Question

我找到了一些code来执行此操作，但它给了我一个异常（尝试在空对象引用上调用虚方法'java.lang.Class java.lang.Object.getClass（）'）。我正在使用我的Moto G第三代进行测试。下面是代码，如果我遗漏任何内容或任何其他方法，请告诉我。谢谢。

import android.app.PendingIntent;
import android.content.Context;
import android.os.IBinder;
import android.util.Log;

import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;


public class SimUtil {

    private static final String TAG = "SimUtil";

    public static boolean sendSMS(Context ctx, int simID, String toNum, String centerNum, String smsText, PendingIntent sentIntent, PendingIntent deliveryIntent) {

       SimUtil cls = new SimUtil();

        String name;

        try {
            if (simID == 0) {
                name = "isms";

            } else if (simID == 1) {
                name = "isms2";

            } else {
                throw new Exception("can not get service which for sim '" + simID + "', only 0,1 accepted as values");
            }

            try
            {
                Method method = Class.forName("android.os.ServiceManager").getDeclaredMethod("getService", new Class[]{String.class});
                method.setAccessible(true);
                Object param = method.invoke(null, new Object[]{name});

                if (param == null)
                {
                    throw new RuntimeException("can not get service which is named '" + name + "'");
                }
                method = Class.forName("com.android.internal.telephony.ISms$Stub").getDeclaredMethod("asInterface", new Class[]{IBinder.class});

                    throw new RuntimeException("can not get telephony which is named '" + name + "'");
                }


                method = stubObj.getClass().getMethod("sendText", String.class, String.class, String.class, String.class, PendingIntent.class, PendingIntent.class);

                method.invoke(null, new Object[]{ctx.getPackageName(), toNum, null, smsText, sentIntent, deliveryIntent});


            } catch (ClassNotFoundException e)

如果您的目标是API 22或更高版本。您可以使用以下代码获取SIM卡列表。您还可以允许用户选择SIM卡：

final ArrayList<Integer> simCardList = new ArrayList<>();
SubscriptionManager subscriptionManager;
subscriptionManager = SubscriptionManager.from(activity);
final List<SubscriptionInfo> subscriptionInfoList = subscriptionManager
                    .getActiveSubscriptionInfoList();
for (SubscriptionInfo subscriptionInfo : subscriptionInfoList) {
    int subscriptionId = subscriptionInfo.getSubscriptionId();
    simCardList.add(subscriptionId);
}

最后使用以下代码发送短信：

int smsToSendFrom = simCardList.get(0); //assign your desired sim to send sms, or user selected choice
SmsManager.getSmsManagerForSubscriptionId(smsToSendFrom)
                            .sendTextMessage(phoneNumber, null, msg, sentPI, deliveredPI); //use your phone number, message and pending intents
