LocationManager Android自动定位使用以及注意事项（个人）

先上局部代码

/** * android 定位 */void initGoogleLocation() {if (locationListener == null) {locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);if (locationManager == null) {return;}Location lastlocation = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);if (lastlocation != null) {BMapApiApplication.userVo.setLatitude((int) (lastlocation.getLatitude() * 1e6));BMapApiApplication.userVo.setLongitude((int) (lastlocation.getLongitude() * 1e6));}locationListener = new android.location.LocationListener() {@Overridepublic void onLocationChanged(Location location) {// TODO Auto-generated method stubLog.i(BMapApiApplication.SOFTNAME, "location");if (location != null) {/** * 定位解析以及处理 */iBinder.sendPacket(new LocationPacket(location, iBinder));}}@Overridepublic void onProviderDisabled(String provider) {// TODO Auto-generated method stublocationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, location_time,20, locationListener);Log.i(BMapApiApplication.SOFTNAME, provider);}@Overridepublic void onProviderEnabled(String provider) {// TODO Auto-generated method stublocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, location_time, 20,locationListener);Log.i(BMapApiApplication.SOFTNAME, provider);}@Overridepublic void onStatusChanged(String provider, int status,Bundle extras) {// TODO Auto-generated method stub}};/** * 请求定位 */locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, location_time, 20,locationListener);} else {if (locationManager != null) {locationManager.removeUpdates(locationListener);locationListener = null;}}}

此代码为目前使用正常，不过有时候怎么都不能触发，后来发现重启手机即可，具体原因不详。

注意事项：我一请求就是GPS，而不是网络，经调试发现，如果开始请求为网络，如果软件中途开启GPS，则不能监听到GPS的开启，所以需要先GPS监听无GPS后启用网络，而如果再开启GPS的话还是能监听到的再转换GPS监听位置。网络定位经常不是受参数影响，说是最小时间最小距离，就是说有可能大于这个距离与时间,，网络定位无论怎么请求都不会有，它自动在大于这个参数时间距离后随机触发，GPS的话就是根据参数来的
