Android关于Theme.AppCompat相关问题的深入分析
No resource found that matches the given name ‘@style/Theme.AppCompat.Light’
AppTheme相关

遇到了一个问题：

想设置一个全屏，在AndroidMainfest.xml的标签的配置如下：

        <activity
            android:name=".activity.ManagerActivity"
            android:screenOrientation="landscape"
            android:theme="@style/AppTheme" />```

values/style

    <!-- Base application theme. -->
    <style name="AppTheme" parent="android:Theme.DeviceDefault.Light.NoActionBar.Fullscreen">
        <item name="android:windowNoTitle">true</item>
    </style>

原因：

从错误提示中提到Theme.AppCompat theme，因为我们的activity一定是继承了兼容包中的类(我这里继承AppCompatActivity)，
所以就要使用与其配合的AppCompat的theme才行。

解决办法：

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="android:windowFullscreen">true</item>
    </style>

下面是错误提示：
