Answer 1

Simple using Kotlin.

First, set the animations:

private fun setAnimations() {
    // in anim
    val inAnim = AlphaAnimation(0f, 1f)
    inAnim.duration = 600
    flipperView.inAnimation = inAnim

    // out anim
    val outAnim = AlphaAnimation(1f, 0f)
    outAnim.duration = 600
    flipperView.outAnimation = outAnim

}

And to flip (between two views) just call this function:

fun onSendClick(view: View) {
    viewFlipper.displayedChild = if(flipperView.displayedChild == 0) 1 else 0
}
