膨胀类android.support.v7.widget.Toolbar的错误
我在互联网上也发现了同样的问题，但是在答案中却没有找到解决方法.
I have found the same problem on the internet but I haven't found the solution in the answers.
这是我的styles.xml
This is my 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)
Here is my 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>
要在.xml中定义工具栏
To define the toolbar in .xml
<?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MainActivty中，我只包含该工具栏:
And in my MainActivty I just include that toolbar:
<include layout="@layout/toolbar" />
最后是我的MainActivity.java的标头
And finally the header of my MainActivity.java
public class MainActivity extends android.support.v7.app.ActionBarActivity
implements NavigationDrawerFragment.NavigationDrawerCallbacks {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); //Here stops my application
}

预先感谢您的帮助.
推荐答案
错误的原因是，在工具栏xml中，?attr前缀是指支持库主题中的属性.另一方面，在上述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，充气机无法解析支持库的属性，例如?attr/actionBarSize.
The cause of the error is that, in the toolbar xml, the ?attr prefix refers to attributes in support library themes. On the other hand, under v22 of style.xml above, the system theme android:Theme.Material.Light.NoActionBar instead of a support library theme is used. The inflater therefore cannot resolve attributes of the support library such as ?attr/actionBarSize.
在style.xml中使用支持库主题Theme.AppCompat.Light.NoActionBar(与版本无关)可以解决此问题.
Using the support library theme Theme.AppCompat.Light.NoActionBar in style.xml (regardless of version) addresses the issue.
