您靜音STREAM_RING

public class myPhoneStateChangeListener extends PhoneStateListener 
{ 
    private int mRingVolume; 
    Context context; 

    public myPhoneStateChangeListener(Context cxt) 
    { 
     context = cxt; 
    } 

    @Override 
    public void onCallStateChanged(int state, String incomingNumber) { 
     super.onCallStateChanged(state, incomingNumber); 
     if (state == TelephonyManager.CALL_STATE_RINGING) 
     { 
      mRingVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_RING); 
      mAudioManager.setStreamMute(AudioManager.STREAM_RING, true); 
      String phoneNumber = incomingNumber; 
      String ContactName = objUtility.getContactName2(context,phoneNumber); 

      if (RBSpkMde.isChecked()) 
      { 
       speakWords(ContactName); 
      } 
     } 
     if (state == TelephonyManager.CALL_STATE_IDLE) 
     { 
      mAudioManager.setStreamMute(AudioManager.STREAM_RING, false); 
      mAudioManager.setStreamVolume(AudioManager.STREAM_RING, 
         mRingVolume, AudioManager.FLAG_ALLOW_RINGER_MODES); 
     } 
    } 
    public void speakWords(String speech) 
    { 
    myTTS.speak("you have call from"+speech, TextToSpeech.QUEUE_FLUSH, null); 

    } 

}
