实现这个动画效果用到了interpolator属性,这样就能让一些控件产生自定义的抖动效果

这是用作interpolator的文件,用来做动画循环

cycle.xml

<?xml version="1.0" encoding="utf-8"?>
<cycleInterpolator
xmlns:android="http://schemas.android.com/apk/res/android"
android:cycles="20" />

x轴抖动:

<?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="1000"
android:interpolator="@anim/cycle" />

y轴抖动:

<?xml version="1.0" encoding="utf-8"?>
<translate
xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="1000"
android:fromYDelta="0"
android:interpolator="@anim/cycle"
android:toYDelta="10" >
</translate>

有角度的抖动:

<?xml version="1.0" encoding="utf-8"?>
<rotate
xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="180"
android:fromDegrees="-2"
android:pivotX="100%"
android:pivotY="100%"
android:repeatCount="infinite"
android:repeatMode="reverse"
android:toDegrees="2" />
