신호 강도 받기

Question

Android를 사용하여 CDMA/GSM 신호 강도를 얻는 방법을 알고 싶습니다.

참고 : getCdmaDbm() 메서드를 사용했지만 항상 -1을 반환합니다.

Answer 1

사용 PhoneStateListener '점점 SignalStrength에 대한의 onSignalStrengthsChanged :

TelephonyManager telephonyManager = (TelephonyManager)getSystemService(srvcName); 
AndroidPhoneStateListener phoneStateListener = new AndroidPhoneStateListener (this); 
telephonyManager.listen(phoneStateListener,  
PhoneStateListener.LISTEN_SIGNAL_STRENGTHS); 
    public class AndroidPhoneStateListener extends PhoneStateListener { 
     public static int signalStrengthValue; 

     @Override 
     public void onSignalStrengthsChanged(SignalStrength signalStrength) { 
      super.onSignalStrengthsChanged(signalStrength); 
      if (signalStrength.isGsm()) { 
       if (signalStrength.getGsmSignalStrength() != 99) 
        signalStrengthValue = signalStrength.getGsmSignalStrength() * 2 - 113; 
       else 
        signalStrengthValue = signalStrength.getGsmSignalStrength(); 
      } else { 
       signalStrengthValue = signalStrength.getCdmaDbm(); 
      } 
     } 

    }
