Translation Animation
WoWoTranslationAnimation changes the translation x, y values of a view with methods setTranslationX and setTranslationY. Different with WoWoPositionAnimation, the x, y values here is relative to the original ones.
viewAnimation.add(WoWoTranslationAnimation.builder().page(0)
.fromX(view.getTranslationX()).toX(-screenW / 2 + radius)
.fromY(view.getTranslationY()).toY(-screenH / 2 + radius)
.ease(ease).build());
Similar to WoWoPositionAnimation, the animation-adding job is better to do after when the views-layout happened. So in the WoWoTranslationAnimationActivity as a demo, I put the code in onWindowFocusChanged methods:
@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
addAnimations();
}
private void addAnimations() {
// Prevent duplicate adding
if (animationAdded) return;
animationAdded = true;
// Add animations
}
WoWoTranslationAnimation extends XYPageAnimation and PageAnimation. Check more implementation details in its superclasses.
