[안드로이드] 서서히 사라지는 효과 내기 - Animation

정의 ---------------------------------------
Animation a = new TranslateAnimation(0.0f,

parent.getWidth() - target.getWidth() - parent.getPaddingLeft() - parent.getPaddingRight(), 0.0f, 0.0f);

 

//에니메이션 설정

a.setDuration(1000);

a.setStartOffset(300);
a.setRepeatMode(Animation.RESTART);
a.setRepeatCount(Animation.INFINITE);

 

3. 에니메이션별 interpolator 설정

미리 정의된 안드로이드 에니메이션 설정을 얻는다.

a.setInterpolator( AnimationUtils.loadInterpolator( this, android.R.anim.식별자) );

 

- 점점빠르게 : accelerate_interpolator

- 점점 느리게 이동 : decelerate_interpolator

- 위 둘을 동시에 : accelerate_decelerate_interpolator

- 시작위치에서 조금 뒤로 당겼다 이동 : anticipate_interpolator

- 도착위치를 조금 지나쳤다가 도착위치로 이동 : overshoot_interpolator

- 위 둘을 동시에 : anticipate_overshoot_interpolator

- 도착위치에서 튕김 : bounce_interpolator
