Luk en Activity når brugeren klikker alle steder på skærmen

Hej Alle sammen

I mit android projekt har jeg lavet en Activity som nedarver fra klassen ListActivity. Selve min activity bruges til at vise noget simpelt tekst data i et ListView, men denne view har ikke nogen Button control, da jeg ikke ønsker dette, vil meget hellere have at brugeren skal kunne trykke/klikke en gang på skærmen (lige meget hvor) med sin finger, for at denne activity skal afslutte/lukke. Har prøvet at lave en onClickListener() event, for selve activityen, men denne er ikke at finde nogen steder for ListActivity, så hvordan får jeg lavet denne listener?

Jeg har allerede lavet en onListItemClick() event, men denne event kører kun når jeg klikker på et list item, og min activity kan være tom for information (Det er en highscore liste). Min kode ser således ud indtil nu - Undskyld rodet, men den er ikke færdigudviklet
