关于Android开发GPS程序的有关问题

关于Android开发GPS程序的问题。
写了简单的GPS程序，但是貌似模拟器的GPS没有起来。
onStatusChanged里的arg1一直=1。
Android SDK用的1.5 ADT用的0.9.1

Java code


package com.example.android.gpstest;

import java.util.List;

import android.app.Activity;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.util.Log;

public class GPSTest extends Activity implements LocationListener {

    private LocationManager lm;
    private List<String> proList;
    private Location loc;

    private String PROVIDER_NAME = "my_test_provider";
    
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 10l, 100l, this);
    }

    public void onLocationChanged(Location arg0) {
        String lat = String.valueOf(arg0.getLatitude());
        String lon = String.valueOf(arg0.getLongitude());
        Log.e("GPS", "location changed: lat=" + lat + ", lon=" + lon);
    }

    public void onProviderDisabled(String provider) {
        // TODO Auto-generated method stub
        Log.e("GPS", "The provider " + provider + " is disabled");
    }

    public void onProviderEnabled(String provider) {
        // TODO Auto-generated method stub
        Log.e("GPS", "The provider " + provider + " is enabled");
    }

    public void onStatusChanged(String arg0, int arg1, Bundle arg2) {
        if (arg1 == 0) {
            Log.e("GPS", arg0 + " is OUT OF SERVICE");
        } else if (arg1 == 1) {
            Log.e("GPS", arg0 + " is TEMPORARILY_UNAVAILABLE");
        } else {
            Log.e("GPS", arg0 + " is Available");
        }
    }
}

Android 1.5的SDK对于GPS好像有些变化，当定到GPS信号后onLocationChanged函数只调了一次，然后就再也不调用了，此时可以定时调用getLastKnownLocation函数来获得GPS定位信息。不知道这个是Android的bug还是就想设计成这个样子的，感觉总是怪怪的。呵呵
