这是一种解决方法，但由于 ActionBar 选项卡在 21 API 中已弃用，因此您可以在布局中使用选项卡（如 TabHost）。在这种情况下，抽屉将显示在选项卡上方。

代码：

    TabHost tabHost = (TabHost) findViewById(android.R.id.tabhost);
    tabHost.setup();

    TabHost.TabSpec tabSpec;
    tabSpec = tabHost.newTabSpec("1");
    tabSpec.setIndicator("Tab");
    tabSpec.setContent(R.id.list_fragment);
    tabHost.addTab(tabSpec);

    tabHost.setOnTabChangedListener(listener);

并将其添加到布局中：

<TabHost
    a:id="@android:id/tabhost"
    a:layout_width="match_parent"
    a:layout_height="match_parent">
    <LinearLayout
        a:layout_width="match_parent"
        a:layout_height="match_parent"
        a:orientation="vertical">
        <TabWidget
            a:id="@android:id/tabs"
            a:layout_width="match_parent"
            a:layout_height="wrap_content">
        </TabWidget>
        <FrameLayout
            a:id="@android:id/tabcontent"
            a:layout_width="match_parent">

            </FrameLayout>
    </LinearLayout>
</TabHost>

我认为你最好使用像ViewPagerIndicator这样的库。ActionBar 被识别为装饰并显示在窗口顶部，而 DrawerLayout 被绘制为窗口中的对象。

不确定他们是否会在未来的版本中修复它，但 ViewPagerIndicator 很容易设置和自定义。
