I am programming an application contains layouts with some views. I load these colors from values/colors.xml. Now, I want to define multiple themes for my application, e.g. Blue and Green (some sort of blue and green colors). My question is how can I define two colors.xml file and load it based on some conditions or choosing by user. What I want is some thing like strings.xml that we can load strings based on locale defined.
Thanks in advance.
string.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="white">#FFFFFF</string>
</resources>
values-fr/strings.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="white">#EEEEEE</string>
</resources>
button.setBackgroundColor(Integer.parseInt(getString(R.string.white)));

I want to use a different string resource on small screens but Android always uses the default string. Am I doing it wrong?
/res/values/strings.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="continue">Continue</string>
</resources>
/res/values-large/strings.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="continue">Continue to Next Page</string>
</resources>
#string/continue always resolves to "Continue", even on large screens. It does, however use the dimensions in /res/values-large/dimens.xml so I'm sure I'm using the right resource qualifier. I also tried /res/values-w550dp/strings.xml and it didn't work either.
Am I doing something wrong or is this a limitation of Android?
values-large is only available for dimens and styles, but not for string resources.
one could possibly add custom string-arrays and then look them up accordingly.
see Android Resource Types.
I want to support multiple languages in my app using sqlite database and xml resources.
For example, the user can insert transaction objects. Each transaction has a category.
<?xml version="1.0" encoding="utf-8"?>
<resources>
<array name="categories">
<item>#string/category1</item>
<item>#string/category2</item>
<item>#string/category3</item>
<item>#string/category4</item>
<item>#string/category5</item>
</array>
</resources>
What is the correct approach to use the above values in sqlite? Should a table be created or I can use them directly from xml?
If I want the user to be able to also add his own categories, how the multi-language thing should work?
Please read the two following google guides about supporting different languages and localizing:
http://developer.android.com/training/basics/supporting-devices/languages.html
http://developer.android.com/guide/topics/resources/localization.html
the normal way is to create a strings.xml for every language:
For Storing your categories in your SQLite Database you should enumerate your Categories and store only the numbers, so you are independent of the spelling. Adding a user defined Catergory should also work this way.

Is there a way to add localization setting in my app? I'm going to add a preference/setting in my app and there is a localization option. So the user can change the language I have provided from the values string.
I was googling around but found nothing. Wondering you guys can help me, and give example or link to the tutorial.
You don't need to provide a setting for that, Android will do that for you. You just have to provide the translations for the languages you want to support.
You can do this for French for example by creating a folder named res/values-fr in your resources folder and putting your translations in there.
so in the res/values folder you would have a strings.xml file :
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="q_map">Map</string>
</resources>
and in the res/values-fr you woud have another string.xml file :
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="q_map">Carte</string>
</resources>
Your app will use the translation that best matches the language that the user has selected on their device.
In my app I have a lot of controls that should change their text color when changing drawable state. Android provides a way to do it - color state lists. For each color state list I have to create a separate XML file, like this:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:color="#398ede" android:state_pressed="true"/>
<item android:color="#808080"/>
</selector>
Is there any way to avoid creating a separate file for each color state list and define them all in a single file?
You must have found the answer by now, but for the sake of those who come to this link again, here's how we do it.
If you have a resource file defining multiple colors like this:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="xBlack">#FF000000</color>
<color name="xYellow">#FFFFFF00</color>
</resources>
You need to put this file under values (and not in colors)
To access the values you need to use:
dummy_button_id.setBackgroundColor(getResources().getColor(R.color.xBlack));
I have a settings.xml file that I use to set various global variables within my app. I want to be able to create sub xml files that I include in the settings.xml file because depending on the client, I change settings in this file so I want to make it easier on myself.
I know that there is a way to include layout files this way but I can't find any documentation that shows how to do this with plain XML on Android.
Any help would be much appreciated.
I think all you have to do is make an additional file which includes the settings you want.
Ie, I have strings.xml in values
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="main_title">Hello there</string>
</resources>
And I can create additionalstrings.xml in the values folder
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="additional">How are you?</string>
</resources>
I can refer to either R.string.main_title or R.string.additional, without having to say the file it came from.
