你如何修改HSV值（hsv [1]，hsv [1]，hsv [2]）？

I have a class that extends View. The class is created in a fragment that contains a seekbar. Using the code below, I pass the seekbar value to the view class via seekbar.setSatVal(value).

我有一个扩展View的类。该类在包含搜索条的片段中创建。使用下面的代码,我通过seekbar.setSatVal(value)将搜索栏值传递给视图类。

public void setSatValue(float value){
        mValue = value/100; //seekbar goes from 0 to 100
        setVal(mValue);
    }

I then get the RGB values from the bitmap I passed (not shown in code) and convert them to HSV values.

然后我从我传递的位图中获取RGB值(未在代码中显示)并将它们转换为HSV值。

int mPixel = mBitmap.getPixel(1,1);

            hsv = new float[3];

            r = Color.red(mPixel);
            g = Color.blue(mPixel);
            b = Color.green(mPixel);

            Color.RGBToHSV(r, g, b, hsv);

I know that I have to use Color.HSVToColor to convert HSV values back to color.

我知道我必须使用Color.HSVToColor将HSV值转换回颜色。

How do I modify the HSV values? hue: hsv[0], saturation: hsv1, value: hsv[2] I have read through the color documentation and know the values each takes.

如何修改HSV值? hue:hsv [0],饱和度:hsv1,值:hsv [2]我已阅读了颜色文档并了解了每个值。

As suggested, this should work as I have implemented the same in Android -

正如所建议的那样,这应该可行,因为我在Android中实现了相同的功能 -

float[] hsv = new float[3];
Color.RGBToHSV(red,green,blue,hsv);
hsv[0]=hue; //hue 
hsv[1]=sat; //saturation 
hsv[2]=val; //brightness

hue sat and val can be any user defined or calculated values.

hue sat和val可以是任何用户定义或计算的值。
