  Azimuthal correlation studies of heavy-flavour particles with charged
particles in p--Pb collisions can give an insight into the cold nuclear matter
effects \cite{Andronic:2015wma} on heavy-quark production and hadronization
into heavy-flavour jets. Multiplicity-dependent measurements of angular
correlations of heavy-flavour particles with charged hadrons allow us to
investigate the collective behavior of the system and the initial state effects
on heavy flavour hadron production. In addition, they can reveal possible
modifications of the heavy-quark fragmentation and hadronization at different
multiplicities. We present ALICE measurements of azimuthal correlations of
prompt D-mesons with charged hadrons as a function of the multiplicity in p--Pb
collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02TeV. Moreover, the elliptic flow
($v_2$) of heavy-flavour hadron decay electrons in high-multiplicity p--Pb
collisions at $\sqrt{s_\mathrm{NN}}$= 5.02 TeV, obtained using correlations
with charged particles, is reported.
