如何在Android中发送短信用双卡进行播放不是故意？怎么能在android中检测双卡？用户想为发送短信广播选择SIM卡。在android中设置默认的sim卡，用于在android中以双卡方式发送msg。
谢谢，

参考https://stackoverflow.com/a/17499889/2771869
您可以使用Java反射来获取两个IMEI号。
使用这些IMEI号码，您可以查看天气电话是否为双卡。
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");
}
}
这是TelephonyInfo.java：
import java.lang.reflect.Method;
import android.content.Context;
import android.telephony.TelephonyManager;
public final class TelephonyInfo {
private static TelephonyInfo telephonyInfo;
private String imeiSIM1;
private String imeiSIM2;
private boolean isSIM1Ready;
private boolean isSIM2Ready;
public String getImeiSIM1() {
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 static void setSIM1Ready(boolean isSIM1Ready) {
TelephonyInfo.isSIM1Ready = isSIM1Ready;
}*/
public boolean isSIM2Ready() {
return isSIM2Ready;
}
/*public static void setSIM2Ready(boolean isSIM2Ready) {
TelephonyInfo.isSIM2Ready = isSIM2Ready;
}*/
public boolean isDualSIM() {
return imeiSIM2 != null;
}
private TelephonyInfo() {

public static TelephonyInfo getInstance(Context context){
if(telephonyInfo == null) {
telephonyInfo = new TelephonyInfo();

try {

telephonyInfo.imeiSIM2 = getDeviceIdBySlot(context, "getDeviceId", 1);
} catch (GeminiMethodNotFoundException e1) {
//Call here for next manufacturer's predicted method name if you wish

telephonyInfo.isSIM1Ready = telephonyManager.getSimState() == TelephonyManager.SIM_STATE_READY;

编辑：
获取其他SIM插槽细节的“getDeviceIdGemini”等方法可以预测该方法存在。
如果该方法的名称与设备制造商给出的名称不匹配，则该名称不起作用。您必须为这些设备找到相应的方法名称。
可以使用Java反射查找其他制造商的方法名称，如下所示：
public static void printTelephonyManagerMethodNamesForThisDevice(Context context) {
TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
Class<?> telephonyClass;
try {
telephonyClass = Class.forName(telephony.getClass().getName());
Method[] methods = telephonyClass.getMethods();
for (int idx = 0; idx < methods.length; idx++) {
System.out.println("\n" + methods[idx] + " declared by " + methods[idx].getDeclaringClass());
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}

正如Seetha在评论中指出的那样：
telephonyInfo.imeiSIM1 = getDeviceIdBySlot(context, "getDeviceIdDs", 0);
telephonyInfo.imeiSIM2 = getDeviceIdBySlot(context, "getDeviceIdDs", 1);
这对她有用。她成功地为Samsung Duos设备中的两个SIM卡获取了两个IMEI号码。

此解决方案适用于API级别22+，无需任何反思。它基于此处https://stackoverflow.com/a/51380282/3427883提出的解决方案。
要基本检测您是否有两张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，...），可以在所选的SIM卡上发送SMS。下面是执行此操作的方法
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;
}
不要忘记在您的应用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"/>
