Android：ListViewの行にある特定のウィジェットに、クリック可能なスパンをクリックすると表示されます

Question

ここには、ListViewという行のウィジェットはほとんどありません。

私はウィジェットの正しい位置を取得し、アダプター内の視認性を管理する必要があります。現在のところ、ListViewのlast itemに表示されています。

ここでもgetTag()とsetTag()を使用していますが、成功していません。この問題については

@Override 
public View getView(final int position, View convertView, final ViewGroup parent) { 
    if (convertView == null) { 
     LayoutInflater inflater = (LayoutInflater) activity 
       .getSystemService(activity.LAYOUT_INFLATER_SERVICE); 
     convertView = inflater.inflate(R.layout.clist_item, null); 
     holder = new ViewHolder(); 
holder.requestion_layout = (RelativeLayout) convertView.findViewById(R.id.requestion_layout); 
holder.submitAnswerBtn = (RelativeLayout) convertView.findViewById(R.id.submit_answer_btn); 
holder.questionTitle = (TextView) convertView.findViewById(R.id.question_title); 
//these are the widgets 
    holder.requestion_layout.setTag(position); 
    holder.submitAnswerBtn.setTag(position); 
     convertView.setTag(holder); 
    } else { 
     holder = (ViewHolder) convertView.getTag(); 
    } 


//trying to change visibility on click of Clickable Span 
Spannable main_words = new SpannableString(items.get(position).getAnswer() + ""); 
     int color1 = ContextCompat.getColor(activity, R.color.light_black); 
     main_words.setSpan(new ForegroundColorSpan(color1), 0, main_words.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); 
     int color2 = ContextCompat.getColor(activity, R.color.tab_green); 
     Spannable wordTwo = new SpannableString("Reply"); 
     ClickableSpan clickableSpan = new ClickableSpan() { 
      @Override 
      public void onClick(View textView) { 
       //Toast.makeText(DummyActivity.this, "Click", Toast.LENGTH_LONG).show(); 
      Integer position_clicked = (Integer) v.getTag(); 
      //Widgets are not getting their positions here 
       holder.requestion_layout.setVisibility(View.VISIBLE); 
       holder.submitAnswerBtn.setVisibility(View.VISIBLE); 
      } 
     }; 
     wordTwo.setSpan(clickableSpan, 0, wordTwo.toString().length(), Spanned.SPAN_INCLUSIVE_INCLUSIVE); 
     wordTwo.setSpan(new ForegroundColorSpan(color2), 0, wordTwo.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); 
     wordTwo.setSpan(new StyleSpan(Typeface.ITALIC), 0, wordTwo.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); 
     CharSequence concat = TextUtils.concat(main_words, " ", wordTwo); 
     holder.answerValue.setText(concat); 
     holder.answerValue.setMovementMethod(LinkMovementMethod.getInstance()); 
     holder.answerValue.setHighlightColor(Color.TRANSPARENT); 
     holder.answerValue.setVisibility(View.VISIBLE); 
     holder.answerTitle.setVisibility(View.VISIBLE); 
return convertView; 
}

あなたはarrayListを使用して、私はそれがあなたのために働くいただければ幸い

//Define arraylist globally 
private List<Boolean> requestionVisibleState; 

//set a default value in constructor of adapter 
this.requestionVisibleState = new ArrayList<>(Arrays.asList(new Boolean[getCount()])); 
    Collections.fill(this.requestionVisibleState, false); 

//In getView after completing if else statement 
if (requestionVisibleState.get(position)) { 
     holder.submitAnswerBtn.setVisibility(View.VISIBLE); 
     holder.requestion_layout.setVisibility(View.VISIBLE); 
    } 
//And in `onClick` of your ClicableSpan 
        if (requestionVisibleState.get(position)) { 
         requestionVisibleState.set(position, false); 
        } else { 
         requestionVisibleState.set(position, true); 
        } 
        notifyDataSetChanged(); 

として位置とそこにフラグを設定する必要があります。
