Format an array of strings with arguments

Question

I'd like to format an array of strings just like android used to format strings:

Usually we do:

strings.xml

<string name="welcome_messages">Hello, %1$s! You have %2$d new messages.</string>

In some java code:

Resources res = getResources();
String text = String.format(res.getString(R.string.welcome_messages), username, mailCount);

I'm looking for something like:

in some arbitrary xml:

    <string-array name="employee">
        <item>name: %1$s</item>
        <item>post: %2$s</item>
    </string-array>

in some java code:

Resources res = getResources();
String[] employee = ArrayString.format(res.getStringArray(R.string.employee), name, post);

Is there an elegant way to do that?

EDIT:

The next pieces of code is a workaround and I'm posting it just to help @Sufian, who asked for it in a comment. It's not a real answer once my question is about format the string array's content and the bellow code is formatting each string separately.

In some misc.xml:

<string-array
    name="string_array">
    <item>1st position: %1$d</item>
    <item>2nd position: %1$d</item>
</string-array>

Then, in java code:

res = getResources();
String[] sa = res.getStringArray(R.array.string_array);
for (int i = 0; i < sa.length; i++ ) {
    text += String.format(sa[i], i);
}

It seems that there is no elegant way to perform such formatting. You will need to iterate in each string array element and format it as your needs. — Plinio.Santos

Hmm. Any sample could which you could share? For now I'm just picking Strings by name using the following code snippet, and providing formatting arguments like with simple resource Strings. steven.bitsetters.com/2007/11/27/… — Sufian

Just use:

String text = String.format(res.getStringArray(R.array.myStringArray)[index], param1, param2);

getQuantityString may solve your problem.

Look at quantity strings in http://developer.android.com/guide/topics/resources/string-resource.html

Here's the specific API doc: http://developer.android.com/reference/android/content/res/Resources.html#getQuantityString(int,%20int,%20java.lang.Object...)

@Chuck_Norris quantity strings actually selects one kind of formatting in a set of many possibilities based in the amount such as zero, few, many... I need to use the entire array string and each array position may be a string formatted with arguments.
