The nucleon self-energy obtained from the Dirac Brueckner-Hartree-Fock calculation is parametrized by introducing density-dependent coupling constants of isoscalar mesons in the relativistic Hartree-Fock (RHF) approach. The RHF calculations with density-dependent coupling constants not only reproduce the nuclear matter saturation properties, but also provide a good starting point to study finite nuclei properties. The relativistic density-dependent Hartree-Fock (RDHF) approach contains the features of the relativistic {ital G} matrix and in the meantime simplifies the calculation. The ground state properties of spherical nuclei calculated in the RDHF are in good agreement with the experimental data. The contribution of isovector mesons {pi} and {rho}, especially the contribution of the tensor coupling of {rho} meson, are discussed in this paper.
