Java 如何在安卓双卡系统中发送短信？

在安卓系统中，如何使用双sim卡发送短信以实现广播目的？？如何在android中检测双sim卡？用户希望选择sim卡发送短信广播。在android中，在android的双sim卡中设置发送消息的默认sim卡

谢谢

您可以使用Java反射来获取这两个IMEI编号

使用这些IMEI号码，您可以检查手机是否为双卡

尝试以下活动：

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        TelephonyInfo telephonyInfo = TelephonyInfo.getInstance(this);

        String imeiSIM1 = telephonyInfo.getImeiSIM1();
        String imeiSIM2 = telephonyInfo.getImeiSIM2();

        boolean isSIM1Ready = telephonyInfo.isSIM1Ready();
        boolean isSIM2Ready = telephonyInfo.isSIM2Ready();

        boolean isDualSIM = telephonyInfo.isDualSIM();

        TextView tv = (TextView) findViewById(R.id.tv);
        tv.setText(" IME1 : " + imeiSIM1 + "\n" +
                " IME2 : " + imeiSIM2 + "\n" +
                " IS DUAL SIM : " + isDualSIM + "\n" +
                " IS SIM1 READY : " + isSIM1Ready + "\n" +
                " IS SIM2 READY : " + isSIM2Ready + "\n");
    }
}

下面是TelephonyInfo.java：

import java.lang.reflect.Method;

import android.content.Context;
import android.telephony.TelephonyManager;

public final class TelephonyInfo {

    private static TelephonyInfo telephonyInfo;

        return imeiSIM1;
    }

    /*public static void setImeiSIM1(String imeiSIM1) {
        TelephonyInfo.imeiSIM1 = imeiSIM1;
    }*/

    public String getImeiSIM2() {
        return imeiSIM2;
    }

    /*public static void setImeiSIM2(String imeiSIM2) {
        TelephonyInfo.imeiSIM2 = imeiSIM2;
    }*/

    public boolean isSIM1Ready() {
        return isSIM1Ready;
    }

    public boolean isSIM2Ready() {
        return isSIM2Ready;
    }

    /*public static void setSIM2Ready(boolean isSIM2Ready) {
        TelephonyInfo.isSIM2Ready = isSIM2Ready;
    }*/

    public boolean isDualSIM() {

    }

这对她有好处。她成功地为三星Duos设备中的两个SIM卡获得了两个IMEI号码。

此解决方案适用于API级别22+，无需反射。它基于这里提出的解决方案

基本上，要检测您是否有两张或更多sim卡，您需要检查此情况

SubscriptionManager localSubscriptionManager = SubscriptionManager.from(context);
            if (localSubscriptionManager.getActiveSubscriptionInfoCount() > 1) {
//do you stuff here
}

然后根据用户选择的sim卡插槽（0，1，…），您可以在选定的sim卡上发送短信。下面是一个实现这一点的方法

public static boolean sendSMS(Context context, int simID, String toNum, String centerNum, String smsText, PendingIntent sentIntent, PendingIntent deliveryIntent) {
    SmsManager smsMan = SmsManager.getDefault();
    int[] param;
    Method method = null;
    try {
        SubscriptionManager localSubscriptionManager = SubscriptionManager.from(context);
        if (localSubscriptionManager.getActiveSubscriptionInfoCount() > 1) {
            List localList = localSubscriptionManager.getActiveSubscriptionInfoList();
            SubscriptionInfo simInfo = (SubscriptionInfo) localList.get(simID);
            SmsManager.getSmsManagerForSubscriptionId(simInfo.getSubscriptionId()).sendTextMessage(toNum, null, smsText, null, null);
        }
        return true;
    } catch (Exception e) {
        Log.e("SmsSimUtil.sendSMS", "Exception:" + e.getMessage());
    }
    return false;
}

不要忘记在应用程序AndroidManifest.xml中添加这些权限

<uses-permission android:name="android.permission.SEND_SMS"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

@Mohamand rababah是检测双sim卡的答案。但是如何通过特定的SIM卡发送短信，您是否有使用特定SIM卡发送短信的解决方案。如果你知道，请在这里分享。谢谢你输入我的密码。。我已经解决了这个问题：。。很好，lucklocalSubscriptionManager.getActiveSubscriptionInfoCount（）为我返回了0。不知道是什么原因造成的。你有什么建议吗？

public static boolean sendSMS(Context context, int simID, String toNum, String centerNum, String smsText, PendingIntent sentIntent, PendingIntent deliveryIntent) {
    SmsManager smsMan = SmsManager.getDefault();
    int[] param;
    Method method = null;
    try {
        SubscriptionManager localSubscriptionManager = SubscriptionManager.from(context);
        if (localSubscriptionManager.getActiveSubscriptionInfoCount() > 1) {
            List localList = localSubscriptionManager.getActiveSubscriptionInfoList();
            SubscriptionInfo simInfo = (SubscriptionInfo) localList.get(simID);
            SmsManager.getSmsManagerForSubscriptionId(simInfo.getSubscriptionId()).sendTextMessage(toNum, null, smsText, null, null);
        }
        return true;
    } catch (Exception e) {
        Log.e("SmsSimUtil.sendSMS", "Exception:" + e.getMessage());
    }
    return false;
}
