gps、wifi、基站定位
集合了gps、wifi、基站定位。其中GPS定位首先是GpsTask类异步返回GPS经纬度信息
01.GpsTask gpstask = new GpsTask(GpsActivity.this,new GpsTaskCallBack() { @Override 02.public void gpsConnectedTimeOut() { 03.gps_tip.setText("获取GPS超时了"); 04.} 05.@Override 06.public void gpsConnected(GpsData gpsdata) { 07.do_gps(gpsdata); 08.} 09.}, 3000); 10.gpstask.execute();其中3000是设置获取gps数据timeout时间。GpsTask是根据
01.locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);获取最后一次GPS信息，如果返回为Null则是根据监听获取Location信息发生改变时返回的GPS信息。因为手机获取GPS信息时间比较长，所以这个类实际使用时可能还存在一些BUG。
IAddressTask封装了获取地理位置的方法，具体代码如下：
