ExpandableListView在“setAdapter”崩溃

Question

运行时错误：java.lang.RuntimeException：对于ExpandableListView，使用setAdapter（ExpandableListAdapter）而不是setAdapter（ListAdapter）

但我正在调用setAdapter(ExpandableListAdapter)，因为我的适配器扩展了BaseExpandableListAdapter。有谁知道可能是什么问题？

适配器：

import android.content.Context;
import android.view.Gravity;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AbsListView;
import android.widget.BaseExpandableListAdapter;
import android.widget.TextView;

public class MyExpandableListAdapter extends BaseExpandableListAdapter {

Context mContext;

public MyExpandableListAdapter(Context context){
    this.mContext = context;
}

// Sample data set. children[i] contains the children (String[]) for
// groups[i].
private String[] groups = { "GroupItems 0", "GroupItems 1",
        "GroupItems 2", "GroupItems 3" };
private String[][] children = {
        { "SubItem 0", "SubItem 1", "SubItem 2", "SubItem 3" },
        { "SubItem 0", "SubItem 1", "SubItem 2", "SubItem 3" },
        { "SubItem 0", "SubItem 1" },
        { "SubItem 0", "SubItem 1", "SubItem 2", } };

public Object getChild(int groupPosition, int childPosition) {
    return children[groupPosition][childPosition];
}

public long getChildId(int groupPosition, int childPosition) {
    return childPosition;
}

public int getChildrenCount(int groupPosition) {
    return children[groupPosition].length;
}

public TextView getGenericView() {
    // Layout parameters for the ExpandableListView
    AbsListView.LayoutParams lp = new AbsListView.LayoutParams(
            ViewGroup.LayoutParams.MATCH_PARENT, 64);

    TextView textView = new TextView(mContext);
    textView.setLayoutParams(lp);
    // Center the text vertically
    textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.LEFT);
    // Set the text starting position
    textView.setPadding(36, 0, 0, 0);
    return textView;
}

public View getChildView(int groupPosition, int childPosition,
                         boolean isLastChild, View convertView, ViewGroup parent) {
    TextView textView = getGenericView();
    textView.setText(getChild(groupPosition, childPosition).toString());
    return textView;
}


public Object getGroup(int groupPosition) {
    return groups[groupPosition];
}

public int getGroupCount() {
    return groups.length;
}

public long getGroupId(int groupPosition) {
    return groupPosition;
}

public View getGroupView(int groupPosition, boolean isExpanded,
                         View convertView, ViewGroup parent) {
    TextView textView = getGenericView();
    textView.setText(getGroup(groupPosition).toString());
    return textView;
}

public boolean isChildSelectable(int groupPosition, int childPosition) {
    return true;
}

public boolean hasStableIds() {
    return true;
}
}

片段：

import android.app.ListFragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ExpandableListView;

public class PickTimeFragment extends Fragment {

public PickTimeFragment() {
    // Required empty public constructor
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.fragment_pick_time, container, false);
    ExpandableListView elv = (ExpandableListView) view.findViewById(R.id.expandableListView);
    MyExpandableListAdapter listAdapter = new MyExpandableListAdapter(getActivity());
    elv.setAdapter(listAdapter);
    return view;
}
