检索项目的父项时出错:找不到与给定名称"android:Theme.Material.Light"匹配的资源

Question

我在styles.xml中收到此错误:

检索项目的父项时出错:找不到与给定名称"android:Theme.Material.Light"匹配的资源.

在清单中:

<uses-sdk
    android:minSdkVersion="16"
    android:targetSdkVersion="21" />

Android Sdk经理:

我更新了所有的api 21和额外内容.

在订单和出口:

值-V21/styles.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="AppTheme" parent="android:Theme.Material.Light">

        <item name="android:colorPrimary">@color/primary</item>
        <item name="android:colorPrimaryDark">@color/primary_dark</item>
        <item name="android:colorAccent">@color/accent</item>
        <item name="android:textColorPrimary">@color/text_primary</item>
        <item name="android:textColor">@color/text_secondary</item>
        <item name="android:navigationBarColor">@color/primary_dark</item>

    </style>
</resources>  

安慰:

检索项目的父项时出错:找不到与给定名称"android:Theme.Material.Light"匹配的资源.

Material.Light主题需要API级别21的项目.设置项目构建目标的项目,从Properties->Android->Project Build Target到API 21.
