Both the resonance and the nonresonance contributions are studied for the $B^-\\rightarrow K^-\\pi^+\\pi^-$ decay. The resonance contributions include those not only from $[\\pi\\pi]$ channels including $\\sigma(600)$, $\\rho^0(770)$ and $\\omega(782)$ but also from $[K\\pi]$ channels including $K^*(892)$, $K_0^*(1430)$, $K^*(1410)$, $K^*(1680)$ and $K_2^*(1430)$.
