参考了前辈的博客：https://blog.csdn.net/ymcl_hx/article/details/53484797

直接封装出来一个工具类，记录一下

package com.dreamroom.device;import java.lang.reflect.Method;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;import org.json.JSONArray;
import org.json.JSONObject;import android.telephony.TelephonyManager;public class SimUtils {public JSONArray getAllSimInfo(TelephonyManager tel) throws Exception {Class<?> clazz = tel.getClass();//获取可以进行反射的字段List<EMethod> list = new ArrayList<>();Map<String, Integer> listIgnore = new HashMap<>();Method[] methods = clazz.getDeclaredMethods();for(Method method : methods) {String name = method.getName();if(!name.startsWith("get"))continue;if(listIgnore.get(name) != null)continue;listIgnore.put(name, 0);Method m1 = null;Method m2 = null;Method m3 = null;try {m1 = clazz.getDeclaredMethod(name); } catch(Exception e) {}try {m2 = clazz.getDeclaredMethod(name, int.class); } catch(Exception e) {}try {m3 = clazz.getDeclaredMethod(name, long.class); } catch(Exception e) {}if(m1 != null && ((m2 == null && m3 != null) || (m2 != null && m3 == null))) {Class<?> c1 = m1.getReturnType();Class<?> c2 = m2 == null ? null : m2.getReturnType();Class<?> c3 = m3 == null ? null : m3.getReturnType();if(m2 == null) {if(c1 == null || c1 != c3)continue;} else {if(c1 == null || c1 != c2)continue;}EMethod item = new EMethod(name, m2 == null ? 1 : 0, c1);list.add(item);}}listIgnore.clear();JSONArray array = new JSONArray();for(int i=0; i<10; i++) {JSONObject json = new JSONObject();for(EMethod em : list) {Method method = null;Object param = null;if(em.type == 0) {method = clazz.getDeclaredMethod(em.name, int.class);param = i;} else {method = clazz.getDeclaredMethod(em.name, long.class);param = new Long(i);}if(!method.isAccessible())method.setAccessible(true);String name = em.name.substring(3);Object value = null;try {value = method.invoke(tel, param);} catch(Exception e) {//前面已经对private设置了可访问，有些还是会报错，就不管这个了continue;}json.put(name, value);}if(json.optInt("SimState") == TelephonyManager.SIM_STATE_UNKNOWN || json.optInt("SimState") == TelephonyManager.SIM_STATE_ABSENT)continue;String imsi = json.optString("SubscriberId");if(imsi == null || imsi.length() == 0)continue;//根据imsi去重boolean repeact = false;for(int j=0; j<array.length(); j++) {if(imsi.equals(array.optJSONObject(j).optString("SubscriberId"))) {repeact = true;break;}}if(repeact)continue;array.put(json);}return array;}static class EMethod {public String name;public int type;	//0为int，1为longpublic Class<?> returnType;	//返回类型public EMethod(String name, int type, Class<?> returnType) {this.name = name;this.type = type;this.returnType = returnType;}}
}

传入TelephonyManager对象进行获取，返回JSONArray数据

TelephonyManager tel = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
JSONArray simList = SimUtils.getAllSimInfo(tel);

我的是双卡，返回的数据如下（对imsi等敏感数据进行了脱敏）：
