升级到AppCompat V22.1.0版本后，获取AppCompat不支持当前主题特性异常

Question

以前，我在我的项目中使用AppCompat21.1.2版，目的是用工具栏切换材料设计。但是在升级到AppCompat V22.1.0之后，我的应用程序开始变得奇怪。我甚至尝试了一些解决方案，如下所示

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

<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">

 <style name="MainActivityTheme" parent="Theme.AppCompat.NoActionBar">
        <item name="colorPrimary">@color/white</item>
        <item name="colorPrimaryDark">#F2F2F2</item>
        <item name="android:windowNoTitle">true</item>
        <item name="windowNoTitle">true</item>
        <item name="windowActionBar">false</item>
        <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
        <item name="colorControlActivated">@color/yellow</item>
    </style>

Answer 1

谢谢大家的回复。我自己通过移除线解决了我的问题

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

由于添加windowNoTitle两次而发生错误，如下所示

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