Question

我想以编程方式在Android上获取所有附近的移动运营商及其信号强度使用PhoneStateListener，我能够获得我当前注册的运营商的信号强度，但我找不到找到附近其他运营商信号强度的方法。
我怎样才能做到这一点？

Answer 1

Use this for getting cellular carrier name

// Get System TELEPHONY service reference
TelephonyManager telephonyManager = (TelephonyManager) getBaseContext()
      .getSystemService(Context.TELEPHONY_SERVICE);

// Get carrier name (Network Operator Name)
String carrierName = telephonyManager.getNetworkOperatorName();

For getting Signal Strength


TelephonyManager telephonyManager = (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);`

CellInfoGsm cellinfogsm = (CellInfoGsm)telephonyManager.getAllCellInfo().get(0);

CellSignalStrengthGsm cellSignalStrengthGsm = cellinfogsm.getCellSignalStrength();

cellSignalStrengthGsm.getDbm();

希望它可以帮到你
