android警告——Buttons in button bars should be border

Buttons in button bars should be borderless;
Bug原由，要写两个并排的按钮，登陆按钮和注册按钮，由于没有背景图，美工在忙别的事，没空理。因此就出了这个问题

Buttons in button bars should be borderless; use style="?android:attr/buttonBarButtonStyle" (and ?android:attr/buttonBarStyle on the parent)

Issue: Ensures that buttons in button bars are borderless

Id: ButtonStyle

Button bars typically use a borderless style for the buttons. Set the style="?android:attr/buttonBarButtonStyle" attribute on each of the buttons, and set style="?android:attr/buttonBarStyle" on the parent layout

解决办法：

 Set the style="?android:attr/buttonBarButtonStyle" attribute on each of the buttons, and set style="?android:attr/buttonBarStyle" on the parent layout.
给每一个Button设置style="?android:attr/buttonBarButtonStyle" 属性。同时，给父布局设置style="?android:attr/buttonBarStyle" 属性。

文档看的好，你们都好。
