Android编程实现WIFI定位

WIFI定位其实和基站定位都差不多，只需要把WIFI的MAC地址取到传给google就行了，下面是具体实现！

04.import android.net.wifi.WifiManager;

05.import android.util.Log;

16.private static final long serialVersionUID = -4582739827003032383L;

18.private Context context;

19. 

20.public WiFiInfoManager(Context context) {

21.super();

22.this.context = context;

23.}

24. 

25.public WifiInfo getWifiInfo() {

26.WifiManager manager = (WifiManager) context

27..getSystemService(Context.WIFI_SERVICE);

28.WifiInfo info = new WifiInfo();

29.info.mac = manager.getConnectionInfo().getBSSID();

30.Log.i("TAG", "WIFI MAC is:" + info.mac);

31.return info;

32.}

33. 

34.public class WifiInfo {

35. 

36.public String mac;

37. 

38.public WifiInfo() {

39.super();

40.}

41.}

42. 

43.}

上面是取到WIFI的mac地址的方法，下面是把地址发送给google服务器,代码如下：

01.public static Location getWIFILocation(WifiInfo wifi) {

02.if (wifi == null) {

06.DefaultHttpClient client = new DefaultHttpClient();

07.HttpPost post = new HttpPost("http://www.google.com/loc/json");

14.JSONArray array = new JSONArray();

15.if (wifi.mac != null && wifi.mac.trim().length() > 0) {

16.data = new JSONObject();

17.data.put("mac_address", wifi.mac);

18.data.put("signal_strength", 8);

27.int state = resp.getStatusLine().getStatusCode();

28.if (state == HttpStatus.SC_OK) {

29.HttpEntity entity = resp.getEntity();

30.if (entity != null) {

31.BufferedReader br = new BufferedReader(

32.new InputStreamReader(entity.getContent()));

33.StringBuffer sb = new StringBuffer();

34.String resute = "";

35.while ((resute = br.readLine()) != null) {

36.sb.append(resute);

37.}

38.br.close();

39. 

40.Log.i("TAG", "response json:" + sb.toString());

41.data = new JSONObject(sb.toString());

42.data = (JSONObject) data.get("location");

43. 

44.Location loc = new Location(

45.android.location.LocationManager.NETWORK_PROVIDER);

46.loc.setLatitude((Double) data.get("latitude"));

47.loc.setLongitude((Double) data.get("longitude"));

48.loc.setAccuracy(Float.parseFloat(data.get("accuracy")

49..toString()));

50.loc.setTime(System.currentTimeMillis());

51.return loc;

52.} else {

53.return null;

54.}

55.} else {

56.Log.v("TAG", state + "");

57.return null;

58.}

59. 

60.} catch (Exception e) {

61.Log.e("TAG", e.getMessage());

62.return null;
