Thanks Mark
So my code is complete but I have an issu when I want to choice the
icon on getView().
I want to choice my icon like thre following code. But I have to use
the oClient object to find Flag.
oClient is on TabVoicemail class.
But IconicAdapter is a class and I can't touch oClient.
So I try to touch oClient because IconicAdapter is into my
TabVoicemail class.
but I have a : 08-11 12:00:02.176: ERROR/AndroidRuntime(1169):
java.lang.NullPointerException
My java code :

So my question is How I can use my oClient into my IconicAdapter
class without pass Oclient as parameter.
Just information: my line code " oClient.getMsg(i).getFlag() " run
into my TabVoicemail class and have no error.
