我如何检测双卡设备中哪个卡的新拨出电话？

我知道我可以通过该接收器检测到新的拨出呼叫：

<receiver android:name=".NewOutgoingCallReceiver">
   <intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
   </intent-filter>
  </receiver> 

在 OnReceive 方法中，我想知道哪个 sim 进行此调用？

public class NewOutgoingCallReceiver extends BroadcastReceiver
{

@Override
public void onReceive( Context context, Intent intent )
  {
     // here i want to check which sim is making that new call 
  }
}

广播接收器收到的意图应该在捆绑包中包含一些额外信息，其中之一是“插槽” - 意思是 SIM 插槽。

您可以在上面的示例中得到这个，如下所示 - 这适用于 API 22 及更高版本：

public class NewOutgoingCallReceiver extends BroadcastReceiver
{
  @Override
  public void onReceive( Context context, Intent intent )
    {
       //check which sim is making that new call 
       String callSlot = "";
       Bundle bundle = intent.getExtras();
       callSlot =String.valueOf(bundle.getInt("slot", -1));
       if(callSlot == "0"){
           //Call is from SIM slot0
       } else if(callSlot =="1"){
          //Call is from SIM slot 1
       }
    }
}
