Within the QCD factorization approach, we study the CP violations in 
and decays. We find the experimental data of the localized CP asymmetry in decays in the region 
and 
can be explained by the interference of two intermediate resonances, 
and 
when the parameters in our interference model are in the allowed ranges, i.e. the relative strong phase 
and the end-point divergence parameters 
and 
. With the obtained allowed ranges for 
and 
, we obtain the predictions for the CP asymmetry parameter 
and the branching fraction 
for 
decay modes.
