发生样式运行时错误

Question

当我将values-v14/styles.xml文件中的值从更改时

parent="Theme.AppCompat.Light.DarkActionBar"   to:
 parent="android:Theme.Holo"

应用程序崩溃，logcat说：运行时错误！

我该怎么办？

这是日志：

Answer 1

您的类扩展了ActionBarActivity，这就是为什么您只能使用AppCompat主题。

如果你想使用holo，让你的类扩展Activity。示例

public class MainActivity extends Activity {
    ...
}

Answer 2

我不得不将main.xml设置为以下

<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
</style>
