我在我的Android应用程序中使用支持库的ToolBar。我尝试了2个小时来解决这个问题，但我无法取得成功。

我已将ToolBar添加为项目中的库＆amp; v7 appcompat也

    <android.support.v4.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    xmlns:android="http://schemas.android.com/apk/res/android" >

        <android.support.v4.widget.DrawerLayout
        android:id="@+id/drawer_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <FrameLayout
            android:id="@+id/container_body"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

            <ListView
                android:id="@android:id/list"
                android:background="@android:color/white"
                android:layout_width="305dp"
                android:layout_height="match_parent"
                android:layout_gravity="start"/>


</android.support.v4.widget.DrawerLayout>
    </android.support.v4.widget.Toolbar>

但我的应用程序因发送此日志消息而崩溃

抽屉布局不应位于工具栏内

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:app="http://schemas.android.com/apk/res-auto"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:orientation="vertical">

  <android.support.v4.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize" />

  <android.support.v4.widget.DrawerLayout
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    ...
  </android.support.v4.widget.DrawerLayout>
</LinearLayout>

我认为你已经添加了V7库。所以使用它的工具栏。

<script>javascript_include_tag "js/vendor/jquery.js"
