在Android studio中，分别显示物理机两张卡所属运营商以及所用网络和网络信号强度

要显示物理机两张卡所属运营商以及所用网络和网络信号强度，需要使用TelephonyManager类和SignalStrength类。以下是代码示例：

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

// 获取SIM卡1信息
int simState1 = telephonyManager.getSimState(0);
if (simState1 == TelephonyManager.SIM_STATE_READY) {
    // 获取运营商名称
    String operator1 = telephonyManager.getSimOperatorName(0);
    // 获取网络类型
    String networkType1 = getNetworkType(telephonyManager.getNetworkType(0));
    // 获取信号强度
    int signalStrength1 = getSignalStrength(telephonyManager.getSignalStrength(0));
    Log.d("SIM1", "Operator: " + operator1 + ", Network Type: " + networkType1 + ", Signal Strength: " + signalStrength1);
}

// 获取SIM卡2信息
int simState2 = telephonyManager.getSimState(1);
if (simState2 == TelephonyManager.SIM_STATE_READY) {
    // 获取运营商名称
    String operator2 = telephonyManager.getSimOperatorName(1);
    // 获取网络类型
    String networkType2 = getNetworkType(telephonyManager.getNetworkType(1));
    // 获取信号强度
    int signalStrength2 = getSignalStrength(telephonyManager.getSignalStrength(1));
    Log.d("SIM2", "Operator: " + operator2 + ", Network Type: " + networkType2 + ", Signal Strength: " + signalStrength2);
}

// 网络类型转换
private String getNetworkType(int networkType) {
    switch (networkType) {
        case TelephonyManager.NETWORK_TYPE_GPRS:
            return "GPRS";
        case TelephonyManager.NETWORK_TYPE_EDGE:
            return "EDGE";
        case TelephonyManager.NETWORK_TYPE_UMTS:
            return "UMTS";
        case TelephonyManager.NETWORK_TYPE_HSDPA:
            return "HSDPA";
        case TelephonyManager.NETWORK_TYPE_HSUPA:
            return "HSUPA";
        case TelephonyManager.NETWORK_TYPE_HSPA:
            return "HSPA";
        case TelephonyManager.NETWORK_TYPE_CDMA:
            return "CDMA";
        case TelephonyManager.NETWORK_TYPE_EVDO_0:
            return "EVDO_0";
        case TelephonyManager.NETWORK_TYPE_EVDO_A:
            return "EVDO_A";
        case TelephonyManager.NETWORK_TYPE_EVDO_B:
            return "EVDO_B";
        case TelephonyManager.NETWORK_TYPE_LTE:
            return "LTE";
        default:
            return "Unknown";
    }
}

// 信号强度转换
private int getSignalStrength(SignalStrength signalStrength) {
    if (signalStrength == null) {
        return 0;
    } else {
        int level = signalStrength.getLevel();
        switch (level) {
            case 0:
                return -113;
            case 1:
                return -87;
            case 2:
                return -75;
            case 3:
                return -67;
            case 4:
                return -51;
            default:
                return 0;
        }
    }
}

在上面的代码中，我们首先使用TelephonyManager类获取物理机的SIM卡状态和信息。然后，我们使用getNetworkType()和getSignalStrength()方法将网络类型和信号强度转换为易于理解的字符串和整数。最后，我们使用Log.d()方法将结果打印到控制台。请注意，getSignalStrength()方法返回的是整数，表示信号强度的负值，例如“-87”表示信号强度为“-87dBm”。
