Android ExpandableListView y onChildClick no funciona

He estado leyendo un montón de temas con el mismo problema que tengo, pero no puedo entender lo que está sucediendo. Tengo una vista de lista expandible, pero no puedo hacer que el onChildClickListener funcione. El onGroupClickListener está funcionando bien, pero realmente no lo necesito. Miré muchos ejemplos y todos parecen ser como los míos. Aquí está el código:

import android.app.Activity; import android.app.ExpandableListActivity; import android.content.Context; import android.os.Bundle; import android.util.Log; import android.view.Menu; import android.view.View; import android.widget.AdapterView; import android.widget.ExpandableListView; import android.widget.ExpandableListView.OnChildClickListener; import android.widget.ExpandableListView.OnGroupClickListener; import android.widget.ListView; import android.widget.Toast; import org.ektorp.CouchDbConnector; import org.ektorp.DbAccessException; import org.ektorp.android.util.EktorpAsyncTask; import java.util.ArrayList; import java.util.Arrays; import java.util.List; import android.widget.TextView; public class MainActivity extends Activity { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); EktorpAsyncTask getUsersTask = new EktorpAsyncTask() { @Override protected void doInBackground() { //here i connect to de BD and fill the Group and Children arrays } @Override protected void onSuccess() { UserArrayExpandableAdapter adapter = new UserArrayExpandableAdapter(getApplicationContext(),parentsChilds.getParents(), parentsChilds.getChilds()); ExpandableListView expandableList = (ExpandableListView) findViewById(R.id.userview); expandableList.setAdapter(adapter); expandableList.setClickable(true); expandableList.setOnGroupClickListener(new OnGroupClickListener(){ @Override public boolean onGroupClick(ExpandableListView arg0, View arg1, int groupPosition, long arg3) { return false; } }); expandableList.setOnChildClickListener(new OnChildClickListener() { @Override public boolean onChildClick(ExpandableListView arg0, View arg1, int arg2, int arg3, long arg4) { Toast.makeText(getBaseContext(), "Child clicked", Toast.LENGTH_LONG).show(); return false; } });

Código del adaptador:

 public class UserArrayExpandableAdapter extends BaseExpandableListAdapter { private final Context context; private final ArrayList<ArrayList<EventVO>> childs; private ArrayList<String> parents; public UserArrayExpandableAdapter(Context context, ArrayList<String> parents,ArrayList<ArrayList<EventVO>> childs) { this.context = context; this.childs = childs; this.parents = parents; } @Override public Object getChild(int arg0, int arg1) { return childs.get(arg0).get(arg1); } @Override public long getChildId(int groupPosition, int childPosition) { return childPosition; } @Override public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) { List<EventVO> child = (ArrayList<EventVO>) childs.get(groupPosition); if (convertView == null){ LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView = inflater.inflate(R.layout.user_view, parent, false); } TextView nameView = (TextView) convertView.findViewById(R.id.name); TextView dateView = (TextView) convertView.findViewById(R.id.day); TextView subjectView = (TextView) convertView.findViewById(R.id.subject); nameView.setText(child.get(childPosition).getName()); String day = child.get(childPosition).getDate(); day = DateTransformer.getDay(day); dateView.setText(day); subjectView.setText(child.get(childPosition).getSubject()); return convertView; } @Override public int getChildrenCount(int groupPosition) { return childs.get(groupPosition).size(); } @Override public Object getGroup(int groupPosition) { return parents.get(groupPosition); } @Override public int getGroupCount() { return parents.size(); } @Override public long getGroupId(int groupPosition) { return groupPosition; } @Override public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) { if (convertView==null) { LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView = inflater.inflate(R.layout.parent_view, parent, false); } TextView monthView = (TextView) convertView.findViewById(R.id.monthText); monthView.setText(parents.get(groupPosition)); return convertView; } @Override public boolean hasStableIds() { return true; } @Override public boolean isChildSelectable(int groupPosition, int childPosition) { return true; } } 

Muchas gracias.
