  Using the full data sample collected with the Belle detector at the KEKB
asymmetric-energy $e^+e^-$ collider, we have searched for CP violation of
charmed mesons in $D^+\rightarrow K^0_S\pi^+$ and $D^0\rightarrow h^+h^-$
decays, where $h$ denotes $K$ and $\pi$. We observe evidence for CP violation
in $D^+\rightarrow K^0_S\pi^+$ decay with 3.2 standard deviations away from
zero, $(-0.363\pm0.094\pm0.067)%$, while the asymmetry is consistent with the
expected CP violation due to the neutral kaon in the final state. No evidence
for CP violation in $D^0\rightarrow h^+h^-$ is observed with
$A^{KK}_{CP}=(-0.32\pm0.21\pm0.09)%$ and
$A^{\pi\pi}_{CP}=(+0.55\pm0.36\pm0.09)%$. The CP asymmetry difference between
$D^0\rightarrow K^+K^-$ and $D^0\rightarrow\pi^+\pi^-$ decays is also measured
with $\Delta A^{hh}_{CP}=(-0.87\pm0.41\pm0.06)%$, which is 2.1 standard
deviations away from zero and supports recent LHCb and CDF measurements.
