1:getLocation()方法筛选出最优获取经纬度的方法

2:MapThread线程通过将getLocation()获取的经纬度上传而获取城市名

public class PositionActivity extends BaseActivity implements IInit, IResponseHandler, View.OnClickListener {
    private TextView mLocationTV, mCategoryTV;//位置.种类
    private double latitude, longitude;//经纬度
    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();//获取经纬度
        mapThread = new MapThread();
        mapThread.start();

    }

    //获取经纬度
    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称列表，包括未获准访问或调用活动目前已停用的。
        for (String item : lp) {
//            Log.i("---->可用位置服务:", item);
        }

        Criteria criteria = new Criteria();
        criteria.setCostAllowed(false);//设置位置服务免费
        criteria.setAccuracy(Criteria.ACCURACY_COARSE); //设置水平位置精度
        String providerName = lm.getBestProvider(criteria, true); //getBestProvider 只有允许访问调用活动的位置供应商将被返回

        if (providerName != null) {
            Location location = lm.getLastKnownLocation(providerName);
            latitude = location.getLatitude();//获取维度信息
            longitude = location.getLongitude();//获取经度信息
        } else {
            ToastUtil.show(this, "1.请检查网络连接 \n2.请打开我的位置");
        }
    }


    class MapThread extends Thread {
        @Override
        public void run() {
            super.run();
            String uriStr = MessageFormat.format(mapUriStr, latitude, longitude);
            HttpGet httpGet = new HttpGet(uriStr);//生成一个请求对象
            HttpClient httpClient = new DefaultHttpClient(); //生成一个Http客户端对象

            try {
                httpResponse = httpClient.execute(httpGet); //使用Http客户端发送请求对象
                httpEntity = httpResponse.getEntity(); //获取响应内容
                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();
            }

        }
    }

}

通过经纬度获取城市名/地址(不需要三方包)
