Creating a list of integers in XML for android.

Question

I would like to create a list of Integers in the /res folder of an android project. However, I want those integers to point resources in /res/raw. So for example, I would like something like this:

<?xml version="1.0" encoding="utf-8"?>
    <resources>
        <integer-array name="built_in_sounds">
            <item>@raw/sound</item>
    </integer-array>
</resources>

But id doesn't look like I can do that, is there any way to do this? Or should I just create the list in a java class?

Thank you

Hi Leif,

In this case, I think it's not a good idea to use two integers just to control a resource (sorry for my English skill, it may cause you misunderstand) I mean, each resource has its own integer id in the class R in the gen folder, and now you create another integer to display the id, it's no need to do that.

I have some trick to handle what you want: Rename the resources you want in order, and in R class, they will be in order and increase by 1, then you can use that.

Here is an example: I have 5 resources in raw folder, they are: sound01, sound02, sound03, sound04, sound05

And in the R file, I get:

public static final class raw {
        public static final int sound01=0x7f040000;
        public static final int sound02=0x7f040001;
        public static final int sound03=0x7f040002;
        public static final int sound04=0x7f040003;
        public static final int sound05=0x7f040004;
    }

It's an array of integers, right?

And for the for loop, example:

for(int i = R.raw.sound01; i<= R.raw.sound02; i++) {
//do somethings
}

Since my English skill is not good, hope you can get my point!

Answer 2

Okay, I finally found out how to do this. What I did, was just create a database. The database stored all of the primitives I needed to store, and than pointers to the objects that I needed to reference. Apparently the android SDK comes with support for SQLite.

Answer 3

To do this in XML without a database, see: http://developer.android.com/guide/topics/resources/more-resources.html#Integer
