推荐答案

1）30s是一个真的，很长的时间，几乎没有任何用户会等待看到结束。

1) 30s is a really, really long time, hardly any users would wait to see the end of it.

2）请参阅使用ObjectAnimator 进行动画。像 ObjectAnimator.ofInt（textView，textColor，Color.GREEN，Color.RED）应该做你想要的。然而，请注意，转换将是线性的，并且将经历很多中间颜色。直到它命中＃FF0000 。你当然可以指定中间的点，但一般线性的颜色转换（在RGB）是不漂亮。

2) See Animating with ObjectAnimator. Something like ObjectAnimator.ofInt(textView, "textColor", Color.GREEN, Color.RED) should do what you want. Note, however, that the transition will be linear and will go through a lot of intermediary colors. until it hits #FF0000. You can of course specify the points in the middle but in general linear color transitions (in RGB) are not pretty.
