당신의 mainactivity
추가에
public ExpandableListAdapter(Context context, List<String> listDataHeader,
HashMap<String, List<String>> listChildData, ExpandableListView exp) {
this._context = context;
this._listDataHeader = listDataHeader;
this._listDataChild = listChildData;
this.exp = exp;
}
: 같은 public ExpandableListAdapter
그래서 당신은 볼 것이다 그래서 구문 분석 할 때 ExpandableListview
는 뭔가 살펴 보겠습니다 당신에 의해 분할 높이를 설정할 수 있습니다 마침내
ExpandableListAdapter mylistadapter = new ExpandableListAdapter(this, listDataHeader, listDataChild, expListView);
:
exp.setDividerHeight(10);
