Android编程实现GPS位置获取的方法

 public class GPSInfoService { private static GPSInfoService mInstance; private LocationManager locationManager;//定位服务 private GPSInfoService(Context context) { // TODO Auto-generated constructor stub locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE); } public static GPSInfoService getInstance(Context context){ if(mInstance == null){ mInstance = new GPSInfoService(context); } return mInstance; } //注册定位监听 public void registenerLocationChangeListener(){ //得到所有的定位服务 //   List providers = locationManager.getAllProviders(); //   for(String provider:providers){ //     Log.i("i", provider); //   } //查询条件 Criteria criteria = new Criteria(); //定位的精准度 criteria.setAccuracy(Criteria.ACCURACY_FINE); //海拔信息是否关注 criteria.setAltitudeRequired(false); //对周围的事情是否进行关心 criteria.setBearingRequired(false); //是否支持收费的查询 criteria.setCostAllowed(true); //是否耗电 criteria.setPowerRequirement(Criteria.POWER_LOW); //对速度是否关注 criteria.setSpeedRequired(false); //得到最好的定位方式 String provider = locationManager.getBestProvider(criteria, true); //注册监听 locationManager.requestLocationUpdates(provider, 60000, 0, getListener()); } //取消监听 public void unRegisterLocationChangeListener(){ locationManager.removeUpdates(getListener()); } private MyLocationListener listener; //得到定位的监听器 private MyLocationListener getListener(){ if(listener == null){ listener = new MyLocationListener(); } return listener; } //得到上个地理位置 public String getLastLocation(){ return sp.getString("last_location", ""); } private final class MyLocationListener implements LocationListener{ //位置的改变 public void onLocationChanged(Location location) { // TODO Auto-generated method stub double latitude = location.getLatitude();//维度 double longitude = location.getLongitude();//经度 String last_location = "jingdu: " + longitude + ",weidu:" + latitude; Editor editor = sp.edit(); editor.putString("last_location", last_location); editor.commit(); } //gps卫星有一个没有找到 public void onStatusChanged(String provider, int status, Bundle extras) { // TODO Auto-generated method stub } //某个设置被打开 public void onProviderEnabled(String provider) { // TODO Auto-generated method stub } //某个设置被关闭 public void onProviderDisabled(String provider) { // TODO Auto-generated method stub } } }
