NH4I + H2O --> NH4OH + H+ + I-
HI being a strong acid, remains almost wholly ionised as H+ & I- ion
NH4OH being a weak base so you have some more H+ left therefore it is acidic solution. (problem: NH4OH is not an exsisting compound, most of it will react with the strong acid H+ and the remainig will be fully ionized into NH4+)
Added:
(problem solved: not using NH4OH as it is annon-exsisting compound)
NH4I will completely dissolve in ammonium and iodide ions:
NH4I --> I- + NH4+
of which I- is neutral and NH4+ is quite a weak acid (pKa = 9.25). (The molar standard solution of NH4I will have pH approx. 4.6)
It's an acid, it is a strong acid along with most other hydrogen halides..
Ammonia solution is basic.
