我有一个可扩展的列表视图但是当我展开它并点击该子时我收到的错误是
致命的例外：主要 处理：com.claritech.simsentinelmobile，PID：22606 java.lang.ClassCastException：android.widget.ExpandableListConnector 无法转换为com.xera.deviceinsight.home.ExpandableListAdapter
这是抛出错误的行
ExpandableListAdapter adapter = (ExpandableListAdapter)parent.getAdapter();
这是我尝试使用适配器检索对象的整个方法（使用改造从服务器中点击的子项的详细信息）
private void load(View view)
{
expListView = (ExpandableListView) view.findViewById(R.id.lvExp);
prepareListData();
listAdapter = new ExpandableListAdapter(this.getActivity(), listDataHeader, listDataChild);
expListView.setAdapter(listAdapter);
expListView.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
@Override
public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {
System.err.println("child clicked");
Toast.makeText(getActivity(), "child clicked", Toast.LENGTH_SHORT).show();
EventBus.getDefault().post(new ItemClickedEvent(SensorInformationChildFragment.TAB_CALL));
//ExpandableListAdapter adapter = (ExpandableListAdapter)parent.getAdapter();
ExpandableListAdapter adapter = (ExpandableListAdapter)parent.getAdapter();
OrganisationDeviceSensorsResult d = (OrganisationDeviceSensorsResult) adapter.getChild(groupPosition, childPosition);
d.SensorID = d.SensorID;
OrganisationDeviceSensorsResult deviceSensor = (OrganisationDeviceSensorsResult) adapter.getChild(groupPosition , childPosition);
Object contact = adapter.getChild(groupPosition , childPosition);
// OrganisationDeviceSensorsResult contact = listDataChild.get(groupPosition).getContacts().get(childPosition);
//sensorID = deviceSensor.SensorID;
//sensorID = contact.equals()
ReportingGroup.get(childPosition);
return true;
}
});
}
这是日志

答案 0 :(得分：1)
尝试在以下语句中使用完全限定的类名，即 -
listAdapter = new com.xera.deviceinsight.home.ExpandableListAdapter(this.getActivity(), listDataHeader, listDataChild);
