Android: 检查手机是否是双 SIM 卡

其他可能的选择:

You can use Java 反射 to get both IMEI numbers.

使用这些 IMEI 号码，你可以检查手机是否是 DUAL SIM 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.getImsiSIM1();
String imeiSIM2 = telephonyInfo.getImsiSIM2();


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");
}
}

And here is 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 getImsiSIM1() {
return imeiSIM1;
}


/*public static void setImsiSIM1(String imeiSIM1) {
TelephonyInfo.imeiSIM1 = imeiSIM1;
}*/


public String getImsiSIM2() {
return imeiSIM2;
}


/*public static void setImsiSIM2(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();


TelephonyManager telephonyManager = ((TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE));


telephonyInfo.imeiSIM1 = telephonyManager.getDeviceId();;
telephonyInfo.imeiSIM2 = null;


try {

try {

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


telephonyInfo.isSIM1Ready = telephonyManager.getSimState() == TelephonyManager.SIM_STATE_READY;
telephonyInfo.isSIM2Ready = false;


try {

}
}
}


return telephonyInfo;
}


private static String getDeviceIdBySlot(Context context, String predictedMethodName, int slotID) throws GeminiMethodNotFoundException {


String imei = null;


TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);


try{

if(ob_phone != null){
imei = ob_phone.toString();


}
} catch (Exception e) {

throw new GeminiMethodNotFoundException(predictedMethodName);
}


return imei;
}


private static  boolean getSIMStateBySlot(Context context, String predictedMethodName, int slotID) throws GeminiMethodNotFoundException {

}
}
} catch (Exception e) {
e.printStackTrace();
throw new GeminiMethodNotFoundException(predictedMethodName);
}


return isReady;
}




private static class GeminiMethodNotFoundException extends Exception {


private static final long serialVersionUID = -996812356902545308L;


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

编辑:

Getting access of methods like "getDeviceIdGemini" for other SIM slot's detail has prediction that method exist.

如果该方法的名称与设备制造商提供的名称不匹配，则该方法不会起作用。您必须为这些设备找到相应的方法名。

Finding method names for other manufacturers can be done using Java reflection as follows :

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();
}
}
