We propose to measure the decay asymmetry parameters in the hadronic weak decays of singly charmed.baryons, such as Lambda_c->Lambda pi+, Sigma0 pi+, p Kbar, Xi_c0->Xi- pi+ and Omega_c.0->Omega-pi+.. The joint angular formulae for these processes.are presented, and are used to extract the asymmetry parameters in e+e- annihilation data. Base on the current.Lambda_c+ data set collected at BESIII, we estimate the experimental sensitivities to measure the parameters alpha_{Lambda pi+} for.Lambda_c->Lambda pi+, alpha_{Sigma+ pi0} for Lambda_c+->Sigma^+ pi0 and alpha_{Sigma0pi+} for Lambda_c->Sigma0 pi+.
