如果双 SIM 卡槽之一的 SIM 卡发生更改，如何检索该卡的信息？

我知道我们可以使用 TelephonyManager 类检索单张 Sim 卡的信息。但如何检索多张SIM卡的信息呢？假设我的手机丢失了，有人更换了其中一个插槽中的 SIM 卡。我如何接收 IMEI 号码、电话号码等信息？我只在更换 Sim 卡时才需要这些信息。

在 TelephonyManager 类中，有直接方法来检索这些信息（如 IMEI 号码、电话号码、电话网络类型等），但这些信息仅适用于一张 Sim 卡。如何接收有关多张 SIM 卡的所有信息。 P.S-SubscriptionManager 类没有像 TelephonyManager 类那样的直接方法。

    import android.content.Context;
        import android.support.v7.app.AppCompatActivity;
        import android.os.Bundle;
        import android.telephony.SubscriptionInfo;
import android.telephony.SubscriptionManager;
import android.widget.TextView;

import java.util.List;

import static android.R.id.content;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        int subID,simposition,content;
        String carrier,number;
        TextView textView2=(TextView)findViewById(R.id.text);
        SubscriptionManager subManager=(SubscriptionManager)getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE);

        List<SubscriptionInfo> subInfoList=subManager.getActiveSubscriptionInfoList();

        for(int i=0;i<subInfoList.size();i++)
        {
           subID = subInfoList.get(i).getSubscriptionId();
            simposition = subInfoList.get(i).getSimSlotIndex();
             content=subInfoList.get(i).describeContents();
          carrier= (String) subInfoList.get(i).getCarrierName();
            number= subInfoList.get(i).getNumber();
        }

       /* String info2="Sim Details:\n";
        info2+="\n SubId:"+subID;
        info2+="\n Sim position:"+simposition;
        info2+="\n contents:"+content;
        info2+="\n carrier:"+carrier;
        info2+="\n number:"+number;
        textView2.setText(info2);*/
    }
}

您可以使用此工作示例代码来解决您的问题。

        private static class ITgerMethodNotFoundException extends Exception {
            private static final long serialVersionUID = -996812356902545308L;

            public ITgerMethodNotFoundException(String info) {
                super(info);
            }

        }
    }

我希望这有帮助。
