Android新人求解：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！！！
