In this paper, we investigate the agegraphic dark energy (ADE) model byincluding the sign-changeable interaction between ADE and dark matter innon-flat universe. It is shown that the interaction induces an energy flow ofwhich the direction is first from dark matter to ADE and then from ADE to darkmatter. The phase space analysis is made and the critical points are found, oneof which is the accelerated scaling attractor solution. So, the coincidenceproblem can be alleviated. Furthermore, we show the evolution of the densityparameter $\Omega$, the deceleration parameter $q$ and the equation of state(EoS) parameter $w_{d}$ of ADE. We also find that our model is consistent withthe observational data.
