如何使用Kotlin获得双SIM卡信号强度

2024-05-04 • 问答

使用电话状态监听器，我正在获取默认的SIM信号强度，如何确定第二个SIM信号强度。请帮助我找出这个问题

我也使用了Telemetry manager，但我没有获得第二模拟信号强度

val phonestateListener: PhonestateListener = object : PhonestateListener() {
    override fun onServiceStateChanged(serviceState: ServiceState) {
        Timber.d("Current cell state : ${serviceState.state}")
        }

    override fun onSignalStrengthsChanged(signalStrength: SignalStrength) 
        {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            Timber.d("Current cell signal: ${signalStrength.level}")
               } else {
      Timber.d("Current cell signal:${signalStrength.gsmSignalStrength}")
        }
    }
}


telephonyManager = getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager
telephonyManager.listen(phonestateListener,PhonestateListener.LISTEN_SERVICE_STATE or PhonestateListener.LISTEN_SIGNAL_STRENGTHS)

以上问题我都得到了解决方案

        fun getRegisteredCellInfo(cellInfos: MutableList<CellInfo>): ArrayList<CellInfo> {
    val registeredCellInfos = ArrayList<CellInfo>()
    if (cellInfos.isNotEmpty()) {
        for (i in cellInfos.indices) {
            if (cellInfos[i].isRegistered) {
                registeredCellInfos.add(cellInfos[i])
            }
        }
    }
    return registeredCellInfos
}



fun getNetworkStrength(): Pair<Int,Int> {

    var strength1 = -1
    var strength2 = -1


    val manager = getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE) as SubscriptionManager


    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {

        val telephonyManager = applicationContext.getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager


        if (telephonyManager.allCellInfo != null) {


            val allCellinfo = telephonyManager.allCellInfo
            val activeSubscriptionInfoList = manager.activeSubscriptionInfoList

           val regCellInfo= getRegisteredCellInfo(allCellinfo)

                activeSubscriptionInfoList.forEachIndexed { Subindex,subs ->

                    if (activeSubscriptionInfoList.size >= 2) {

                        if (regCellInfo.size >= 2) {

                            if (subs.simSlotIndex == 0) {

                                if (subs.carrierName != "No service") {


                                    strength1 = when (val info1 = regCellInfo[0]) {
