在googlemaps片段上放置一个工具栏

Question

我在尝试向地图项目添加工具栏时遇到问题。我收到了以下错误：

Caused by: android.view.InflateException: Binary XML file line #7: Error inflating class android.support.v7.widget.Toolbar

我不知道这个错误意味着什么，有人可以帮我解决这个问题吗？

这是我的XML

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  tools:context=".MapsActivity" >

    <android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_alignParentTop="true"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/material_blue_grey_800"
    android:minHeight="?attr/actionBarSize"/>

    <fragment
    android:id="@+id/map"
    android:layout_below="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.SupportMapFragment" />

     </RelativeLayout>

        }

和我的gradle

compile 'com.android.support:cardview-v7:21.0.+'
compile 'com.android.support:recyclerview-v7:21.0.+'
}

并且logcat是

Answer 1

设计库现已上市，因此请务必在SDK Manager中更新Android支持存储库。然后，您可以开始使用具有单个新依赖项的Design库：

compile＆＃39; com.android.support：design：22.2.0＆＃39;

请注意，由于Design库依赖于Support v4和AppCompat支持库，因此在添加Design库依赖项时将自动包含这些库。

您必须更改您的gradle支持库＆＃39; com.android.support：appcompat-v7：22.0＆＃39;到＆＃39; com.android.support：design：22.2.0＆＃39; 。
