差不多一年前在自己的项目中用过这效果,虽然很简单,但还是写写。
1、首先在你的res目录下新建anim子目录,并在anim目录下新建两个文件:
(1)shake.xml文件(位移/平移:translate),设置起始的位移范围、效果时间、循环次数

<? xml version = "1.0" encoding = "utf-8" ?> < translate xmlns:android = "http://schemas.android.com/apk/res/android" android:fromXDelta = "0" android:toXDelta = "10" android:duration = "500" android:interpolator = "@anim/share_cycle" > <!--. fromXDelta:x轴起点抖动位置 toXDelta:x轴终点抖动位置 duration:循环播放的时间 interpolator:循环不放设置(次数) --> </ translate > |
(2)cycle.xml文件,控制循环次数

<? xml version = "1.0" encoding = "utf-8" ?> < cycleInterpolator xmlns:android = "http://schemas.android.com/apk/res/android" android:cycles = "2" > <!--. 循环次数 --> </ cycleInterpolator > <!--. 循环播放 --> |
最后给你的控件设置改动画属性
Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);
ivShake.startAnimation(shake);
这里ivShake是ImageView,就是这么简单。
2、个人碰到一个问题就是在Activity实现监听中添加动画效果第一次没有反应,不知道为什么
补充知识:Android 抖动提示动画
左右抖动

ObjectAnimator animator = ObjectAnimator.ofFloat(textView, "translationX" , 0 , 100 , - 100 , 0 ); animator.setDuration( 200 ); animator.start(); |
