我得到在Android 2.3.5一个RuntimeException,但我正在用Theme.AppCompat(RES /价值/的themes.xml).这是电话:http://www.gsmarena.com/samsung_galaxy_y_s5360-4117.php

 <!-- res/values/themes.xml -->
 <?xml version="1.0" encoding="utf-8"?>
 <resources>

     <style name="Theme.Styled" parent="@style/Theme.AppCompat">
         <item name="actionBarStyle">@style/QueryActionBar</item>
         <item name="android:actionBarStyle">@style/QueryActionBar</item>
     </style>

     <style name="QueryActionBar" parent="@style/Widget.AppCompat.ActionBar">
         <item name="background">@color/blueback</item>
         <item name="android:background">@color/blueback</item>
         <item name="backgroundSplit">@color/blueback</item>
         <item name="android:backgroundSplit">@color/blueback</item>
     </style>

 </resources>

这是values-v11的文件.

 <!-- res/values-v11/themes.xml -->
 <?xml version="1.0" encoding="utf-8"?>
 <resources>
    <style name="QueryTheme" parent="@android:style/Theme.Holo">
    <!-- Any customizations for your app running on devices with Theme.Holo here -->
    </style>
 </resources>

这是错误.

 java.lang.RuntimeException: Unable to start activity ComponentInfo{com.txt2lrn.www/com.txt2lrn.www.LandingActivity}: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with …

根据视频说明,我无法在全屏模式下运行Android应用.当它试图运行时,应用程序崩溃并出现错误.

"You need to use a Theme.AppCompat theme (or descendant) with this activity

清单文件

样式文件

<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>
</style>

可能有用的部分MainActivity

public class MainActivity extends AppCompatActivity {
