Fragment无法进行高德定位，求解决！

同样的方法在Activity里可以正常显示，但在Fragment里只加载出了地图，无法显示定位。应该是Fragment的问题。求大神教育！
public class ParkFragment extends Fragment implements
LocationSource AMapLocationListener OnCheckedChangeListener{

    private MapView mapView;
    private AMap aMap;
    private OnLocationChangedListener mListener;
    private LocationManagerProxy mAMapLocationManager;
    private ImageView imglist;

    @Override
    public View onCreateView(LayoutInflater inflater ViewGroup container
                    Bundle savedInstanceState) {
            View view = inflater.inflate(R.layout.tab01 container false);

            imglist = (ImageView) view.findViewById(R.id.imglist);
            imglist.setOnClickListener(new OnClickListener() {

                    @Override
                    public void onClick(View v) {
                            Intent intent = new Intent(getActivity() ParklistActivity.class);
                            startActivity(intent);
                    }
            });

            //在onCreate方法中给aMap对象赋值
            mapView = (MapView) view.findViewById(R.id.map);
            mapView.onCreate(savedInstanceState);// 必须要写
            aMap = mapView.getMap();
            return view;

            }
    }

    public void setUpMap() {
            aMap.setLocationSource((LocationSource) getActivity());// 设置定位监听
            aMap.getUiSettings().setMyLocationButtonEnabled(true);// 设置默认定位按钮是否显示
            aMap.setMyLocationEnabled(true);// 设置为true表示显示定位层并可触发定位，false表示隐藏定位层并不可触发定位，默认是false
            aMap.setMyLocationType(AMap.LOCATION_TYPE_LOCATE);
    }

                    //此方法为每隔固定时间会发起一次定位请求，为了减少电量消耗或网络流量消耗，
                    //注意设置合适的定位时间的间隔，并且在合适时间调用removeUpdates()方法来取消定位请求
                    //在定位结束后，在合适的生命周期调用destroy()方法
                    //其中如果间隔时间为-1，则定位只定一次
                    mAMapLocationManager.requestLocationData(
                                    LocationProviderProxy.AMapNetwork 60*1000 10 this);
            }
    }

    /**

    @Override
    public void deactivate() {
            mListener = null;
            if (mAMapLocationManager != null) {
                    mAMapLocationManager.removeUpdates(this);
                    mAMapLocationManager.destroy();
            }
            mAMapLocationManager = null;
    }

    @Override
    public void onStatusChanged(String provider int status Bundle extras) {
            // TODO Auto-generated method stub

    }

    @Override
    public void onProviderEnabled(String provider) {
            // TODO Auto-generated method stub

    }

    @Override
    public void onProviderDisabled(String provider) {
            // TODO Auto-generated method stub

    }

    @Override
    public void onCheckedChanged(RadioGroup group int checkedId) {
            // TODO Auto-generated method stub

    }

解决方案

可以 SupportMapFragment和MapFragment
