我有一个导航抽屉工作了一段时间，但后来我决定更新它以使用Toolbar而不是默认的支持操作栏。现在，我有一种情况，当我点击汉堡包菜单时，导航抽屉不会打开。但是，我可以从左向右滑动并打开它。问题是，它现在是空的。

我知道NavDrawerItem的东西看起来有点不稳定，但我已经证实它适用于旧的导航抽屉（工具栏前），而它所做的只是填充{{1}的一些逻辑带有图标的项目并将它们放在适当的分组中。所以，我相信这不是问题所在。
即使它是，我应该得到除空白背景之外的东西，因为导航抽屉的布局实际上设置了具有绿色背景的ListView的标题，我没有看到。< / p>
修改：
根据@ blacksh33p的评论，我删除了处理不同API级别的代码，并将ListView构造函数更改为：
mDrawerToggle，然后将Toolbar更改为以下内容：
mDrawerToggle但是，我最终得到了相同的结果。 ：（

从onCreate移除代码并添加到setContentView

我正在使用drawerLayout使用我自己的工具栏开发一个应用程序，它在我的设备上运行良好（android 5.0.1）。为此，我有一个像这样的xml布局：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="50dp"
android:background="#F78B1E"
android:minHeight="?attr/actionBarSize" />
<android.support.v4.widget.DrawerLayout
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center_vertical">
<!-- The main content view -->
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<!-- The navigation drawer -->
<ListView
android:id="@+id/left_navigation"
android:layout_width="400dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="#fff"
/>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
