在res文件夹下创建一个animator文件夹
ValueAnimator
新建一个value.xml文件
<?xml version="1.0" encoding="utf-8"?>
<animator xmlns:android="http://schemas.android.com/apk/res/android"
android:valueFrom="0.1f"
android:valueTo="1f"
android:valueType="floatType"
android:duration="3000"
/>
ObjectAnimator
新建一个object.xml文件
<?xml version="1.0" encoding="utf-8"?>
<objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
android:propertyName="backgroundColor"
android:repeatCount="infinite"
android:duration="300"
android:repeatMode="reverse"
android:valueFrom="#456412"
android:valueTo="#780054"
/>
AnimatorSet
新建一个animatorSet.xml文件
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:ordering="together">
<objectAnimator
android:duration="500"
android:valueType="floatType"
android:propertyName="x"
android:valueFrom="0"
android:valueTo="300dp"
/>
<set android:ordering="sequentially">
<objectAnimator
android:propertyName="alpha"
android:valueFrom="0"
android:valueTo="1f"
android:valueType="floatType"
android:duration="500"
/>
<objectAnimator
android:propertyName="rotation"
android:valueType="floatType"
android:valueFrom="-90"
android:valueTo="180"
android:duration="1000"
/>
</set>
</set>
在代码中使用
ObjectAnimator oa13 = (ObjectAnimator) AnimatorInflater.loadAnimator
(this,R.animator.object);
ValueAnimator va4 = (ValueAnimator)AnimatorInflater.loadAnimator
(this,R.animator.value);
AnimatorSet set3 = (AnimatorSet) AnimatorInflater.loadAnimator
(this,R.animator.animatorSet);
PS.属性动画是一个很强大的动画库,卫星菜单、抽屉等效果都可以通过属性动画来实现,这些只是最基本的使用方法而已。
再PS. 如果想进一步深入了解属性动画请移步启舰、郭霖、张鸿洋、任玉刚等大神的博客
