i logend，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，我无法发布图片）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日期时间（1月12日）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，我只能显示第一个日期时间12月12日。我不知道我的baseadapter有什么问题。如果有人知道解决方案，请帮助我感谢

删除ViewHolder提取周围的} else块。将Holder初始化移动到if{块之后。现在试试。

if (convertView == null) {

    LayoutInflater inflater = ((Activity) mContext).getLayoutInflater();
    convertView = inflater.inflate(R.layout.cinema_holl_adapter,
            parent, false);

    ViewHolderItem newViewHolder = new ViewHolderItem();
    newViewHolder.start_time = (TextView) convertView
            .findViewById(R.id.adapter_day);

    convertView.setTag(newViewHolder);

}

ViewHolderItem viewHolder = (ViewHolderItem) convertView.getTag(); //This should be called always

/* Rest of your code */

编辑：这个街区做了什么？

if (position < objectItem.getStartTimePeriod().size()) {
        String starttimes = objectItem.getStartTimePeriod().get(
                position);

        viewHolder.start_time.setText(starttimes);

}

android基础适配器不适配所有行
