In this paper, we first discuss the relation between $\text{VB}$-Courant algebroids and $\text{E}$-Courant algebroids, and we construct some examples of $\text{E}$-Courant algebroids. Then we introduce the notion of a generalized complex structure on an $\text{E}$-Courant algebroid, unifying the usual generalized complex structures on even-dimensional manifolds and generalized contact structures on odd-dimensional manifolds. Moreover, we study generalized complex structures on an omni-Lie algebroid in detail. In particular, we show that generalized complex structures on an omni-Lie algebra $\text{gl}\left( V \right)\oplus V$ correspond to complex Lie algebra structures on $V$.
