[ Android / Kotlin ] 안드로이드 액티비티 전환 애니메이션

res파일 아래에 animation 폴더 생성하기

 

왼쪽 -> 오른쪽 / 오른쪽 -> 왼쪽으로 전환

액티비티 전환시 startActivity() 이후 overridePendingTransition

overridePendingTransition(시작할때 애니메이션, 끝날때 애니메이션)

 

---

액티비티가 많아지면 사용하는데 불편한 점이 많기 때문에, Kotlin의 Extension기능을 사용할 수 있음

Extenstion 파일을 하나 만들어서 activity 확장함수를 만들 수 있습니다.

fun Activity.slideLeft() {
    overridePendingTransition(R.anim.slide_left_enter, R.anim.slide_left_exit)
}

fun Activity.slideRight() {
    overridePendingTransition(R.anim.slide_right_enter, R.anim.slide_right_exit)
}

fun Activity.slideUp() {
    overridePendingTransition(R.anim.slide_up_enter, R.anim.slide_up_exit)
}

fun Activity.slideDown() {
    overridePendingTransition(R.anim.slide_down_enter, R.anim.slide_down_exit)
}
