对于MapFragment类型,未定义getSupportFragmentManager()方法

Question

我正在尝试实施Google地图显示,下面是我的代码:

package com.fragments;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;

public class MapFragment extends SherlockMapFragment {

    private GoogleMap mMap;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View root = super.onCreateView(inflater, container, savedInstanceState);
        SupportMapFragment mapFrag= (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.fragment_map);
        mMap = mapFrag.getMap();
        return root;
    }
}

我得到一个错误,getSupportFragmentManager()未定义类型MapFragment.但是我有点困惑,因为我导入了com.google.android.gms.maps.SupportMapFragment.那个方法不应该来自那里吗？我错过了让这种方法起作用的一些步骤吗？

如果您使用此SherlockMapFragment,请尝试:

getSherlockActivity().getSupportFragmentManager();
