安卓双卡信号强度问题

androidtelephonymanagersignal-strengthdual-sim
7
我一直在尝试获取我的安卓双卡手机（品牌为LKD）的某些功能。我通过Java反射获得了TelephonyManager和ITelephony的函数，并且让它们运行起来了。然而，我想获取两张SIM卡的信号强度，但是我无法通过反射找到方法。我可以通过设置一个PhoneStateListener并使用onSignalStrengthsChanged()函数来获取第一张插在插槽1中的SIM卡的信号强度。

有人有什么建议吗？以下是我从反射中获取的函数：

感谢headuck的回答！我还没有尝试过你的解决方案，但我找到了自己的解决方案，它有效。

可以使用TelephonyManager的不同构造函数，您可以在其中传递要控制的sim卡槽：

    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);
             }
         }
     }
你好 Roger，你使用上面的代码片段获取了双卡手机的 SIM 详细信息吗？MultiSimClass、multiSimTelephonyManager1 和 multiSimTelephonyManager2 的类型是什么？ - Quick learner
1
你好！上面的代码片段只给出了MultiSimTelephonyManager类的构造函数列表。要获取其他方法，您可以执行以下操作：for (Method method : MultiSimClass.getMethods()){ System.out.println("method name: " + method.getName()); }要获取方法中参数类型的列表，您可以执行method.getParameterTypes()或getReturnType()以获取方法的返回类型。MultiSimClass是Class类型，multiSimTelephonyManager是Object类型。 - dag roger stokland rui
你有尝试在任何安卓双卡手机上获取双卡槽/运营商名称/IMSI/MSISDN吗？ - Quick learner
是的，这是在安卓手机上。我还没有尝试获取IMSI/MSISDN。 - dag roger stokland rui
你好。你如何监听对象（multiSimTelephonyManager1）的信号强度，该对象不提供任何方法？你需要将TelephonyManager类型转换为它吗？ - Android
1
Method listenMethod = MultiSimClass.getMethod("listen");listenMethod.invoke(multiSimTelephonyManager1, new PhoneStateListener(), PhoneStateListener.LISTEN_SIGNAL_STRENGTHS); - dag roger stokland rui
2
对于这个特定版本的TelephonyManager，不要使用只监听默认SIM卡的TelephonyManager.listen（phoneStateListener，state），而是可以尝试使用两个PhoneStateListener实例，并调用TelephonyManager.listenGemini（phoneStateListener1，state，0）来监听第一个SIM卡，以及TelephonyManager.listenGemini（phoneStateListener2，state，1）来监听第二个SIM卡，其中listenGemini的第三个参数是SIM卡号。请注意保留HTML标签。

“listenGemini” 是从哪里来的？ - danijax
“listenGemini”是设备TelephonyManager的特定实现中的内部方法名称，以支持双卡手机-请参阅通过reflection获得的问题的方法列表。这种接口在2017年应该已经大部分过时，因为现代Android原生支持双卡。 - headuck

要获取两张SIM卡的信号强度，我们需要使用电话管理器。

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

现在这将给出单元信息列表，我们需要获取已注册的单元信息。

/* 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，通过下面我粘贴的代码，您将根据网络类型（无论是gsm、CDMA还是LTE）获得信号强度。这也需要运行时许可访问手机状态和粗略位置，因此请相应地添加它们，并且已注册的单元信息索引是设备中存在的sim卡一和sim卡二的索引。Sim卡1为0索引，Sim卡2为1索引，您需要传递。

(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}"
                    }

这里是解决方案 Kotlin 注意：Android Pie及以上版本只有在位置开启的情况下才会获取信号，原因我不知道

    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
}


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]) {
