Android 双卡信号强度

Question

我一直在尝试使用我的 android 双卡 phone（品牌是 LKD）的一些功能。我已经设法通过 java 反射获得 TelephonyManager 和 ITelephony 的功能，并让它们运行。但是我想获得两张 SIM 卡的信号强度，但我看不到通过反射来做到这一点的方法。我可以通过具有 onSignalStrengthsChanged() 函数的 PhoneStateListener 获得插槽 1 中的第一张 SIM 卡。

有人对此有什么建议吗？我从反射中得到的函数：

上的 SIM 卡

谢谢！

Answer 1

对于这个特定版本的 TelephonyManager，而不是使用

TelephonyManager.listen (phoneStateListener, state)

只监听默认 SIM 卡，您可以尝试使用 PhoneStateListener 的 2 个实例，然后调用

TelephonyManager.listenGemini (phoneStateListener1, state, 0) 第一张 SIM 卡，

TelephonyManager.listenGemini (phoneStateListener2, state, 1) 对于第二张 SIM 卡，

其中 listenGemini 的第三个参数是 SIM 卡号码。

Answer 2

感谢您的回答headuck！我没有尝试过您的解决方案，但我发现我自己的解决方案有效。

可以为 TelephonyManager 使用不同的构造函数，您可以在其中传入要控制的 SIM 卡插槽：

    MultiSimClass = Class.forName("android.telephony.MultiSimTelephonyManager");

    for (Constructor<?> constructor : MultiSimClass.getConstructors()){
         if (constructor.getParameterTypes().length == 2){
              try {
                   multiSimTelephonyManager1 = constructor.newInstance(context,0);
                   multiSimTelephonyManager2 = constructor.newInstance(context,1);
             }
         }
     }

Answer 3

要获取两个 sim 卡的 sim 卡信号强度，我们必须使用电话管理器

telephonyManager = context.getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager?
            val cellInfos = telephonyManager?.allCellInfo as ArrayList
            val subManager = context.getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE) as SubscriptionManager?

这将给出单元格信息列表，我们需要获取注册的单元格信息

/* Function to get registered cell info
    *  @param cellinfo - all cell info for sim
    *  @return registered cell info correspond to cell info
    */
    fun getRegisteredCellInfo(cellInfos: MutableList<CellInfo>): ArrayList<CellInfo> {
        val registeredCellInfos = ArrayList<CellInfo>()
        if (cellInfos != null && cellInfos.isNotEmpty()) {
            for (i in cellInfos.indices) {
                if (cellInfos[i].isRegistered) {
                    registeredCellInfos.add(cellInfos[i])
                }
            }
        }
        return registeredCellInfos
    }

通过注册单元，您将获得设备中存在的 sim 信息列表现在通过我粘贴在下面的这段代码，您将根据您的网络类型获得信号强度，无论是 gsm、CDMA 还是 LTE。这也需要访问 phone 状态和粗略位置的运行时权限，因此请相应地添加它们，注册的单元信息索引是设备中存在的 sim 1 和 sim 2 的索引。 Sim 1 是 0 索引，sim 2 是 1 索引，你必须通过。

(registeredCellInfos.get(registeredCellInfoIndex) is CellInfoWcdma) -> {
                        val cellInfoWcdma = registeredCellInfos.get(registeredCellInfoIndex) as CellInfoWcdma
                        signalStrength = "${cellInfoWcdma.cellSignalStrength.dbm}"
                    }
                    (registeredCellInfos.get(registeredCellInfoIndex) is CellInfoGsm) -> {
                        val cellInfogsm = registeredCellInfos.get(registeredCellInfoIndex) as CellInfoGsm
                        signalStrength = "${cellInfogsm.cellSignalStrength.dbm}"
                    }
                    (registeredCellInfos.get(registeredCellInfoIndex) is CellInfoLte) -> {
                        val cellInfoLte = registeredCellInfos.get(registeredCellInfoIndex) as CellInfoLte
                        signalStrength = "${cellInfoLte.cellSignalStrength.dbm}"
                    }

Answer 4

这里是解决方案科特林注意：Android Pie 及以上信号只有在 location 开启时才会获取，为什么我不知道

    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
}

    var strength2 = -1

        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]) {
