如何以编程方式更改 textView 的颜色以在 Android Studio 上形成良好的对比？

Question

i'm wondering if there is a fonction that takes an Color int and return the "Opposite color "(between Black and White)

I would use it in a recyclerView Adapter, with a background color that is customizable.

Thank you, you devs:)

Answer 1

I quickly thought about creating my own function, but I would appreciate being aware of any official method:)

I share with you what I've written, it's working fine.

private int createContrastColor(int color) {

    int red = Color.red(color);
    int green = Color.green(color);
    int blue = Color.blue(color);

    if (red > 125 && green > 125 && blue > 125){
        return Color.Black;
    } else {
        return Color.White;
    }

}
