用动画的TextView的颜色变化（卡拉OK） [英] Change color of textview using Animation (Karaoke)

问题描述

我需要在我的应用程序来模拟一个卡拉OK。

I need to simulate a karaoke in my application.

我也希望用户更改着色每个单词（制作卡拉OK \\较慢更快）的期限。

I also want the user to change the duration of coloring each word (Making the karaoke slower \ faster).

我读过这个解决方案：

I've read this solution: SOLVED - How to make Dynamic change of TextVIew and UI in general?

可以此解决方案通过动画，这是$ P $在API 4.0 psented被取代？如何能做到？

Can this solution be replaced by Animation that was presented in API 4.0 ? How can it be done ?

推荐答案

我从来没有做过，所以我没有任何code真的对你。

I have never done it so I don't have any code for you really.

但我认为你可以使用3 ofInt ValueAnimator对象从0-255去重新present RGB值。

But I think you could use 3 ofInt ValueAnimator object to go from 0-255 to represent rgb values.

然后在每一个步骤，你可以在RGB值传递给 Col​​or.rgb（R，G，B）; 的，这个结果传递给 TextView.setTextColor（INT颜色）;

Then at each step you could pass in the rgb values to Color.rgb(r,g,b); And pass the result of that to TextView.setTextColor(int color);
