ObjectAnimator 簡易物件動作設定

public void setViewAnimation(View v)
{
    AnimatorSet ans = new AnimatorSet();
    ObjectAnimator[] ann = new ObjectAnimator[2];
    ann[0] = ObjectAnimator.ofFloat(v,"scaleX",0,1);
    ann[1] = ObjectAnimator.ofFloat(v,"scaleY",0,1);
    ans.playTogether(ann);
    ans.setDuration(1000);
    ans.start();
}

可動畫屬性介紹

alpha:     透明度
scaleX:    X 軸縮放
scaleY:    Y 軸縮放
rotation:    Z 軸旋轉
rotationX:   X 軸旋轉
rotationY:   Y 軸旋轉
translationX: X 軸移動
translationY: Y 軸移動

小 -> 放大 -> 縮小

ann[0] = ObjectAnimator.ofFloat(v,"scaleX",0,1.5,1);
ann[1] = ObjectAnimator.ofFloat(v,"scaleY",0,1.5,1);

這個動作可以從最小變到1.5倍之後再變回原始大小.
