Question

android怎么获取用户所在地 csdn

Answer 1

三种方式进行定位，获取用户位置，分别是基于基站定位， 网络定位，GPS定位。

1.基站定位(passive)：这是基于网络基站进行定位的，定位的精确度在几十米到几千米不等，在城市中基站覆盖率比较高，推荐使用基站定位，如果是在郊区，基站相距较远，基站的覆盖没有城里好，定位的误差比较大。如果在郊区不推荐使用基站定位。

2.网络定位：wifi定位，网络定位

3.GPS定位：与卫星进行通信。手机中嵌入了GPS模块(精简版的A-GPS)，通过A-GPS搜索卫星， 获取经纬度。使用GPS的弊端是:必须站在空旷的地方，头顶对着天空，如果云层厚了，也会受到一定的影响。精确度:10-50米

扩展知识：

使用Android是定位必备的权限：
< uses-permission android:name= " android.permission.ACCESS_FINE_LOCATION " />      //精确定位
<uses-permission android:name= "android.permission.ACCESS_MOCK_LOCATION" />      //模拟器
<uses-permission android:name= "android.permission.ACCESS_COARSE_LOCATION" />   //粗糙定位
 
//获取定位管理对象
LocationManager  lm=(LocationManager)getSystemService(LOCATION_SERVICE);
String[] names=lm.getAllProviders();//获取所有的位置提供者，一般三种

Criteria  criteria=new Criteria();//查询条件，如果设置了海拔，则定位方式只能是GPS;
criteria.setCostAllowed(true);//是否产生开销，比如流量费
String provider=lm.getBaseProvider(criteria,true)//获取最好的位置提供者，第二个参数为true，表示只获取那些被打开的位置提供者

lm.requestLocationUpdates(provier,0,0,new LocationListener(){});//获取位置。第二个参数表示每隔多少时间返回一次数据，第三个参数表示被定位的物体移动每次多少米返回一次数据。

private class MyLocationListener implements LocationListener {
            @Override
            public void onStatusChanged(String provider, int status, Bundle extras) {

           }

            @Override
            public void onProviderEnabled(String provider) {

           }

            @Override
         


            @Override
            public void onLocationChanged(Location location) {
                 System. out.println( "服务中位置监听发送了变化了" );
                  float accuracy = location.getAccuracy(); // 精确度
                  double altitude = location.getAltitude(); // 海拔
                  double latitude = location.getLatitude(); // 纬度
                  double longitude = location.getLongitude(); // 经度
                 String locationInfo = "jingdu:" + longitude + ",weidu:" + latitude + ",haiba:" + altitude + ",jingquedu:" + accuracy;
                 Editor edit = sp.edit();
                 edit.putString( "location", locationInfo);
                 edit.commit();
           }
     }   public void onProviderDisabled(String provider) {

           }

Answer 2

在很多生活类工具应用中都会包含用户位置信息，这样更方便的为用户服务。 经常我们使用三种方式进行定位，获取用户位置，分别是基于基站定位， 网络定位，GPS定位。

一：基站定位(passive)：这是基于网络基站进行定位的，定位的精确度在几十米到几千米不等，在城市中基站覆盖率比较高，推荐使用基站定位，如果是在郊区，基站相距较远，基站的覆盖没有城里好，定位的误差比较大。如果在郊区不推荐使用基站定位。

二：网络定位：wifi定位，网络定位
运营商下放IP地址。比如彩虹QQ。
google纵横（统计一个非常大的IP和地址映射关系）
动态IP（IP池中随机获取一个IP地址，每次联网都会去池中获取一个随机的IP ，得到的是一个大体的地址），比如新浪微博。天气定位

方式三:GPS定位
与卫星进行通信。
手机中嵌入了GPS模块(精简版的A-GPS)，通过A-GPS搜索卫星， 获取经纬度。
使用GPS的弊端是:必须站在空旷的地方，头顶对着天空，如果云层厚了，也会受到一定的影响。
精确度:10-50米

float accuracy = location.getAccuracy(); // 精确度

最近在做一个互联网项目，不可避免和其他互联网项目一样，需要各种类似的功能。其中一个就是通过用户访问网站的IP地址显示当前用户所在地。在没有查阅资料之前，我第一个想到的是应该有这样的RESTFUL服务，可能会有免费的，也有可能会是收费的。后来查阅了相关资料和咨询了客服人员发现了一款相当不错的库：GEOIP。

这个好像手机没有这个功能吧，最多就是通过软件定位....
