继承ListFragment的类没有setListAdapter（）方法

package com.sudoku.ad.criminallntent;

import android.app.ListFragment
 import android.os.Bundle;
 import android.widget.ArrayAdapter;
 import java.util.ArrayList;
 import java.util.ArrayList;

 public class CrimeListFragment extends ListFragment {
 private ArrayList mCrimes;

@Override
 public void onCreate(Bundle saveInstanceState){
 super.onCreate(saveInstanceState);
 getActivity().setTitle(R.string.crimes_title);
 mCrimes = CrimeLab.get(getActivity()).getCrimes();
 }
 ArrayAdapter adapter =
 new ArrayAdapter(getActivity(),android.R.layout.simple_list_item_1,mCrimes);
 setListAdapter(adapter);
 }

在setListAdapter（adapter）那里显示有错啊！！！
