问题 I have a simple activity that shows an animation with ObjectAnimator.

问题 I'm working on animating an ImageView in Android (API 19), using ObjectAnimator . I've got everything working well, and it displays perfectly on a Galaxy S3, but on my Nexus 7 (2013 WiFi model) it's causing issues. The goal is to have an image do a full 360° rotation around its Y-axis using rotateY . However, on the Nexus 7, between 75° and 105°, the image disappears. My drawable was created from a PNG, and the relevant code is below. View: <ImageView android:id="@+id/login_logo" android

I am facing the following issue when I am using PropertyValuesHolder.ofFloat(....)

Android 动画 之 ObjectAnimator

android 3.0之后添加的一些动画 animator 中的 ObjectAnimator ： 补间动画能实现的: 1.alpha 透明度 //第一个参数为 view对象，第二个参数为 动画改变的类型，第三，第四个参数依次是开始透明度和结束透明度。 ObjectAnimator alpha = ObjectAnimator.ofFloat(text, "alpha", 0f, 1f); alpha.setDuration(2000);//设置动画时间 alpha.setInterpolator(new DecelerateInterpolator());//设置动画插入器，减速 alpha.setRepeatCount(-1);//设置动画重复次数，这里-1代表无限 alpha.setRepeatMode(Animation.REVERSE);//设置动画循环模式。 alpha.start();//启动动画。 2.scale AnimatorSet animatorSet = new AnimatorSet();//组合动画 ObjectAnimator scaleX = ObjectAnimator.ofFloat(text, "scaleX", 1f, 0f); ObjectAnimator scaleY = ObjectAnimator.ofFloat(text,

How to reset view to original state after using animators to animates its some properties?

由 耗尽温柔 提交于 2019-12-06 18:33:09
问题 I am using animators (ObjectAnimator) to animate few properties (scale, rotate) of a view. Target view is animating properly when ObjectAnimators are set to it. But there is an added requirement to get view to the original position (reset) after a while. I tried to cancel() the animator but it only cancels the animation and doesn't reset the view. Possible solution : creating another animator that does just opposite of the initial animator. Is there any other way to reset it ? 回答1: See the
