学习笔记|安卓中一些界面过场动画的实现属性动画|过场动画

一.在res的anim下写anim文件

代码引用

Intent intent = new Intent(activity, MainActivity.class); activity.startActivity(intent); activity.overridePendingTransition(R.anim.fade_in, com.jaydenxiao.common.R.anim.fade_out);

二.安卓5.x共享元素

Intent intent = new Intent(mContext, NewsDetailActivity.class); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { ActivityOptions options = ActivityOptions .makeSceneTransitionAnimation((Activity) mContext,view, AppConstant.TRANSITION_ANIMATION_NEWS_PHOTOS); mContext.startActivity(intent, options.toBundle()); } else {//让新的Activity从一个小的范围扩大到全屏 ActivityOptionsCompat options = ActivityOptionsCompat .makeScaleUpAnimation(view, view.getWidth() / 2, view.getHeight() / 2, 0, 0); ActivityCompat.startActivity((Activity) mContext, intent, options.toBundle()); }

这里，参数view是外界点击跳转的组件， AppConstant.TRANSITION_ANIMATION_NEWS_PHOTOS= "transition_animation_news_photos"
是需要共享的图片元素，所以对应的需要在目标界面展示效果的图片控件上加上共享元素属性

【学习笔记|安卓中一些界面过场动画的实现】ps:补上属性动画的一种写法

PropertyValuesHolder alpha = PropertyValuesHolder.ofFloat("alpha", 0.3f, 1f); PropertyValuesHolder scaleX = PropertyValuesHolder.ofFloat("scaleX", 0.3f, 1f); PropertyValuesHolder scaleY = PropertyValuesHolder.ofFloat("scaleY", 0.3f, 1f); ObjectAnimator objectAnimator1 = ObjectAnimator.ofPropertyValuesHolder(tvName, alpha, scaleX, scaleY); ObjectAnimator objectAnimator2 = ObjectAnimator.ofPropertyValuesHolder(ivLogo, alpha, scaleX, scaleY); AnimatorSet animatorSet = new AnimatorSet(); animatorSet.playTogether(objectAnimator1, objectAnimator2); animatorSet.setInterpolator(new AccelerateInterpolator()); animatorSet.setDuration(2000); animatorSet.addListener(new Animator.AnimatorListener() { @Override public void onAnimationStart(Animator animator) {}@Override public void onAnimationEnd(Animator animator) { MainActivity.startAction(SplashActivity.this); finish(); }@Override public void onAnimationCancel(Animator animator) {}@Override public void onAnimationRepeat(Animator animator) {} }); animatorSet.start();
