我正在创建一个包含listview的android应用程序。
在listview中，我有一个可扩展的高度列表视图。对于父列表视图，我设置了一个限制，仅显示两个列表项。但在可扩展的列表视图中，我没有设置任何限制
我想知道如何在listview中为子视图设置限制（即可扩展列表视图）。下面是listview的一个适配器的代码：
public class Daybook_adapter extends BaseAdapter {
Context context;
Activity activity;
//DaybookSwipeMenuListView daybookdetailviewlist;
public Daybook_adapter(Activity activity, ArrayList<Daybook> list) {
//this.context = context;
this.activity = activity;
entriesdaybook = list;
}
@Override
public int getCount() {
return entriesdaybook.size();
}
@Override
public Object getItem(int position) {
return entriesdaybook.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup arg2) {
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.model_daybook, null);
}
final Daybook m = entriesdaybook.get(position);
final TextView tv_date = (TextView) convertView.findViewById(R.id.tv_daybook_date);
final TextView tv_cashin = (TextView) convertView.findViewById(R.id.tv_daybook_cashin);
final TextView tv_cashout = (TextView) convertView.findViewById(R.id.tv_daybook_cashout);
final TextView tv_totalamt = (TextView) convertView.findViewById(R.id.daybook_total_amt);
final ImageView img_pdf = (ImageView) convertView.findViewById(R.id.img_printpdf);
//final String s = new SimpleDateFormat("yyyy-MM-dd").format(new Date());
String s = m.getDate();
emptyyz = (LinearLayout) convertView.findViewById(R.id.empty);
// daybookdetailviewlist = (DaybookSwipeMenuListView) convertView.findViewById(R.id.detaillist_daybook);
daybookdetailviewlist = (ExpandableHeightListView) convertView.findViewById(R.id.detaillist_daybook);
String[] spiliter = s.split("-");
String year = spiliter[0];
String month = spiliter[1];
String date = spiliter[2];
if (month.startsWith("01")) {
tv_date.setText(date + "Jan" + year);
} else if (month.startsWith("02")) {
tv_date.setText(date + "Feb" + year);
} else if (month.startsWith("03")) {

tv_date.setText(date + "Dec" + year);
}
/* if (m.getUsertype().startsWith("singleworker")) {

} else if (m.getUsertype().startsWith("groupworker")) {

tv_cashin.setText("\u20B9" + m.getCashin());

double one = Double.parseDouble(m.getCashin());

// new DaybooklistAsynccTask().execute(s);

if (adapter != null) {
if (adapter.getCount() > 0) {

daybookdetailviewlist.setAdapter(adapter);
}
} else {
daybookdetailviewlist.setEmptyView(emptyyz);
}
daybookdetailviewlist.setExpanded(true);
img_pdf.setOnTouchListener(new View.OnTouchListener() {
