？attr/actionBar大小膨胀导致崩溃

Question

以下两行似乎都会导致应用程序通货膨胀崩溃。

android:layout_height="?attr/actionBarSize" 
    // or 
    android:layout_height="?android:attr/actionBarSize" 

任何想法？我正在尝试创建自己的栏，这是标准操作栏的默认大小。下面

例外：

Answer 1

尝试

@dimen/abc_action_bar_default_height_material 

，而不是

?android:attr/actionBarSize
