android警告——Buttons in button bars should be border

Buttons in button bars should be borderless;
Bug原由，要寫兩個並排的按鈕，登陸按鈕和註冊按鈕，由於沒有背景圖，美工在忙別的事，沒空理。因此就出了這個問題

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

解決辦法：

 Set the style="?android:attr/buttonBarButtonStyle" attribute on each of the buttons, and set style="?android:attr/buttonBarStyle" on the parent layout.
給每一個Button設置style="?android:attr/buttonBarButtonStyle" 屬性。同時，給父佈局設置style="?android:attr/buttonBarStyle" 屬性。
