I'm trying to animate a set of views vertically in an RecyclerView.Adapter, the animation works well using android:clipChildren="false", android:clipToPadding="false" and viewHolder.linear.postInvalidate(), but the ClickListener does not work after animation ends. I'm using ObjectAnimator because I read this link Android Animation - Button stays clickable Some code @Override public void onBindViewHolder(final TViewHolder viewHolder, int i) { viewHolder.flGroupButtons.postInvalidate(); viewHolder.iv1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //not

Android应用资源---动画资源(Animation Resources)

有两种类型的动画资源: 属性动画 在设定的时间内,通过修改与 Animator 类相关的对象的属性值来创建一个动画。 视图动画 有两种类型的视图动画框架 补间动画( Tween animation ):通过执行通过执行一系列的与 Animation 类相关的单一图片的转换来创建动画。 帧动画( Frame animation ):通过显示与 AnimationDrawable 类的顺序相关的图片序列来创建动画。 属性动画 动画被定义在要修改的目标对象属性的 XML 中,如设定时间内的背景色或 alpha 值。 文件位置( FILE LOCATION ): res/animator/filename.xml ,文件名被用作资源 ID 。 被编译的资源类型( COMPILED RSOURCE DATATYPE ): 资源要指向 ValueAnimator 、 ObjectAnimator 或 AnimatorSet 类型 资源引用( RESOURCE REFERENCE ): 在 Java 代码中: R.animation.filename 在 XML 文件中: @[package:]animator/filename 语法( SYNTAX ): < set android:ordering=["together" | "sequentially"]> < objectAnimator

回想起前年左右,自己去社招的时候,一连串下来问了好多现在都是历历在目。回想起以前才觉得 纸上得来终觉浅,绝知此事要躬行 所有的面试题答案并不是百分百的标准,要靠你自己的感悟和有自己的想法,才能独树一帜脱颖而出的。所有仅供参考 所有的都在这个PDF中有所汇总,983页花了几十个小时整理出来的。还是比较全面的有Android,Java小知识,到性能优化.线程.View.OpenCV.NDK.大厂面试,算法等等,大家可以联系我看看对自身有没有用 (更多完整项目下载。未完待续。源码。图文知识后续上传github。) 可以联系我获取完整PDF ( VX:mm14525201314 ) 1丶如何进行单元测试,如何保证 App 稳定 ? 要测试 Android 应用程序,通常会创建以下类型自动单元测试 本地测试: 只在本地机器 JVM 上运行,以最小化执行时间,这种单元测试不依赖于 Android 框架,或者即使有依赖,也很方便使用模拟框架来模拟依赖,以达到隔离 Android 依赖的目的,模拟框架如Google 推荐的 Mockito; 检测测试: 真机或模拟器上运行的单元测试,由于需要跑到设备上,比较慢,这些测试可以访问仪器(Android 系统)信息,比如被测应用程序的上下文,一般地,依赖不太方便通过模拟框架模拟时采用这种方式; 注意: 单元测试不适合测试复杂的 UI 交互事件 App

How to resume and pause ObjectAnimator in Android for API Levels below 19?

穿精又带淫゛_ 提交于 2019-12-04 04:17:29
I am aware that API level 19 supports pause() and resume() on ObjectAnimators. But in my project at API level 14, I have an ObjectAnimator which is applied to an Image view to rotate it. I want to pause the animation provided by the ObjectAnimator on touch and resume it from the place where the image view was (before touch down). So I attempted to save the current play time and cancel the object animator on my stopAnimation() function. private void stopAnimation(){ currentTime = mGlobeAnimator.getCurrentPlayTime(); mGlobeAnimator.cancel(); } In the startAnimation() function, I recreate the

一、Tween动画 1、特点: 1.只是实现了简单的渐变,平移,拉伸,缩放; 2.Tween动画实现完成以后,该动画会恢复原状,自身属性并没有发生任何改变,动画的形成是通过父布局改变了其位置或渐变度,从而来改变其本身在短时间内的属性 3.此动画的形成是依赖于其父布局的,其属性没有发生任何改变 2、在Tween动画中所有动画的父类是Animation。 3、动画的渐变 /** * 渐变 / private void alpin(){ / * * 第一个参数:表示开始的透明度 * 第二个参数:表示结束的透明度 * 透明度的范围是0-1;1表示完全不透明;0表示完全透明 / Animation animation=new AlphaAnimation(0,1); animation.setDuration(3000); //设置动画重复的次数 animation.setRepeatCount(5); / * * Animation.REVERSE:重复的时候进行反转 * Animation.RESTART:每次执行都重新开始 / animation.setRepeatMode(Animation.RESTART); animation.setAnimationListener(new Animation.AnimationListener() { / * * 动画开始执行的时候的一个回调

Change multiple properties with single ObjectAnimator?

问题 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

Stop AnimatorSet of ObjectAnimators in Android

允我心安 提交于 2019-12-03 09:38:20
问题 Im trying to stop the animation of an ImageView when a button is clicked. The animation I am using is an AnimatorSet consisting of 5 ObjectAnimators ... The problem is that I can't figure how to stop and clear this animation from the ImageView when the button is clicked as btn.clearAnimation() obviously doesn't work. Thank you for your help. 回答1: You should be able to call animatorSet.cancel() to cancel the animation. Here's an example that cancels the animation 5 seconds after it starts:
