"Does the XA2 has the meter needle in viewfinder like that of the XA?"
-no it has no exposure info.

I have both a XA2 and XA in my hands right now. The XA2 gives about the same shutter speed as the XA when set on f4. (It seems the XA2 prefers wide-open unless in really bright light)

It seems everyone agrees that your camera is under-exposing. Quite a bit from the look of it. Maybe 2 stops.
