[Java] [Android] 控件动画

我个人喜欢这么写

ObjectAnimator oa1 = ObjectAnimator.ofFloat(button1,View.TRANSLATION_X,0,1000,0);
ObjectAnimator oa2 = ObjectAnimator.ofFloat(button1,View.TRANSLATION_Y,0,2000,0);
oa1.setDuration(1000);
oa2.setDuration(1000);

AnimatorSet as = new AnimatorSet();
as.playTogether(oa1,oa2);
as.start();

当然也可以手动指定

ObjectAnimator oa3 = new ObjectAnimator();
oa3.setTarget(button1);
oa3.setDuration(1000);
oa3.setProperty(View.ALPHA);
oa3.setFloatValues(1,0,1);
oa3.start();

TranslateAnimation a1 = new TranslateAnimation(1000,0,0,2000);
a1.setDuration(1000);
button1.startAnimation(a1);
