編輯:Android開發實例
基站定位原理:通過手機信號獲取基站信息,然後調用第三方公開的根據基站信息查找基站的經緯度值及地址信息(大概位置)。
一、通過手機信號獲取基站信息(詳細的可以參考: Android基站定位之實現通過手機信號獲取基站信息 )
- TelephonyManager mTelephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
- // 返回值MCC + MNC
- String operator = mTelephonyManager.getNetworkOperator();
- mcc = Integer.parseInt(operator.substring(0, 3));
- mnc = Integer.parseInt(operator.substring(3));
- // 中國移動和中國聯通獲取LAC、CID的方式
- GsmCellLocation location = (GsmCellLocation) mTelephonyManager.getCellLocation();
- lac = location.getLac();
- cid = location.getCid();
- Log.i(TAG, "MCC = " + mcc + "\t MNC = " + mnc + "\t LAC = " + lac + "\t CID = " + cid);
二、調用第三方公開的API(根據基站信息查找基站的經緯度值及地址信息)
1、組拼JSON形式的請求參數
- /**
- * 獲取JSON形式的基站信息
- * @param mcc 移動國家代碼(中國的為460)
- * @param mnc 移動網絡號碼(中國移動為0,中國聯通為1,中國電信為2);
- * @param lac 位置區域碼
- * @param cid 基站編號
- * @return json
- * @throws JSONException
- */
- private String getJsonCellPos(int mcc, int mnc, int lac, int cid) throws JSONException {
- JSONObject jsonCellPos = new JSONObject();
- jsonCellPos.put("version", "1.1.0");
- jsonCellPos.put("host", "maps.google.com");
- JSONArray array = new JSONArray();
- JSONObject json1 = new JSONObject();
- json1.put("location_area_code", "" + lac + "");
- json1.put("mobile_country_code", "" + mcc + "");
- json1.put("mobile_network_code", "" + mnc + "");
- json1.put("age", 0);
- json1.put("cell_id", "" + cid + "");
- array.put(json1);
- jsonCellPos.put("cell_towers", array);
- return jsonCellPos.toString();
- }
2、通過HTTP協議網絡請求源碼:
- request URL:http://www.minigps.net/minigps/map/google/location
- Request Method:POST
- Status Code:200 OK
- Request Headersview source
- Accept:application/json, text/javascript, */*; q=0.01
- Accept-Charset:GBK,utf-8;q=0.7,*;q=0.3
- Accept-Encoding:gzip,deflate,sdch
- Accept-Language:zh-CN,zh;q=0.8
- Connection:keep-alive
- Content-Length:191
- Content-Type:application/json; charset=UTF-8
- Cookie:bdshare_firstime=1356366713546; JSESSIONID=68243935CD3355089CF07A3A22AAB372
- Host:www.minigps.net
- Origin:http://www.minigps.net
- Referer:http://www.minigps.net/map.html
- User-Agent:Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.94 Safari/537.4
- X-Requested-With:XMLHttpRequest
- Request Payload
- {"cell_towers":[{"mobile_network_code":"1","location_area_code":"43018","cell_id":"11152773","age":0,"mobile_country_code":"460"}],"host":"maps.google.com","version":"1.1.0"}
- Response Headersview source
- Content-Type:application/json
- Date:Sat, 03 Jan 2013 14:03:15 GMT
- Server:Apache-Coyote/1.1
- Transfer-Encoding:chunked
3、用JAVA代碼具體實現:
- /**
- * 調用第三方公開的API根據基站信息查找基站的經緯度值及地址信息
- */
- public String httpPost(String url, String jsonCellPos) throws IOException{
- byte[] data = jsonCellPos.toString().getBytes();
- URL realUrl = new URL(url);
- HttpURLConnection httpURLConnection = (HttpURLConnection) realUrl.openConnection();
- httpURLConnection.setConnectTimeout(6 * 1000);
- httpURLConnection.setDoOutput(true);
- httpURLConnection.setDoInput(true);
- httpURLConnection.setUseCaches(false);
- httpURLConnection.setRequestMethod("POST");
- httpURLConnection.setRequestProperty("Accept", "application/json, text/javascript, */*; q=0.01");
- httpURLConnection.setRequestProperty("Accept-Charset", "GBK,utf-8;q=0.7,*;q=0.3");
- httpURLConnection.setRequestProperty("Accept-Encoding", "gzip,deflate,sdch");
- httpURLConnection.setRequestProperty("Accept-Language", "zh-CN,zh;q=0.8");
- httpURLConnection.setRequestProperty("Connection", "Keep-Alive");
- httpURLConnection.setRequestProperty("Content-Length", String.valueOf(data.length));
- httpURLConnection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
- httpURLConnection.setRequestProperty("Host", "www.minigps.net");
- httpURLConnection.setRequestProperty("Referer", "http://www.minigps.net/map.html");
- httpURLConnection.setRequestProperty("User-Agent",
- "Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.94 Safari/537.4X-Requested-With:XMLHttpRequest");
- httpURLConnection.setRequestProperty("X-Requested-With", "XMLHttpRequest");
- httpURLConnection.setRequestProperty("Host", "www.minigps.net");
- DataOutputStream outStream = new DataOutputStream(httpURLConnection.getOutputStream());
- outStream.write(data);
- outStream.flush();
- outStream.close();
- if (httpURLConnection.getResponseCode() == HttpURLConnection.HTTP_OK) {
- InputStream inputStream = httpURLConnection.getInputStream();
- return new String(read(inputStream));
- }
- return null;
- }
4、讀取返回的JSON數據流代碼:
- /**
- * 讀取IO流並以byte[]形式存儲
- * @param inputSream InputStream
- * @return byte[]
- * @throws IOException
- */
- public byte[] read(InputStream inputSream) throws IOException {
- ByteArrayOutputStream outStream = new ByteArrayOutputStream();
- int len = -1;
- byte[] buffer = new byte[1024];
- while ((len = inputSream.read(buffer)) != -1) {
- outStream.write(buffer, 0, len);
- }
- outStream.close();
- inputSream.close();
- return outStream.toByteArray();
- }
三、請求參數及返回結果的JSON形式:
1、請求的JSON參數值:
- {
- "cell_towers":
- [
- {
- "mobile_network_code":"1",
- "location_area_code":"43018",
- "cell_id":"11152773",
- "age":0,
- "mobile_country_code":"460"
- }
- ],
- "host":"maps.google.com",
- "version":"1.1.0"
- }
2、返回的JSON結果值:
- {
- "location":
- {
- "latitude":"31.211389541625977",
- "longitude":"121.60332489013672",
- "address":
- {"city":
- "上海市浦東新區居裡路432號;浦東新區光啟安老院、第一三共制藥上海公司、SUNPLUS[附近]",
- "country":"",
- "country_code":"",
- "county":"",
- "postal_code":"",
- "region":"",
- "street":"",
- "street_number":""
- }
- },
- "access_token":"dummytoken"
- }

- <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
- <uses-permission android:name="android.permission.INTERNET" />
