android 基站定位

         这里给大家分享下基站定位的实现，基站定位首先要通过TelephonyManager得到手机的信号信息，比如基站的国家编码，小区id等......得到这些后需要向google提供的接口提交这些参数，然后就会返回基站的相关信息。

废话不多说直接上代码吧：

import java.io.Serializable;import java.util.ArrayList;import java.util.List;import android.content.Context;import android.telephony.NeighboringCellInfo;import android.telephony.TelephonyManager;import android.telephony.cdma.CdmaCellLocation;import android.telephony.gsm.GsmCellLocation;import android.util.Log;/** * @author yangzhiqiang *  */public class CellIdInfoManager implements Serializable {/** *  */private static final long serialVersionUID = 5481154371450408380L;private Context context;public CellIdInfoManager(Context context) {super();this.context = context;}public List<CellInfo> getCellInfo() {List<CellInfo> listInfo = new ArrayList<CellInfo>();int countryCode;int networkCode;int areaCode;CellInfo info = new CellInfo();GsmCellLocation gsm = null;TelephonyManager manager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);if (manager.getPhoneType() == TelephonyManager.PHONE_TYPE_GSM) {gsm = (GsmCellLocation) manager.getCellLocation();if (gsm == null) {return null;}if (manager.getNetworkOperator() == null|| manager.getNetworkOperator().length() == 0) {return null;}countryCode = Integer.parseInt(manager.getNetworkOperator().substring(0, 3));networkCode = Integer.parseInt(manager.getNetworkOperator().substring(3, 5));areaCode = gsm.getLac();info.cellId = gsm.getCid();info.mobileCountryCode = countryCode;info.mobileNetworkCode = networkCode;info.locationAreaCode = areaCode;info.radio_type = "gsm";listInfo.add(info);List<NeighboringCellInfo> list = manager.getNeighboringCellInfo();for (NeighboringCellInfo i : list) {CellInfo ci = new CellInfo();ci.cellId = i.getCid();ci.mobileCountryCode = countryCode;ci.mobileNetworkCode = networkCode;ci.locationAreaCode = areaCode;ci.radio_type = "gsm";listInfo.add(ci);}} else if (manager.getPhoneType() == TelephonyManager.PHONE_TYPE_CDMA) {CdmaCellLocation cdma = (CdmaCellLocation) manager.getCellLocation();if (cdma == null) {return null;}if (manager.getNetworkOperator() == null|| manager.getNetworkOperator().length() == 0) {return null;}Log.v("TAG", "CDMA");info.cellId = cdma.getBaseStationId();info.mobileCountryCode = Integer.parseInt(manager.getNetworkOperator());info.mobileNetworkCode = cdma.getSystemId();info.locationAreaCode = cdma.getNetworkId();info.radio_type = "cdma";listInfo.add(info);}return listInfo;}public class CellInfo {// 基站编号public int cellId;// 国家代码public int mobileCountryCode;// 网络代码public int mobileNetworkCode;// 区域代码public int locationAreaCode;public String radio_type;public CellInfo() {super();}}}

上面是得到手机信号的信息，下面是将这些信息发送到google服务器并解析结果：
