List Animation

List Animation is used to add animations to the appearance of list items.

Animation Types

You can quickly set several built-in animation types provided by BRV using the following function:

fun setAnimation(animationType: AnimationType)

The available animation types are specified using the AnimationType enum:

Enum	Animation Description
ALPHA	Fade-in animation
SCALE	Scale animation
SLIDE_BOTTOM	Slide-in from the bottom
SLIDE_LEFT	Slide-in from the left
SLIDE_RIGHT	Slide-in from the right

Custom List Animation

If the default animations are not sufficient for your needs, you can customize the desired animation effect by referring to the built-in subclasses of ItemAnimation.

fun setAnimation(itemAnimation: ItemAnimation)

Here is an example using the source code of AlphaItemAnimation:

class AlphaItemAnimation @JvmOverloads constructor(private val mFrom: Float = DEFAULT_ALPHA_FROM) : ItemAnimation {

    override fun onItemEnterAnimation(view: View) {
        ObjectAnimator.ofFloat(view, "alpha", mFrom, 1f).setDuration(300).start() // Fade-in animation
    }

    companion object {

        private val DEFAULT_ALPHA_FROM = 0f // Initial opacity
    }
}
