Android动画一个接一个

Question

我在 TextView 上有两个 TranslateAnimation，我希望它们一个接一个地执行。但是，通过使用下面的代码，只会执行第二个。

我该如何解决这个问题？

TranslateAnimation animation = new TranslateAnimation(
    Animation.ABSOLUTE, 0.0f, Animation.ABSOLUTE, 0.0f,
    Animation.ABSOLUTE, 0.0f, Animation.ABSOLUTE, -150.0f);
animation.setDuration(200);
wave.startAnimation(animation);

TranslateAnimation animation1 = new TranslateAnimation(
    Animation.ABSOLUTE, 0.0f, Animation.ABSOLUTE, 0.0f,
    Animation.ABSOLUTE, 150.0f, Animation.ABSOLUTE, 0.0f);
animation1.setDuration(200);
wave.startAnimation(animation1);

Answer 1

将它们链接在一起 Animation Set

AnimationSet as = new AnimationSet(true)
TranslateAnimation animation = new TranslateAnimation(
Animation.ABSOLUTE, 0.0f, Animation.ABSOLUTE, 0.0f,
Animation.ABSOLUTE, 0.0f, Animation.ABSOLUTE, -150.0f);
animation.setDuration(200);
as.addAnimation(animation);

TranslateAnimation animation1 = new TranslateAnimation(
Animation.ABSOLUTE, 0.0f, Animation.ABSOLUTE, 0.0f,
Animation.ABSOLUTE, 150.0f, Animation.ABSOLUTE, 0.0f);
animation1.setDuration(200);
animation1.setStartOffset(200);
as.addAnimation(animation1);

wave.startAnimation(as);
