비슷한 스레드를 검색했지만 도움이되지 않았지만 가벼워 졌거나 아직 대답이 없으므로 문제를 설명 할 것입니다. GetChildView가 호출되지 않았습니다.
은 내가custom
ExpandableListAdapter과
ExpandableListView을하고 난 내
Groups하지만
Children 내를 표시 할 수 있습니다.
GetChildView 어쨌든 호출되지 않습니다.
귀하의 도움에 감사드립니다.

그래서, 내 어댑터 데이터 만을 얻는 것을 얻을 변하기 쉬운 client (ExpandableListView)은 올바르게 설정했지만 데이터가 있음을 인식하지 못합니다.

레이아웃 EDIT (2) : 그렇듯이 레이아웃의 문제는 없습니다. ClientAdapter , 그래서 그것은
...이 예
public class ClientActivity2 extends Activity{
private ExpandableListView client;
private ClientAdapter client_adapter;
private ArrayList children;
private ArrayList<String> groups;
private LayoutInflater inflater;
private LinearLayout lin_layout_probe;
private Context context;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.field_list);
context = getApplicationContext();
prepareData();
ExpandableListView client = (ExpandableListView)findViewById(R.id.field_expandable_list);
client_adapter = new ClientAdapter(context, groups, children);
client.setAdapter(client_adapter);
client.expandGroup(0);
}
private void prepareData() {
children = new ArrayList();
HashMap<String,Object> hm1 = new HashMap<String,Object>();
hm1.put(Constants._FIELDNAME,"Child1");
children.add(hm1);
HashMap<String,Object> hm2 = new HashMap<String,Object>();
hm2.put(Constants._FIELDNAME,"Child2");
children.add(hm2);
HashMap<String,Object> hm3 = new HashMap<String,Object>();
hm3.put(Constants._FIELDNAME,"Child3");
children.add(hm3);
groups = new ArrayList<String>();
groups.add("Group1");
}
}
이 지금은 나를 혼란 무엇을 오는에 잘 작동 나는 간단한 활동 모든 (어댑터와 같은 통화)를 테스트하는 경우 클릭 레이아웃이 기본 레이아웃에 TextView 인 경우 제대로 작동합니다.
나는이 텍스트 뷰를 클릭하면 다음과 ExpandableListView 프롬프트 제대로 Group 및 Children을 채워 그들이 expandable/collapsable이다.
내가 그 Item 의 ExpandableListView는 다음 그룹이 아이들을 채워 아닌 것을 클릭하면 내 마지막 (A ListView 항목에 포함 ExpandableListView) 포스트 hier, 그래서, ExpandableListView 프롬프트처럼 테스트합니다. GetChildView은 결코 호출되지 않습니다! (LogCat을 사용했기 때문에 완전히 확신합니다)
많은 사람들이 ListViewItems의 ExpandableListViews에서 클릭에 문제가 있었고, 제 경우가 다릅니다. TextView가 내 사용자 정의 BaseExpandableListAdapter을 통해 ExpandableListView Population을 작동하지만, ListView 항목이 아닌 것은 왜 잘 작동하는지 이해할 수 있습니다.
나는 기록했는데, 대신에'getChildView'는''ListView'의'getView'에 기록됩니다. –
