静音其实就是关闭麦克风让对方听不见

 

private boolean isJingyi = false;

//获取音频服务
AudioManager audioManager = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE);
//设置声音模式
audioManager.setMode(AudioManager.STREAM_MUSIC);

if (isJingyi) {
    //关闭麦克风
    audioManager.setMicrophoneMute(false);
    iv_jingyin.setImageResource(R.mipmap.ic_jingyin1);
    isJingyi =false;
}else {
    audioManager.setMicrophoneMute(true);
    iv_jingyin.setImageResource(R.mipmap.ic_jingyin);
    isJingyi = true;
}
