android gps ，wifi ，基站定位集合

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();

复制代码 其中3000是设置获取gps数据timeout时间。GpsTask是根据

locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

复制代码

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：
