通過經緯度擷取城市名/地址(不需要三方包)，經緯度三方

通過經緯度擷取城市名/地址(不需要三方包)，經緯度三方

1:getLocation()方法篩選出最優擷取經緯度的方法

2:MapThread線程通過將getLocation()擷取的經緯度上傳而擷取城市名

public class PositionActivity extends BaseActivity implements IInit, IResponseHandler, View.OnClickListener {    private TextView mLocationTV, mCategoryTV;//位置.種類    private double latitude, longitude;//經緯度    private String mapUriStr = "http://maps.google.cn/maps/api/geocode/json?latlng={0},{1}&sensor=true&language=zh-CN";    private HttpResponse httpResponse = null;    private HttpEntity httpEntity = null;    private MapThread mapThread;    private Handler handler;    private String result;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_share_goods_edit);        init();    }    @Override    public void init() {        mLocationTV = (TextView) findViewById(R.id.tv_goods_location);,        getLocation();//擷取經緯度        mapThread = new MapThread();        mapThread.start();    }    //擷取經緯度    public void getLocation() {        LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);        List<String> lp = lm.getAllProviders();// 返回所有已知的位置提供者的名稱列表，包括未獲准訪問或調用活動目前已停用的。        for (String item : lp) {//            Log.i("---->可用位置服務:", item);        }        Criteria criteria = new Criteria();        criteria.setCostAllowed(false);//設定位置服務免費        criteria.setAccuracy(Criteria.ACCURACY_COARSE); //設定水平位置精度        String providerName = lm.getBestProvider(criteria, true); //getBestProvider 只有允許訪問調用活動的位置供應商將被返回        if (providerName != null) {            Location location = lm.getLastKnownLocation(providerName);            latitude = location.getLatitude();//擷取維度資訊            longitude = location.getLongitude();//擷取經度資訊        } else {            ToastUtil.show(this, "1.請檢查網路連接 \n2.請開啟我的位置");        }    }    class MapThread extends Thread {        @Override        public void run() {            super.run();            String uriStr = MessageFormat.format(mapUriStr, latitude, longitude);            HttpGet httpGet = new HttpGet(uriStr);//產生一個請求對象            HttpClient httpClient = new DefaultHttpClient(); //產生一個Http用戶端對象            try {                httpResponse = httpClient.execute(httpGet); //使用Http用戶端發送請求對象                httpEntity = httpResponse.getEntity(); //擷取響應內容                BufferedReader reader = new BufferedReader(new InputStreamReader(httpEntity.getContent()));                result = "";                String line = "";                while ((line = reader.readLine()) != null) {                    result += line;                }Log.v("地址:",result );            } catch (Exception e) {                e.printStackTrace();            }        }    }}
