Keeps String values separated in Android Resources

As you know you can write whatever resource you need inside res/values. I made an xml file for each gui/activity I'm using. Here's an example:

strings.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="hello">This is home!</string>
    <string name="app_name">Hattrick4Manager</string>
    <string name="oauth_button">Authorize me!</string>
    <string name="download_button">Syncronize</string>
    <string name="oauth_name">Authorization</string>
</resources>

update-ui.xml

<resources>
        <string name="inizio_download">Update Started...</string>
        <string name="fine_download">Update Completed...</string>
        <string name="update_title">Update</string>
        <string name="update_done">Done</string>
        <string name="update_inizio_club">Club...</string>
        <string name="update_inizio_arena">Arena...&l开发者_运维百科t;/string>
        <string name="update_inizio_fan">Fans...</string>
        <string name="update_inizio_matches">Matches...</string>
        <string name="update_inizio_league">League...</string>
        <string name="update_inizio_leaguefix">League Fixtures...</string>
        <string name="update_inizio_economy">Economy...</string>
        <string name="update_inizio_players">Players...</string>
</resources>

When I use this in the code I have to recall them like:

R.string.update_done

or

R.string.hello

my problem is that like this I have basically to add the prefix for every GUI I make. I would prefer doing something like:

R.string.update-ui.done

Is it possible?

You can create as many resource files as you want, but you can not perform the nested name referencing based on the filename: the Android aapt tool doesn't support arbitrary nested objects on the generated R object.

You might be able to do stuff like this in update-ui.xml:

<resources>
        <string name="update_ui_inizio_download">Update Started...</string>
        <string name="update_ui_fine_download">Update Completed...</string>
</resources>

and then use

R.string.update_ui_inizio_download

to reference the contents of the file
