CDMA:

用下面方法取得CDMA信号强度只是-1,请哪位高手请指点一下,谢了 mSignalStrength = new SignalStrength();

int cdmaDbm = mSignalStrength.getCdmaDbm(); int cdmaEcio = mSignalStrength.getCdmaEcio(); android 获取手机GSM/CDMA信号信息

在Android中我们常用的轻松获取WIFI信号列表，那如何获取CDMA或者GSM的手机信号呢？

系统提供了TelephonyManager类，此类非常丰富，基本你所需要的手机信息都能获取到，那下面就来看看我们所需要的CDMA与GSM信号是如何获取的吧。

private TelephonyManager telephonyManager; private PhoneStateListener phoneStateListener; 首先声明两个变量

在onCreate()方法中初始化变量 InitPhoneStateListener();

telephonyManager = (TelephonyManager) this.ctx.getSystemService(Context.TELEPHONY_SERVICE); telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_SIGNAL_STRENGTHS); telephonyManager.listen(phoneStateListener,PhoneStateListener.LISTEN_CELL_LOCATION); if(telephonyManager.getCellLocation()!=null){

//获取当前基站信息

phoneStateListener.onCellLocationChanged(telephonyManager.getCellLocation()); }

/** 初始化PhoneStateListener */ private void InitPhoneStateListener() {

phoneStateListener = new PhoneStateListener() { @Override

public void onCellLocationChanged(CellLocation location) { // TODO Auto-generated method stub

if (location instanceof GsmCellLocation) {// gsm网络 phoneType = 1;

GsmCell gsmCell = new GsmCell();

gsmCell.lac = ((GsmCellLocation) location).getLac(); gsmCell.cid = ((GsmCellLocation) location).getCid(); /** 获取mcc，mnc */

String mccMnc=telephonyManager.getNetworkOperator(); if(mccMnc!=null&&mccMnc.length()>=5){ gsmCell.mcc = mccMnc.substring(0, 3); gsmCell.mnc = mccMnc.substring(3, 5); }

gsmCell.signal=lastSignal;

gsmCell.time = System.currentTimeMillis(); if (gsmCell.lac != -1 && gsmCell.cid != -1) { gsmCells.add(0, gsmCell); // Collections.sort(gsmCells); // /**最多保存近3个基站信息*/ // if (gsmCells.size() >3) // gsmCells.remove(3); }

//获取相邻基站信息

List neighboringList=telephonyManager.getNeighboringCellInfo(); for(NeighboringCellInfo ni:neighboringList){ GsmCell gb = new GsmCell(); gb.mnc=mccMnc.substring(3, 5); gb.lac=ni.getLac(); gb.cid=ni.getCid();

gb.signal=-133+2*ni.getRssi();

gb.time=System.currentTimeMillis(); gsmCells.add(gb); }

} else {// 其他CDMA等网络 try {

Class cdmaClass = Class.forName(\phoneType = 2;

CdmaCellLocation cdma = (CdmaCellLocation) location; CdmaCell cdmaCell = new CdmaCell();

cdmaCell.stationId = cdma.getBaseStationId() >= 0 ? cdma.getBaseStationId(): cdmaCell.stationId; cdmaCell.networkId = cdma.getNetworkId() >= 0 ? cdma .getNetworkId() : cdmaCell.networkId;

cdmaCell.systemId = cdma.getSystemId() >= 0 ? cdma .getSystemId() : cdmaCell.systemId; /** 获取mcc，mnc */

String mccMnc=telephonyManager.getNetworkOperator(); if(mccMnc!=null&&mccMnc.length()>=5){ cdmaCell.mcc = mccMnc.substring(0, 3); cdmaCell.mnc = mccMnc.substring(3, 5); }

cdmaCell.signal=lastSignal;

cdmaCell.time = System.currentTimeMillis(); int lat = cdma.getBaseStationLatitude(); int lon = cdma.getBaseStationLongitude();

if (lat

if (cdmaCell.stationId != -1&& cdmaCell.networkId != -1&& cdmaCell.systemId != -1) { cdmaCells.add(0, cdmaCell); }

List neighboringList=telephonyManager.getNeighboringCellInfo(); for(NeighboringCellInfo ni:neighboringList){ CdmaCell cdmaBean = new CdmaCell(); cdmaBean.systemId=cdmaCell.systemId; cdmaBean.lac=ni.getLac(); cdmaBean.cellid=ni.getCid();
