【问题描述】：
我有两个日期时间 12/01/2014 和 12/10/2014。我更改了日期时间格式，我还检查了两个日期时间之间的差异，我还增加了两个日期时间之间的天数。了解更多信息 12 月 1 日、2 月 2 日、12 月 3 日 .....12 月 10 日 这是我的来源

} 这是我的 baseadapter xml 代码

我登录，我可以在日志中显示所有信息。this is a my log cat result（我是新用户，我不能发布图片） 在我的选项中，我的 baseadapter 有问题，因为在适配器中我只能显示第一个 datetime(1 dec) 这是我的基本适配器代码
public class HollAdapters extends BaseAdapter {
private Context mContext;
private final ArrayList<CinemaInfoModel> hollitems;
public HollAdapters(Context context, ArrayList<CinemaInfoModel> hollitems) {
mContext = context;
this.hollitems = hollitems;
}
@Override
public int getCount() {
return hollitems.size();
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return position;
}
@SuppressLint("ViewHolder")
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolderItem viewHolder;
if (convertView == null) {
LayoutInflater inflater = ((Activity) mContext).getLayoutInflater();
convertView = inflater.inflate(R.layout.cinema_holl_adapter,
parent, false);
viewHolder = new ViewHolderItem();
viewHolder.start_time = (TextView) convertView
.findViewById(R.id.adapter_day);
convertView.setTag(viewHolder);
}
viewHolder = (ViewHolderItem) convertView.getTag();
CinemaInfoModel objectItem = hollitems.get(position);
if (objectItem != null) {
if (position < objectItem.getStartTimePeriod().size()) {
String starttimes = objectItem.getStartTimePeriod().get(
position);
viewHolder.start_time.setText(starttimes);
}
}
return convertView;
}
static class ViewHolderItem {
private TextView start_time;
}
}
this is a my divice's screenshot 正如我所说，我只能显示 12 月 1 日的第一个日期时间。我不知道我的 baseadapter 出了什么问题。如果有人知道解决方案，请帮助我 谢谢
