嗨有和可擴展的列表視圖，每擴展時只有一個孩子與一些EditText裏面。問題是，當我展開一個標題並將某些內容放在edittext上時，當我展開另一個標題時，我放入的值就是另一個標題的原始標題。我知道ListViews在滾動時重用視圖，並且我放置了ViewHolders，但我無法使其工作。EditText轉到另一個孩子上ExpandableListView
這裏是我的CustomAdapter代碼：
public class ExpandableListAddDataAdapter extends BaseExpandableListAdapter {
private Context _context;
private List<String> _listDataHeader = new ArrayList<>(); // header titles
private Date sportsDate, medsDate, glucoseDate, mealDate, auxDate;
public ExpandableListAddDataAdapter(Context context, List<String> listDataHeader) {
this._context = context;
this._listDataHeader = listDataHeader;
this.sportsDate = new Date(1900,1,1);
this.medsDate = new Date(1900,1,1);
this.glucoseDate = new Date(1900,1,1);
this.mealDate = new Date(1900,1,1);
this.auxDate = new Date(1900,1,1);
}
@Override
public String[] getChild(int groupPosition, int childPosititon) {
return null;

@Override

mDatePicker.show();

});

private static class ChildViewHolder {
EditText txtDate;
EditText txtTime;
EditText txtGlucose;
ChildViewHolder(View v)
{
txtDate = (EditText) v.findViewById(R.id.input_event_date);
txtTime = (EditText) v.findViewById(R.id.input_event_time);
txtGlucose = (EditText) v.findViewById(R.id.input_glucose);
}
}
private static class HeaderViewHolder {
TextView txtHeader;
ImageView expandIndicator;
HeaderViewHolder(View v)
{
txtHeader = (TextView) v.findViewById(R.id.expandable_add_data_header_text);
expandIndicator = (ImageView) v.findViewById(R.id.expandable_add_data_header_icon);
}
}
}
這是一些screenshoots的問題，我現在面臨
The first header expanded with the edittext
Second header expanded and the value of the firt edittext goes to the second header child
