Question

我正在开发一个应用程序，其中我检查手机的服务状态，但当手机处于飞行模式时，它没有响应，或者手机没有SIM卡，那么它也无法正常工作。 PLZ帮我代码在下面

TelephonyManager telMng=(TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
        telMng.listen(new PhoneStateListener(){

                     @Override
                public void onServiceStateChanged (ServiceState serviceState){
                  super.onServiceStateChanged(serviceState);
                  String phonestate;
                 switch(serviceState.getState())
                  {
                 case ServiceState.STATE_IN_SERVICE:

                     Toast.makeText(getApplicationContext(), "phone is in service", Toast.LENGTH_LONG).show();
                     break;
                 case ServiceState.STATE_OUT_OF_SERVICE:
                     Toast.makeText(getApplicationContext(), "Phone is not in Service state", Toast.LENGTH_LONG).show();
                     break;
                     default:phonestate="Unknown";
                  }
                 /*

                  switch(serviceState.getState()){
                  case ServiceState.STATE_EMERGENCY_ONLY: phonestate ="STATE_EMERGENCY_ONLY"; ;break;
                  case ServiceState.STATE_IN_SERVICE: phonestate ="STATE_IN_SERVICE"; ;break;
                  case ServiceState.STATE_OUT_OF_SERVICE: phonestate ="STATE_OUT_OF_SERVICE"; ;break;
                  case ServiceState.STATE_POWER_OFF: phonestate ="STATE_POWER_OFF"; ;break;
                  default:phonestate = "Unknown";
                  } 
                  */  
            } 
        },  
        PhoneStateListener.LISTEN_SERVICE_STATE);

    }  
                                                                                                                                              i tried above code but its not working when phone is in flight mode or have not sim insert inside the phone what should i do plz help

检查手机是否处于飞行模式，如果存在SIM卡，请参阅此链接

以上不是正确答案，因为它只会告诉您SIM卡是否在服务中。

TelephonyManager.listen（PhoneStateListener（）{...}，PhoneStateListener.LISTEN_SERVICE_STATE）;

应该立即和周期性地发出服务状态。如果你混合使用sim状态和服务状态，你会得到错误的结果 - 你将停止服务，但是sim状态仍然准备就绪。
