держатель ExpandableListView становится нулевым

Вот мой getChildView:держатель ExpandableListView становится нулевым

public View getChildView(int groupPosition, int childPosition, 
     boolean isLastChild, View convertView, ViewGroup parent) { 
    View v = convertView; 
    ViewHolderChild h; 
    if (v == null) { 
     h = new ViewHolderChild(); 
     switch (groupPosition) { 
     case GROUP_OVERVIEW: 
      v = inflater 
        .inflate(R.layout.adapter_show_child_overview, null); 
      h.wv_overview = (WebView) v 
        .findViewById(R.id.wv_adapter_show_child_overview); 
      h.tv_title = (TextView) v 
        .findViewById(R.id.tv_adapter_show_overview_title); 
      h.tv_date = (TextView) v 
        .findViewById(R.id.tv_adapter_show_overview_date); 
      h.tv_year = (TextView) v 
        .findViewById(R.id.tv_adapter_show_overview_year); 
      h.tv_network = (TextView) v 
        .findViewById(R.id.tv_adapter_show_overview_network); 
      h.tv_title.setTypeface(font_bold); 
      h.tv_date.setTypeface(font_thin); 
      h.tv_year.setTypeface(font_thin); 
      h.tv_network.setTypeface(font_bold); 
      v.setTag(h); 
      break; 
     case GROUP_SEASONS: 
      v = inflater.inflate(R.layout.adapter_shows_child_seasons, null); 
      h.siv = (SmartImageView) v.findViewById(R.id.siv_adapter_show_child_seasons); 
      h.tv_seasons = (TextView) v.findViewById(R.id.tv_adapter_show_child_seasons); 
      v.setTag(h); 
      break; 
     } 


    } else { 
     h = (ViewHolderChild) v.getTag(); 
    } 
    switch (groupPosition) { 
    case GROUP_OVERVIEW: 
     OverView overview = groups.get(groupPosition).getOverview(); 
     FunctionUtils.loadHtml(h.wv_overview, overview.getOverview(), 
       FunctionUtils.FONT_ROBOTO_THIN, 14); 
     h.tv_date.setText("" + overview.getAirDay() + "/" 
       + overview.getAirTime()); 
     h.tv_title.setText(overview.getTitle()); 
     h.tv_year.setText("" + overview.getYear()); 
     h.tv_network.setText("" + overview.getNetwork()); 
     break; 
    case GROUP_SEASONS: 
     SeasonObject season = groups.get(groupPosition).getSeasons().get(childPosition); 
     if(season.getImages().getPoster() != null){ 
      h.siv.setImageUrl(season.getImages().getPoster()); 
     } 
     h.tv_seasons.setText("Season : "+season.getSeason()+" Episode : "+season.getEpisodes()); 
     break; 
    } 
    return v; 
}

Но когда я начинаю прокручивать вниз, есть проблема в этой строке: h.siv.setImageUrl(season.getImages().getPoster());

Я видел журнал и говорит ч содержит все вид из GROUP_OVERVIEW и не GROUP_SEASONS

Это вызывает NullPointerException, ExpandableListConnector getView

Поскольку вы используете два типа видов детских элементов группы. Таким образом, вы должны переопределить следующие два метода

final int CHILDVIEW_TYPE_COUNT = 2; 
@Override 
public int getChildTypeCount() { 
    return CHILDVIEW_TYPE_COUNT; 
}

Из кода, два типа взглядов помечены вашей группы, я полагаю, что у Вас есть только две группы.

@Override 
public int getChildType(int groupPosition, int childPosition) 
{ 
    return groupPosition; 
}
