Android App不顯示工具欄

Question

我使用的是帶有導航抽屜的Android應用程序，但是當我將抽屜的代碼添加到現有代碼（Web視圖和底部欄）時，工具欄不會顯示。 抽屜工作。

這是我的代碼：

MainActivity.java

謝謝你的幫助！

Answer 1

您是否嘗試過使用android studio提供的Navigation Drawer模板，如果使用，則使用片段作為主要活動來代替活動

Answer 2

DrawerLayout充當窗口內容的頂級容器...要使用DrawerLayout，請將主內容視圖定位為第一個孩子，其寬度和高度為match_parent且沒有layout_gravity

您應該嘗試這種結構

DrawerLayout 
    CoordinatorLayout 
        AppBarLayout 
            <include> toolbar 
        <!-- activity layout (without toolbar) -->
    <!-- drawer layout  -->
