所以部分童鞋的SIM卡网络制式不在这7种之内，自己根据实际情况看看它是归类于GSM还是CDMA在添进去就可以了
网络上多数教程是讲GSM网获取基站的，而忽略了C网的基站
这里我们可以比较一下GSM 和 CDMA 在获取基站信息时的不同之处
GSM:
int lac = gsm.getLac();
String mcc = manager.getNetworkOperator().substring(0, 3);
String mnc = manager.getNetworkOperator().substring(3, 5);
int cid = gsm.getCid();
CDMA:
int lac = cdma.getNetworkId();
String mcc = manager.getNetworkOperator().substring(0, 3);
String mnc = String.valueOf(cdma.getSystemId());
int cid = cdma.getBaseStationId();
在获取区域码LAC时GSM使用的是GsmCellLocation.getLac(),CDMA则用CdmaCellLocation.getNetworkId()来代替
在获取基站ID时GSM使用的是GsmCellLocation.getCid(),CDMA则用CdmaCellLocation.getBaseStationId()来代替
前面获取到的都是单个基站的信息，后面再获取周围邻近基站信息以辅助通过基站定位的精准性
TelephonyManager.getNeighboringCellInfo()，将其也放入基站信息LIST表中
最后通过google提供的gear接口获取经纬度，代码如下：
public static Location callGear(List<CellIDInfo> cellID) { if (cellID == null || cellID.size() == 0) return null; DefaultHttpClient client = new DefaultHttpClient(); HttpPost post = new HttpPost("http://www.google.com/loc/json"); JSONObject holder = new JSONObject(); try { holder.put("version", "1.1.0"); holder.put("host", "maps.google.com"); holder.put("home_mobile_country_code", cellID.get(0).mobileCountryCode); holder.put("home_mobile_network_code", cellID.get(0).mobileNetworkCode); holder.put("radio_type", cellID.get(0).radioType); holder.put("request_address", true); if ("460".equals(cellID.get(0).mobileCountryCode)) holder.put("address_language", "zh_CN"); else holder.put("address_language", "en_US"); JSONObject data,current_data; JSONArray array = new JSONArray(); current_data = new JSONObject(); current_data.put("cell_id", cellID.get(0).cellId); current_data.put("location_area_code", cellID.get(0).locationAreaCode); current_data.put("mobile_country_code", cellID.get(0).mobileCountryCode); current_data.put("mobile_network_code", cellID.get(0).mobileNetworkCode); current_data.put("age", 0); current_data.put("signal_strength", -60); current_data.put("timing_advance", 5555); array.put(current_data); if (cellID.size() > 2) { for (int i = 1; i < cellID.size(); i++) { data = new JSONObject(); data.put("cell_id", cellID.get(i).cellId); data.put("location_area_code", cellID.get(i).locationAreaCode); data.put("mobile_country_code", cellID.get(i).mobileCountryCode); data.put("mobile_network_code", cellID.get(i).mobileNetworkCode); data.put("age", 0); array.put(data); } } holder.put("cell_towers", array); StringEntity se = new StringEntity(holder.toString()); Log.e("Location send", holder.toString()); post.setEntity(se); HttpResponse resp = client.execute(post); HttpEntity entity = resp.getEntity(); BufferedReader br = new BufferedReader( new InputStreamReader(entity.getContent())); StringBuffer sb = new StringBuffer(); String result = br.readLine(); while (result != null) { Log.e("Locaiton reseive-->", result); sb.append(result); result = br.readLine(); } data = new JSONObject(sb.toString()); data = (JSONObject) data.get("location"); Location loc = new Location(LocationManager.NETWORK_PROVIDER); loc.setLatitude((Double) data.get("latitude")); loc.setLongitude((Double) data.get("longitude")); loc.setAccuracy(Float.parseFloat(data.get("accuracy").toString())); loc.setTime( System.currentTimeMillis());//AppUtil.getUTCTime()); return loc; } catch (JSONException e) { e.printStackTrace(); return null; } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return null; }
大家注意看这行holder.put("radio_type", cellID.get(0).radioType);
GSM就用"gsm",CDMA就用"cdma"
这个千万别搞混了，不然就获取不到信息了
