Is there a way to dynamically add values to an Android resource string-array?
E.g.:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string-array name="titles">
</string-array>
</resources>

What is your use case? You could simply build the string array list in code and pass it where needed.bond– bond2016-04-11 23:31:34 +00:00Commented Apr 11, 2016 at 23:31

@bond I want to store some data, and I'm wondering if there's an easier way such as writing to a resource xml file rather than using a database92AlanC– 92AlanC2016-04-11 23:36:12 +00:00Commented Apr 11, 2016 at 23:36

1if it is a small list, you could save it in shared preferences. See developer.android.com/reference/android/content/…, See, putStringSet() method. Also another alternative would be to use something like Realm db if you rather save objects. www.realm.iobond– bond2016-04-11 23:38:29 +00:00Commented Apr 11, 2016 at 23:38

No, because resources are read-only at runtime.

Yes! you can create a static array of strings in Android but dynamically adding values to an Android resource is not yet possible. It turns out that it’s easy to create and use a static array of strings in Android. Of course, you can do this in Java code, as I describe in my Java string array tutorial, but for Android, I’m talking about doing this in XML.
In short, this is how you define a static string array in an Android XML file:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string-array name="my_books">
<item>Scala Cookbook</item>
<item>Play Framework Recipes</item>
<item>How I Sold My Business: A Personal Diary</item>
<item>A Survival Guide for New Consultants</item>
</string-array>
</resources>
Then inside an Activity, Fragment, or other Java class, you can create a string array in Java from that XML like this:
Resources res = getResources();
String[] myBooks = res.getStringArray(R.array.my_books);
