`void`	`setShowBorderOnlyBeforeL(boolean showBorderOnlyBeforeL)` the shadow elevation only work after L, so we provide a downgrading compatible solutions for android 4.x usually we use border, but the border may be redundant for android L+.
`void`	`setTopDividerAlpha(int dividerAlpha)` after config the border, sometimes we need change the alpha of divider with animation, so we provide a method to individually change the alpha
`void`	`setUseThemeGeneralShadowElevation()` use the shadow elevation from the theme
