Android的基站、WIFI、GPS定位集合【源码】
来源：互联网 发布：网络销售平台策划方案 编辑：程序博客网 时间：2024/04/29 19:26
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

GpsTask gpstask = new GpsTask(GpsActivity.this, new GpsTaskCallBack() { @Override public void gpsConnectedTimeOut() { gps_tip.setText("获取GPS超时了"); } @Override public void gpsConnected(GpsData gpsdata) { do_gps(gpsdata); } }, 3000); gpstask.execute();
其中3000是设置获取gps数据timeout时间。GpsTask是根据
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：
