文章标签： android 如何获取信号强度

本文档展示了如何在Android MainActivity中获取手机运营商信息、信号强度及邻区基站信息，包括MCC、MNC、LAC和CellID。重点介绍了使用TelephonyManager监听信号强度变化和CellLocation获取位置信息的方法。

24 int lac =location.getLac();25 int cellid =location.getCid();26 System.out.println("**"+mcc+"A"+mnc+"A"+lac+"A"+cellid);27 textView1.setText("国家编号："+mcc+"运营商编号："+mnc+"LAC："+lac+"CellID："+cellid);28 List infos =telephonyManager.getAllCellInfo();29 //List infos = telephonyManager.getNeighboringCellInfo();

30 StringBuffer sb = new StringBuffer("总数 : " + infos.size() + "\n");31 for (CellInfo info1 : infos) { //根据邻区总数进行循环32 //sb.append(" LAC : " + info1.getLac());//取出当前邻区的LAC33 //sb.append(" CID : " + info1.getCid());//取出当前邻区的CID

34 sb.append(" CID : " + info1.toString()); //取出当前邻区的CID35 //sb.append(" BSSS : " + (-113 + 2 * info1.getRssi()) + "\n");//获取邻区基站信号强度
