您可以尝试在BroadcastReceiver类中执行此操作，

public class IncomingCallInterceptor extends BroadcastReceiver {
     @Override
    public void onReceive(Context context, Intent intent) {

    String callingSIM = "";
    Bundle bundle = intent.getExtras();
    callingSIM =String.valueOf(bundle.getInt("simId", -1));

    if(callingSIM == "0"){
        // Incoming call from SIM1
    }
    else if(callingSIM =="1"){
        // Incoming call from SIM2
    }
    }

您可以使用SubscriptionInfo类尝试以下解决方案。

• 但这仅在电话号码与SIM卡相关联时才有效。

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
 SubscriptionManager subscriptionManager = SubscriptionManager.from(getApplicationContext());

 // Create a PhoneStateListener to detect incoming calls
 PhoneStateListener phoneStateListener = new PhoneStateListener() {
     @Override
     public void onCallStateChanged(int state, String phoneNumber) {
         if (state == TelephonyManager.CALL_STATE_RINGING) {
             // Retrieve the list of active subscriptions
             List<SubscriptionInfo> subscriptionInfoList = subscriptionManager.getActiveSubscriptionInfoList();
             if (subscriptionInfoList != null) {
                 // Loop through the list of active subscriptions
                 for (SubscriptionInfo subscriptionInfo : subscriptionInfoList) {
                     // Retrieve the phone number of the SIM card
                     String simPhoneNumber = telephonyManager.getLine1Number(subscriptionInfo.getSubscriptionId());
                     if (simPhoneNumber != null && simPhoneNumber.equals(phoneNumber)) {
                         // The incoming call belongs to this SIM card
                         int simSlotIndex = subscriptionInfo.getSimSlotIndex();
                         Log.d(TAG, "Incoming call belongs to SIM card in slot " + simSlotIndex);
                         break;
                     }
                 }
             }
         }
     }
 };

注册PhoneStateListener，

telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
