推荐答案

此答案可在通话过程中使您的麦克风静音:

This answer works to mute your microphone during a call:

Boolean isMuted = false;

然后在您的活动中说一个onClick

Then in your event, say an onClick

AudioManager audioManager = (AudioManager) getContext().getSystemService(Context.AUDIO_SERVICE);
if(!isMuted){

   if((audioManager.getMode()== AudioManager.MODE_IN_CALL)||(audioManager.getMode()== AudioManager.MODE_IN_COMMUNICATION)){
   audioManager.setMicrophoneMute(true);
  }
  isMuted = true;

 }else{

  if((audioManager.getMode()== AudioManager.MODE_IN_CALL)||(audioManager.getMode()== AudioManager.MODE_IN_COMMUNICATION)){
    audioManager.setMicrophoneMute(false);
    }
  isMuted = false;
 }

记住要在清单中启用权限

Remember to enable permissions in your manifest:

<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
