Android ObjectAnimatorSet XML轉換爲JAVA代碼

Question

這些是我在xml中設置的animator，我想轉換爲java代碼，但是我不知道如何在「AnimatorSet」中設置「AnimatorSet」？

<?xml version="1.0" encoding="utf-8"?> 

<set xmlns:android="http://schemas.android.com/apk/res/android" 
android:ordering="sequentially"> 
    <set> 
     <objectAnimator 
      android:duration="50" 
      android:propertyName="scaleX" 
      android:valueFrom="1.0" 
      android:valueTo="0.8" /> 
     <objectAnimator 
      android:duration="50" 
      android:propertyName="scaleY" 
      android:valueFrom="1.0" 
      android:valueTo="0.8" /> 
    </set> 

    <set> 
     <objectAnimator 
      android:duration="50" 
      android:propertyName="scaleX" 
      android:valueFrom="0.8" 
      android:valueTo="1.1" /> 
     <objectAnimator 
      android:duration="50" 
      android:propertyName="scaleY" 
      android:valueFrom="0.8" 
      android:valueTo="1.1" /> 
    </set> 
</set>

首先，你必須創建一個AnimatorSet一起玩動畫，然後添加兩個ObjectAnimator到AnimatorSet，像這樣：

AnimatorSet animatorSet = new AnimatorSet(); 
    animatorSet.playTogether(
      ObjectAnimator.ofFloat(view, "scaleX", 1, 0.8f, 1.1f), 
      ObjectAnimator.ofFloat(view, "scaleY", 1, 0.8f, 1.1f) 
    ); 
animatorSet.setDuration(1000); 
animatorSet.start();
