android:动画颜色从颜色到颜色的变化 [英] android: Animate color change from color to color

问题描述

假设我有两种颜色，我需要创建一个实时动画来快速从一种颜色切换到另一种颜色.

Assuming I have two colors, and I need to create a real time animation that fastly switches from a color to another.

我尝试只增加十六进制颜色，直到到达另一个，但这给出了一个非常糟糕的动画，因为它显示了许多不相关的颜色.

I tried just to increment the color hexadecimal until I reach the other, but that gave a really bad animation as it showed lots of unrelated colors.

我正在使用 setColorFilter(color, colorfilter) 来更改图像视图的颜色.

I am using setColorFilter(color, colorfilter) to change the color of an imageview.

改变色调会给我最好的视觉效果吗?如果是这样，我该如何将其更改为纯色?

Changing the HUE will give me the best visual results? If so, how can I change it for a solid color?

解决方案:我通过递归变换色调解决了

SOLUTION: I solved it by recursively shifting hue

private int hueChange(int c,int deg){
       float[] hsv = new float[3];       //array to store HSV values
       Color.colorToHSV(c,hsv); //get original HSV values of pixel
       hsv[0]=hsv[0]+deg;                //add the shift to the HUE of HSV array
       hsv[0]=hsv[0]%360;                //confines hue to values:[0,360]
       return Color.HSVToColor(Color.alpha(c),hsv);
    }
