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

我在styles.xml中遇到此错误：

Error retrieving parent for item: No resource found that matches the
given name ‘android:Theme.Material.Light’.

在清单中：

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

Android Sdk Manager：

我更新了所有的api 21和其他功能.

订购和出口：

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：

我不知道为什么仍然会发生此错误.任何人都可以帮助我.谢谢.

解决方法:

Error retrieving parent for item: No resource found that matches the
given name ‘android:Theme.Material.Light’.

Material.Light主题要求项目的API级别为21.将项目的项目构建目标从“属性”->“ Android”->“项目构建目标”设置为API 21.
