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
