We present the measurement of the absolute branching fractions of $B^{+} \to
X_{c\bar{c } } K^{+}$ and $B^{+} \to \bar{D}^{(\ast) 0} \pi^{+} $ decays, using a
data sample of $772\times10^{6}$ $B\bar{B}$ pairs collected at the
$\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy
$e^{+}e^{-}$ collider. Here, $X_{c\bar{c } }$ denotes $\eta_{c}$, $J/\psi$,
$\chi_{c0}$, $\chi_{c1}$, $\eta_{c}(2S)$, $\psi(2S)$, $\psi(3770)$, $X(3872)$,
and $X(3915)$. We do not observe significant signals for $X(3872)$ nor
$X(3915)$, and set the 90$\%$ confidence level upper limits: ${\cal B}(B^{+}
\to X(3872) K^{+} )<2.7 \times 10^{-4}$ and ${\cal B}(B^{+} \to X(3915) K^{+}
)<2.9 \times 10^{-4}$. These represent the most stringent upper limit for
${\cal B}(B^{+} \to X(3872) K^{+} )$ to date and the first measurement for
${\cal B}(B^{+} \to X(3915) K^{+} )$. The measured branching fractions for
$\eta_{c}$ and $\eta_{c}(2S)$ are the most precise to date: ${\cal B}(B^{+} \to
\eta_{c} K^{+} )=(12.3\pm0.8\pm0.7) \times 10^{-4}$ and ${\cal B}(B^{+} \to
\eta_{c}(2S)K^{+}) =(4.9\pm1.1\pm0.3) \times 10^{-4}$ , where the first and
second uncertainties are statistical and systematic, respectively.
