problem with a ListView

I am stuck with a aesthetic issue with List Views for several days, and I can't find any solution.

So, as a very experimented programmer as I am, I'm gonna use a very advanced technique : ask for any solution for this problem publicaly !

Usually, some seconds after warning the whole planet, the programmer finds the solution on his own !

Here's my problem :

I have a ListActivity, with my list of High Scores :

But the problem arises when I click on the listView to make it scroll :

It is less sexy this way ( and also quite less readable ).

I tried to juggle with some parameters, like enable / clickable / focusable / focusableInTouchMode (that I just understood from the http://android-developers.blogspot.com/ site). I also tried the listSelector or the background parameters ; but with no success...

I'm sure there is something I miss there, but what...

( Note : I have now found the solution here )
