Android issue with custom themes

Question

My android project

AndoidManifest.xml has

 <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.myfirstapp" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="11" android:targetSdkVersion="17" /> <application android:allowBackup="true" android:debuggable="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/CustomActionBarTheme" > <activity android:name="com.example.myfirstapp.MainActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="com.example.myfirstapp.DisplayMessageActivity" android:label="@string/title_activity_display_message" android:parentActivityName="com.example.myfirstapp.MainActivity" > <meta-data android:name="android.support.PARENT_ACTIVITY" android:value="com.example.myfirstapp.MainActivity" /> </activity> </application> </manifest> 

When I try to implement a custom theme in res\values\themes.xml

 <?xml version="1.0" encoding="utf-8"?> <resources> <!-- the theme applied to the application or activity --> <style name="CustomActionBarTheme" parent="@style/Theme.Holo.Light.DarkActionBar"> <item name="android:actionBarStyle">@style/MyActionBar</item> </style> <!-- ActionBar styles --> <style name="MyActionBar" parent="@style/Widget.Holo.Light.ActionBar.Solid.Inverse"> <item name="android:background">@drawable/actionbar_background</item> </style> </resources> 

I get erros indicating

Error retrieving parent for item: No resource found that matches the given name '@style/Theme.Holo.Light.DarkActionBar'. and Error retrieving parent for item: No resource found that matches the given name '@style/ Widget.Holo.Light.ActionBar.Solid.Inverse'.

Answer 1

You should write android: in front of the style, namely @android:style/Theme.Holo.Light.DarkActionBar .

Answer 2

They did not include examples of all the files used or how they made files or what files should be created.

It seems that in addition, they forgot to use @android, they did not mention that files, for example actionbar_background.xml, should be created under res / drawable / in this case, or that theme.xml should be created under res / values ​​/

They seem to have created styles (for images in the manual) using:
http://jgilfelt.imtqy.com/android-actionbarstylegenerator/

And the files generated themselves as follows:
http://developer.android.com/guide/topics/resources/drawable-resource.html

They do the same in the rest of the chapter. The guide is pretty confusing when you are new.

From the question I asked, I assume they used the Android Developer Guide .

Answer 3

you can add theme.xml to styles.xml
