 
    public void onBindViewHolder(final NoteItemHolder holder, int position) { 
     final NoteItem noteItem = this.noteItems.get(position); 
     holder.imageButton.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       showTextOptions(holder, noteItem); 
      } 
     }); 
     holder.textView.setText(noteItem.getMessage()); 
     if (!holder.textViewSpeaker.getText().toString().isEmpty()){ 
      holder.textViewSpeaker.setText(noteItem.getSpeaker()); 
     } 


    } 

    private void showTextOptions(final NoteItemHolder holder, final NoteItem item) { 
     AlertDialog.Builder builder = new AlertDialog.Builder(context, R.style.MyDialogTheme); 
     builder.setItems(R.array.noteTextSelectionItems, new DialogInterface.OnClickListener() { 
      @Override 
      public void onClick(DialogInterface dialogInterface, int i) { 
       Log.e("tree","it is "+i); 
       if (i==0) { 

        //reference picture 
       }else if (i==1) { 

        // reference webdocument or link 
       } else if (i==2) { 
        switchViews(holder, item); 
       } else if (i==3) { 
         //delete the text 
         int n = noteItems.indexOf(item); 
         noteItems.remove(n); 
         notifyDataSetChanged(); 
       } 
      } 
     }).show(); 
    } 

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

    protected void switchViews(NoteItemHolder h, NoteItem note) { 
     if (h.textView.getVisibility()==View.GONE) { 
      //EditText editText = (EditText) context.findViewById(R.id.noteItemEditText); 
      String x = h.editText.getText().toString(); 
      h.editText.setVisibility(View.GONE); 
      //TextView textView = (TextView) context.findViewById(R.id.noteItemTextView); 
      h.textView.setText(x); 
      h.textView.setVisibility(View.VISIBLE); 
     } else { 
      // TextView textView = (TextView) context.findViewById(R.id.noteItemTextView); 
      String x = h.textView.getText().toString(); 
      h.textView.setVisibility(View.GONE); 
      //EditText editText = (EditText) context.findViewById(R.id.noteItemEditText); 
      h.editText.setText(x); 
      h.editText.setVisibility(View.VISIBLE); 
     } 
    }
