Android的基站、WIFI、GPS定位集合【源碼】

集合了gps、wifi、基站定位。

其中GPS定位首先是GpsTask類異步返回GPS經緯度信息

GpsTask gpstask = new GpsTask(GpsActivity.this,
                    new GpsTaskCallBack() {

                        @Override
                        public void gpsConnectedTimeOut() {
                            gps_tip.setText("獲取GPS超時了");
                        }

                        @Override
                        public void gpsConnected(GpsData gpsdata) {
                            do_gps(gpsdata);
                        }

                    }, 3000);
            gpstask.execute();

其中3000是設置獲取gps數據timeout時間。GpsTask是根據

locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

獲取最後一次GPS信息，如果返回為Null則是根據監聽獲取Location信息發生改變時返回的GPS信息。因為手機獲取GPS信息時間比較長，所以這個類實際使用時可能還存在一些BUG。

IAddressTask封裝了獲取地理位置的方法，具體代碼如下：
