我想模仿我的应用程序的新材料设计开关和switchcompat工作pretty好。唯一的问题是周围出现触摸开关一个灰色的选择框，并真正从干净的外观带走。这是不是我可以删除？

I am trying to mimic the new material design switch in my app and the switchcompat works pretty well. The only problem is a grey selection box appears around the switch on touch and really takes away from the clean look. Is this something I can remove?

推荐答案

使用：

<android.support.v7.widget.SwitchCompat 
    ...
    android:background="@null" />
