？attr/actionBar大小膨脹導致崩潰

以下兩行似乎都會導致應用程序通貨膨脹崩潰。？attr/actionBar大小膨脹導致崩潰

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

任何想法？我正在嘗試創建自己的欄，這是標準操作欄的默認大小。下面

例外：

你可以嘗試按ctrl +點擊'ATTR/actionBarSize'看看它的初始化？ R文件 –

把你的XML文件，所以我們可以看到什麼是錯誤 –

''這個工作適合我..你可能採取了錯誤的佈局... –

嘗試

@dimen/abc_action_bar_default_height_material

，而不是

?android:attr/actionBarSize
