スピナーを含むrecylerviewで、スピナーにアイテムを動的に追加する方法（特定の位置のみ）...今、私が子供用スピナーを更新するとき、recylerviewのすべてのスピナーは更新されています。その特定の位置（recylerviewの）のスピナーのみを更新してください。私はこのアダプタを呼び出していた場所からrecyclerviewのスピナーを更新

フラグメント：（recylerviewでこれらのスピナーを膨張さ）私のアダプタである後
offerRideRegularListViewAdapter = new OfferRideRegularListViewAdapter(getActivity(),getLeavingTimeList(),getReturningTimeList(),listEachDay);
listEachDay.setAdapter(offerRideRegularListViewAdapter);
は次のようにCustomSpinnerAdpaterです：
public class CustomSpinnerAdapter extends ArrayAdapter<CommonListViewItems> {
CommonListViewItems servicesItem;
Context context;
int layoutId;
private ArrayList<CommonListViewItems> itemsArrayList;
public CustomSpinnerAdapter(Context context, int layoutId, ArrayList<CommonListViewItems> itemsArrayList)
{
super(context,layoutId,itemsArrayList);
this.context = context;
this.layoutId=layoutId;
this.itemsArrayList=itemsArrayList;
}
@Override
public int getCount() {
return itemsArrayList.size();
}
@Override
public CommonListViewItems getItem(int position) {
return itemsArrayList.get(position);
}
@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
return getCustomView(position,convertView,parent);
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
return getCustomView(position,convertView,parent);
}
private View getCustomView(int position, View convertView, ViewGroup parent)
{
final ViewHolder holder;
if (convertView==null)
{
LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView=inflater.inflate(layoutId,parent,false);
holder=new ViewHolder();
servicesItem = new CommonListViewItems();
holder.textView=(TextView)convertView.findViewById(R.id.tv_listItems);
convertView.setTag(holder);
}
else
{
holder=(ViewHolder)convertView.getTag();
}
final CommonListViewItems servicesItem =(CommonListViewItems)itemsArrayList.get(position);
holder.textView.setText(servicesItem.getlistItem());
return convertView;
}
private class ViewHolder
{
public TextView textView;
}
}
CommonListViewItemsクラス：
public class CommonListViewItems {
String listItem;
public String getlistItem() {
return listItem;
}
public void setlistItem(String listItem) {
this.listItem = listItem;
}
}
recyclerviewは次のようになります。
と私はTimePickerDialogから複数の項目（時間）を追加したいのですが、追加項目は、各スピナーに追加取得されたスピナーをクリックすることで、Iあなたが同じspinnerAdapteの複数のインスタンスを必要とする
私は本当に試してみました。しかし、あなたのコードはとても難しく、エラーを見つけることができないのは不思議ではありません。しかし、私はすべてのあなたの意見が同じスピナーアダプターと同じデータを共有しているため、これが信じています。 –
今すぐお試しください。私は不要なコードを削除しました。今すぐお試しください...本当に必要です.. –
ViewHolderごとに1つのスピナー・アダプター・インスタンスと1つのスピナー・データを用意してください。この方法で彼らはお互いに独立しています –
