objectanimator

I have a pretty complex animation I need to code and I'm using a bunch of ObjectAnimators like the following: ObjectAnimator objectAnimator1 = ObjectAnimator.ofFloat(view, TRANSLATION_X, value).setDuration(BASE_DURATION * 2); ObjectAnimator objectAnimator2 = ObjectAnimator.ofFloat(view, TRANSLATION_Y, value).setDuration(BASE_DURATION * 2); Is it possible to group the X and Y translations into the same ObjectAnimator rather than creating a bunch of them then adding them all into an AnimatorSet? Thanks! PropertyValuesHolder pvhX = PropertyValuesHolder.ofFloat(TRANSLATION_X, value);

I'm trying to animate a slide-in/slide-out animation between Fragments . I know there're tons of similiar question out there on StackOverflow , but believe me - I tried all of them and none is working. Following my code (basically taken from similiar questions): Custom Layout public class SlidingFrameLayout extends FrameLayout { public SlidingFrameLayout(Context context) { super(context); } public SlidingFrameLayout(Context context, AttributeSet attrs) { super(context, attrs); } public float getXFraction() { final int width = getWidth(); if (width != 0) return getX() / getWidth(); else return

属性动画是Android 3.0加入的，为了弥补View动画的不足，但是Android 3.0以下虽然可以使用动画兼容库但是其本质依旧是View动画 View动画的不足之处 动画效果单一，旋转，平移，缩放 影像动画，并没有改变本身的参数，需要交互式view的时候暴露缺陷 作用对象局促于View上 ValueAnimator 类 先改变值，然后 手动赋值 给对象的属性从而实现动画；是 间接 对对象属性进行操作； ValueAnimator 对值进行操作 ValueAnimator.ofInt（int values） ValueAnimator.ofFloat（float values） ValueAnimator.ofObject（int values） 需要自定义估值器 ObjectAnimator 类 先改变值，然后 自动赋值 给对象的属性从而实现动画；是 直接对对象属性进行操作； ObjectAnimator 继承自ValueAnimator类，即底层的动画实现机制是基于ValueAnimator类 ObjectAnimator 类针对的是任意对象 & 任意属性值，并不是单单针对于View对象 如果需要采用ObjectAnimator 类实现动画效果，那么需要操作的对象就必须有该属性的set（） & get（） 同理，针对上述另外的三种基本动画效果，View

I'm trying to do a flipping card animation between two fragment like in --> Displaying Card Flip Animations by using: private void switchFragment(Fragment fragment) { FragmentManager fragmentManager = getSupportFragmentManager(); FragmentTransaction fragmentTransaction = fragmentManager .beginTransaction(); if ((fragment != null) && !(fragment.equals(currentFragment))) { if (transactionByMenu) { fragmentTransaction.setCustomAnimations(android.R.anim.fade_in, android.R.anim.fade_out); } else { fragmentTransaction.setCustomAnimations( R.animator.card_flip_right_in, R.animator.card_flip_right_out

How to increase the view height using Property Animations in Android? ObjectAnimator a = ObjectAnimator.ofFloat(viewToIncreaseHeight, "translationY", -100); a.setInterpolator(new AccelerateDecelerateInterpolator()); a.setDuration(1000); a.start(); The translationY actually moves the view not increase the height. How can I increase the height of the view? ValueAnimator anim = ValueAnimator.ofInt(viewToIncreaseHeight.getMeasuredHeight(), -100); anim.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() { @Override public void onAnimationUpdate(ValueAnimator valueAnimator) { int val =
