Rexsee API介绍：基站定位功能，Android CellLocation源码

分类： 虚拟化

2012-03-20 20:57:19

先提示一点，不能使用用模拟器研究Android的基站定位：基站信息是来自运营商的，仿真器只能模拟网络延迟（-netdelay）、网速（-netspeed）、以及一些电话相关的操作，gsm 。还不能模拟信号。

一段基于Rexsee（）的基本示例demo，其中cid 和 lac 为经纬度。

Html代码 复制代码 收藏代码
  1. function query(){
  2. var loction = eval('('+rexseeCellLocation.getLastKnownLocation()+')');
  3. var type = location.type.toLowerCase();
  4. var mcc = parseInt(location.operator.substring(0,3));
  5. var mnc = (type=='gsm')?parseInt(location.operator.substring(3)):location.systemId;
  6. var cid= (type=='gsm')?location.cid:location.baseStationId;
  7. var lac= (type=='gsm')?location.lac:location.networkId;
  8. var postData="{\version\":\"1.1.0\",\"host\":\maps.google.com\",\"access_token\";\"2:k7j3G6LaL6u_lafw:4iXOeOpTh1glSXe\",\"home_mobile_country_code\":"+mcc+",\"home_mobile_network_code\":"+mnc+",\"address_language\";\"zh_CN\",\"radio_type\";\""+type+"\",\"request_address\":true,\"cell_towers\":[{\"cell_id\":+cid+",\"location_area_code\":+lac+",\"mobile_aountry_code\":"+mcc+",\"mobile_network_code\":"+mnc+",\"timing_advance\":5555}]}";
  10. alert(rexseeAjax.syncSubmit('',postData,'utf-8'));
  11. }
function query(){ var loction = eval('('+rexseeCellLocation.getLastKnownLocation()+')'); var type = location.type.toLowerCase(); var mcc = parseInt(location.operator.substring(0,3)); var mnc = (type=='gsm')?parseInt(location.operator.substring(3)):location.systemId; var cid= (type=='gsm')?location.cid:location.baseStationId; var lac= (type=='gsm')?location.lac:location.networkId; var postData="{\version\":\"1.1.0\",\"host\":\maps.google.com\",\"access_token\";\"2:k7j3G6LaL6u_lafw:4iXOeOpTh1glSXe\",\"home_mobile_country_code\":"+mcc+",\"home_mobile_network_code\":"+mnc+",\"address_language\";\"zh_CN\",\"radio_type\";\""+type+"\",\"request_address\":true,\"cell_towers\":[{\"cell_id\":+cid+",\"location_area_code\":+lac+",\"mobile_aountry_code\":"+mcc+",\"mobile_network_code\":"+mnc+",\"timing_advance\":5555}]}"; alert(rexseeAjax.syncSubmit('',postData,'utf-8')); }

返回的结果是：

需要注意几个问题：

1. 如果直接用alert(rexseeCellLocation.getLastKnownLocation()); 这个方法得到的经纬度会是两个非常大的数字 所以需要通过ajax提交到"" 把所需要的经纬度返回来；

2. 开始监听，一旦位置发生变化，会触发事件onCellLocationChanged。所以，要在 onCellLocationChanged中写代码，调用你的query函数。而不是直接使用onclick测试。

Rexsee扩展函数介绍
