我为我的项目使用android.support库，我使用android 4.4开发了我的应用程序并且一切正常但我的问题出现在我尝试在Android Lollipop设备中运行应用程序时。

当它使用工具栏加载Activity时，应用程序将停止并返回此错误。

错误导致类android.support.v7.widget.Toolbar错误

我在互联网上发现了同样的问题，但我没有在答案中找到解决方案。

这是我的styles.xml 

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
<!-- Base theme applied no matter what API -->
    <item name="android:windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="colorPrimary">@color/primary</item>
    <item name="colorPrimaryDark">@color/dark_primary</item>
    <item name="colorAccent">@color/accent_color</item>
</style>

这是我的styles.xml（v22）

<resources>
    <!-- Base application theme. -->
    <style name="AppTheme" parent="android:Theme.Material.Light.NoActionBar">
        <item name="colorPrimary">@color/primary</item>
        <item name="colorPrimaryDark">@color/dark_primary</item>
        <item name="colorAccent">@color/accent_color</item>
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>
</resources>

在.xml中定义工具栏

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:local="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/mitoolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    local:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    local:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    tools:showIn="@layout/activity_main" />

在我的MainActivty中，我只包含该工具栏：

<include layout="@layout/toolbar" />

最后是我的MainActivity.java标题

public class MainActivity extends android.support.v7.app.ActionBarActivity
        implements NavigationDrawerFragment.NavigationDrawerCallbacks {

     super.onCreate(savedInstanceState);
     setContentView(R.layout.activity_main); //Here stops my application
}

继承logcat

提前感谢您的帮助。

答案 0 :(得分：9)

错误原因是，在工具栏xml中，?attr前缀是指支持库主题中的属性。另一方面，在上面style.xml的v22下，使用系统主题android:Theme.Material.Light.NoActionBar而不是支持库主题。因此，inflater无法解析支持库的属性，例如?attr/actionBarSize。

使用style.xml中的支持库主题Theme.AppCompat.Light.NoActionBar（无论版本如何）解决了该问题。

答案 1 :(得分：0)

在我的情况下相同的错误，但在android axml文件中没有？attr的症状

它看起来像是Xamarin.Appcombat的兼容性问题（我在网上找到了某个地方）

尝试将同一项目部署到较低的Android API

在我的情况下，Android模拟器API 21出现上述错误，但另一个使用Android API 18的模拟器完全没有问题
