关于定位的问题，整的自己快疯了，googlemap问题

[麦田捕手]

下了“深入浅出google android”这本书中的有关googlemap相关的几个demo源码，其中一个最简单的是获取当前经纬度，
就一个类，

public class CurrentLocation extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        LocationManager locationManager;
        String serviceName = Context.LOCATION_SERVICE;
        locationManager = (LocationManager)getSystemService(serviceName);
        //String provider = LocationManager.GPS_PROVIDER;
        
        Criteria criteria = new Criteria();
        criteria.setAccuracy(Criteria.ACCURACY_FINE);
        criteria.setAltitudeRequired(false);
        criteria.setBearingRequired(false);
        criteria.setCostAllowed(true);
        criteria.setPowerRequirement(Criteria.POWER_LOW);
        String provider = locationManager.getBestProvider(criteria, true);
        
        Location location = locationManager.getLastKnownLocation(provider);
        updateWithNewLocation(location);
        locationManager.requestLocationUpdates(provider, 2000, 10,
        		locationListener);
    }
   private final LocationListener locationListener = new LocationListener() {
    	public void onLocationChanged(Location location) {
    	updateWithNewLocation(location);
    	}
    	public void onProviderDisabled(String provider){
    	updateWithNewLocation(null);
    	}
    	public void onProviderEnabled(String provider){ }
    	public void onStatusChanged(String provider, int status,
    	Bundle extras){ }
    };
    private void updateWithNewLocation(Location location) {
    	String latLongString;
    	TextView myLocationText;
    	myLocationText = (TextView)findViewById(R.id.myLocationText);
    	if (location != null) {
    	double lat = location.getLatitude();
    	double lng = location.getLongitude();
    	latLongString = "纬度:" + lat + "\n经度:" + lng;
    	} else {
    	latLongString = "无法获取地理信息";
    	}
    	myLocationText.setText("您当前的位置是:\n" +
    	latLongString);
    }
}

我直接倒入到eclipse里，然后通过真机测试，竟然提示“无法获取地理信息”（G5，设置正常），模拟器测试也是“无法获取地理信息”，不知道怎么回事，请高手指点指点（相关源码）

楼主的机器是有GPS模组的吗？

不知道上面这东西有帮助没

[l896993615]

应该需要加载GPS模块里面的经纬过来吧，

[凉凉二点凉]

哦，对了，我的测试环境为moto的里程碑

[纠结的木棉花]

我觉得这个是由于google的好多网站都被封了，别的baidu在模拟器上面都能运行，但是google则打不开

好像检测不到信息

[ameyume]

貌似，经纬度也不是每次都能查询到，用经纬度查询一个城市的天气时，精度相差几分都不行，有的能查到，有的查不到，而且同一个经纬度，在不同的时间里能否查到也不一样。

[Serena_mm]

这个问题也困扰了我很久，一直没找到答案，帮顶~

[zgycsmb]

楼主，我也需要实现此功能，
你能把此例子发一份给我email吗 [e-mail] thanks
