我遇到Theme.AppCompat.Light.NoActionBar主题的问题，我不确定这是一个错误还是一些不正确的事情。
这就是我定义我的应用主题的方式：
<style name="Theme.DesignDemo" parent="Base.Theme.DesignDemo"></style>
<style name="Base.Theme.DesignDemo" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">@color/primaryColour</item>
<item name="colorPrimaryDark">@color/primaryDarkColour</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
然后我将其应用于清单中的应用程序，如下所示：
<application
android:name=".MainApplication"
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/Theme.DesignDemo">
...
</application>
当我将应用程序从IDE直接运行到我的手机或模拟器并且它有一个操作栏时，这很有效。
但是一旦我生成签名的APK;应用程序丢失了操作栏。
知道我在这里做错了什么吗？

答案 0 :(得分：0)
我设法找到了我面临的上述问题的解决方案......我用Android Studio默认替换了我的样式定义
在styles.xml中
<!-- 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>
</style>
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
然后在styles.xml（v21）
中<resources>
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@android:color/transparent</item>
</style>
我从Eclipse导入了这个项目，我试图像在Eclipse中一样使用这些样式。
一切都好了。
