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：
