Android Resource – Array of Arrays

You can almost do what you want. You have to declare each array separately and then an array of references. Something like this:

<string-array name="array01">
    <item name="id">1</item>
    <item name="title">item one</item>
</string-array>
<!-- etc. -->
<array name="array0">
    <item>@array/array01</item>
    <!-- etc. -->
</array>

Then in your code you do something like this:

Resources res = getResources();
TypedArray ta = res.obtainTypedArray(R.array.array0);
int n = ta.length();
String[][] array = new String[n][];
for (int i = 0; i < n; ++i) {
    int id = ta.getResourceId(i, 0);
    if (id > 0) {
        array[i] = res.getStringArray(id);
    } else {
        // something wrong with the XML
    }
}
ta.recycle(); // Important!
