[英]How can I check whether Sim Cards are installed in both sim slots in an android device?
[英]How can I check whether the Sim Card is available in an android device?
我需要帮助以编程方式检查设备是否具有 SIM 卡。 请提供示例代码。
使用电话管理器。
http://developer.android.com/reference/android/telephony/TelephonyManager.html
作为Falmarri笔记,你将要使用所有的getPhoneType首先,要看看你甚至处理一个GSM电话。 如果是,那么您还可以获得 SIM 卡状态。
TelephonyManager telMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
int simState = telMgr.getSimState();
switch (simState) {
case TelephonyManager.SIM_STATE_ABSENT:
// do something
break;
case TelephonyManager.SIM_STATE_NETWORK_LOCKED:
// do something
break;
case TelephonyManager.SIM_STATE_PIN_REQUIRED:
// do something
break;
case TelephonyManager.SIM_STATE_PUK_REQUIRED:
// do something
break;
case TelephonyManager.SIM_STATE_READY:
// do something
break;
case TelephonyManager.SIM_STATE_UNKNOWN:
// do something
break;
}
编辑:
从 API 26( Android O 预览版)开始,您可以使用getSimState(int slotIndex)
查询 SimState 以获取单个 sim 插槽,即:
int simStateMain = telMgr.getSimState(0);
int simStateSecond = telMgr.getSimState(1);
如果您正在使用较旧的 api 进行开发,则可以使用TelephonyManager's
String getDeviceId (int slotIndex)
//returns null if device ID is not available. ie. query slotIndex 1 in a single sim device
int devIdSecond = telMgr.getDeviceId(1);
//if(devIdSecond == null)
// no second sim slot available
这是在 API 23 中添加的 - 文档在这里
您可以使用以下代码进行检查:
public static boolean isSimSupport(Context context)
{
TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE); //gets the current TelephonyManager
return !(tm.getSimState() == TelephonyManager.SIM_STATE_ABSENT);
}
找到了另一种方法来做到这一点。
public static boolean isSimStateReadyorNotReady() {
int simSlotCount = sSlotCount;
String simStates = SystemProperties.get("gsm.sim.state", "");
if (simStates != null) {
String[] slotState = simStates.split(",");
int simSlot = 0;
while (simSlot < simSlotCount && slotState.length > simSlot) {
String simSlotState = slotState[simSlot];
Log.d("MultiSimUtils", "isSimStateReadyorNotReady() : simSlot = " + simSlot + ", simState = " + simSlotState);
if (simSlotState.equalsIgnoreCase("READY") || simSlotState.equalsIgnoreCase("NOT_READY")) {
return true;
}
simSlot++;
}
}
return false;
}
感谢@Arun kumar 的回答,kotlin 版本如下
fun isSIMInserted(context: Context): Boolean {
return TelephonyManager.SIM_STATE_ABSENT != (context.getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager).simState
}
