这几天在做基站定位，发觉CDMA的基站定位在网上资料很少。经过漫长的摸索，其中的小小收获给大家分享一下！
这个是CDMA中国电信的基站定位获取经纬度的源码及测试截图！在模拟器中用似乎不行，模拟器的网络不是CDMA的。有知道的请指点指点！
主要代码：
public void onClick(View v) {
// TODO Auto-generated method stub
tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
//int type = tm.getNetworkType();
//if (type ==TelephonyManager.NETWORK_TYPE_CDMA) {
location = (CdmaCellLocation) tm.getCellLocation();
if(location == null)
return;
int sid = location.getSystemId();//系统标识 mobileNetworkCode
int bid = location.getBaseStationId();//基站小区号 cellId
int nid = location.getNetworkId();//网络标识 locationAreaCode
Log.i("sid:", "" + sid);
Log.i("bid:", "" + bid);
Log.i("nid:", "" + nid);
ArrayList<CellIDInfo> CellID = new ArrayList<CellIDInfo>();
CellIDInfo info = new CellIDInfo();
info.cellId = bid;
info.locationAreaCode = nid;
info.mobileNetworkCode = String.valueOf(sid);
info.mobileCountryCode = tm.getNetworkOperator().substring(0, 3);
info.mobileCountryCode = tm.getNetworkOperator().substring(3, 5);
info.radioType = "cdma";
CellID.add(info);
Log.d("cellId:", "" + info.cellId);
Log.d("locationAreaCode:", "" + info.locationAreaCode);
Log.d("mobileNetworkCode:", info.mobileNetworkCode);
Log.d("mobileCountryCode:", info.mobileCountryCode);
Location loc = callGear(CellID);
if (loc !=null)
mTextView.setText("纬度：" + loc.getLatitude() + "\\n经度：" + loc.getLongitude());
//}// end if
}// end onclick
//调用google gears的方法，该方法调用gears来获取经纬度
