错误在程序即将被了java.lang.RuntimeException:无法启动活动ComponentInfo {cse.svu / cse.svu.MainActivity}:java.lang.IllegalStateException:您需要使用Theme.AppCompat主题(或后裔)与本次活动。
在android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2059)
如果你在你的MainActivity延长ActionBarActivity,你将不得不更改父主题值-V11也。
因此,在值-V11的style.xml会 -
<! - RES /值-V11 /的themes.xml - >
< XML版本=1.0编码=UTF-8&GT?;
<资源>
<样式名称=QueryTheme父=@风格/ Theme.AppCompat>
<! - 与Theme.Holo设备上运行你的应用程序的任何自定义在这里 - >

errors are coming in the program are java.lang.RuntimeException: Unable to start activity ComponentInfo{cse.svu/cse.svu.MainActivity}: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity. at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2059)
If you are extending ActionBarActivity in your MainActivity, you will have to change the parent theme in values-v11 also. So the style.xml in values-v11 will be -
<!-- res/values-v11/themes.xml -->
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="QueryTheme" parent="@style/Theme.AppCompat">
<!-- Any customizations for your app running on devices with Theme.Holo here -->
</style>
