[發問]怎麼讓Google map結合GPS (41528)

package com.test.map;

import android.location.Location;

import android.os.Bundle;

import android.view.Window;

import android.view.WindowManager;

import com.google.android.maps.*;

public class Gmap extends MapActivity {

static final int INITIAL_ZOOM_LEVEL = 13;

//初始位置

static final int INITIAL_LATITUDE = 24150000;

static final int INITIAL_LONGITUDE = 120684000;

MapController mc;

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

//程式外觀

requestWindowFeature(Window.FEATURE_NO_TITLE);

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,

WindowManager.LayoutParams.FLAG_FULLSCREEN);

setContentView(R.layout.main);

//取得位置

//顯示地圖

MapView mapView = (MapView) findViewById(R.id.mapview);

mapView.setBuiltInZoomControls(true);

mc = mapView.getController();

mc.setZoom(INITIAL_ZOOM_LEVEL);

mc.setCenter(new GeoPoint(INITIAL_LATITUDE,INITIAL_LONGITUDE));

}

@Override

protected boolean isRouteDisplayed() {

return false;

}

public void onLocationChanged(Location location) {

GeoPoint gp =

new GeoPoint((int)(location.getLatitude()*1E6),(int)(location.getLongitude()*1E6));

mc.animateTo(gp);

}

以上是我目前的程式碼

我想問的是要如何取得位置

之前有打這段程式碼：

LocationManager mLocationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);

mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);

可是在模擬器上run時又不行

又找不出什麼錯誤(註：在打那段程式碼時只有加一些不會打擾原程式碼的內容)

所以請教一下大大們

定位那段程式碼該填什麼?

或者是該修改甚麼?
