  In ALICE, open heavy-flavour production is studied through the measurements
of the leptons (electrons and muons) from heavy-flavour hadron decays at
central and forward rapidity and via the reconstruction of D-meson hadronic
decays at mid-rapidity. An overview of the open heavy-flavour production with
ALICE in pp ($\sqrt{s}$ = 2.76 TeV and 7 TeV), p--Pb ($\sqrt {s_{\rm NN}}$ =
5.02 TeV) and Pb--Pb ($\sqrt {s_{\rm NN}}$ = 2.76 TeV) collisions will be
presented. We will discuss the production cross sections, modifications of the
transverse momentum distributions, azimuthal anisotropic emissions and
correlations with hadrons in comparison with various theoretical predictions.
