你静音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);

    }

}
