GetView空指针异常

我已经实现了自定义的listview显示餐厅的详细信息。当我安装为新应用程序时，它运行良好。在它不断崩溃之后。我的问题和答案类似于我在stackoverflow中的问题。我尝试了这些答案。但它不适合我。我该如何解决这个问题？在此先感谢。GetView空指针异常

这是我的代码

public class RestaurantAdapter extends BaseAdapter{ 
    String hotelName, partySize, searchByTime; 
    ArrayList<String> urlList, timeList, offerList; 
    Context context; 
    ViewHolder holder; 
    LayoutInflater inflater; 
    RestaurantData obj; 
    ArrayList<RestaurantData> dataList; 

public RestaurantAdapter(Context con, ArrayList<RestaurantData> list, 
     String searchTime) { 
    context = con; 
    dataList = list; 
    inflater = (LayoutInflater) con 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    searchByTime = searchTime; 
} 

@Override 
public int getCount() { 
    return dataList.size(); 
} 

@Override 
public Object getItem(int arg0) { 
    return null; 
} 

@Override 
public long getItemId(int pos) { 
    return pos; 
} 

public class ViewHolder { 
    public TextView tv_hotel, tv_party_label, tv_party_value; 
    public Gallery gallery; 
    public LinearLayout ll_time; 
    public ProgressBar progress; 
    public HorizontalScrollView hsv; 
} 

@SuppressLint({ "ViewHolder", "InflateParams", "NewApi", "CutPasteId" }) 
@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    View vi = convertView; 
    SessionManager sesObj = new SessionManager(context); 
    holder = new ViewHolder(); 
    if (sesObj.isSearchLayoutVisible() == 0) { 
     obj = dataList.get(position); 
     LayoutInflater inflater = (LayoutInflater) context 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     if (vi == null) { 
      vi = inflater.inflate(R.layout.restaurant_item, parent, false);  
      holder.ll_time = (LinearLayout) vi.findViewById(R.id.ll_timer);

     } 

     holder.tv_hotel.setText(obj.hotelName); 
     holder.tv_party_value.setText(obj.partySize); 
     holder.gallery.setAnimationDuration(10); 
     holder.gallery.setTag(position); 
     holder.tv_hotel.setTag(position); 
     holder.gallery.setAdapter(new GalleryImageAdapter(context, 
       obj.urlList)); 
     timeList = obj.timeList; 
     offerList = obj.offerList; 
     for (int i = 0; i < timeList.size(); i++) { 
      View viewTime = inflater.inflate(R.layout.time_item, null);

      btn_time.setTag(position + "-" + offerList.get(i));   
      holder.ll_time.addView(viewTime); 
     } 
    } 
    return vi; 
} 


private class GalleryImageAdapter extends BaseAdapter {
