java.lang.RuntimeException: Unable to start activity ComponentInfo……AppCompat does not support the current theme features

Android测试时出现闪退的问题,出现了如下所示异常:

java.lang.RuntimeException: Unable to start activity ComponentInfo{thonlon.example.cn.livetelecast/thonlon.example.cn.livetelecast.MainActivity}: java.lang.IllegalArgumentException: AppCompat does not support the current theme features: { windowActionBar: false, windowActionBarOverlay: false, android:windowIsFloating: false, windowActionModeOverlay: false, windowNoTitle: false }

启动不了应用的原因有很多,这里只是其中一例,这里的问题解决方式是:

在style.xml:

<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<!--<item name="android:windowNoTitle">true</item>-->
<!--<item name="windowActionBar">false</item>-->
</style>
</resources>

中不要禁用默认主题的头部布局……(不要加入这样的代码)

<item name="android:windowNoTitle">true</item>
<item name="windowActionBar">false</item>
