TextColor更改为错误的一种

Question

I'm just trying to change textcolor in my recyclerview using this code ↓↓↓

itemView.resultTV.textColor = if (result >= 0) R.color.green else R.color.red

But it changes the color to light purple, which is neither basic color nor green nor red.

Any ideas?

Answer 1

you are using the resId of the color, while setTextColor expects the Color . You should use Resources to convert the R.color to color the resource represents

Answer 2

Try below code-

ContextCompat.getColor(context, R.color.green)

ContextCompat.getColor(context, R.color.red)

Answer 3

setTextColor期望可以由R.color提供的Color的“ int” 。“ 颜色代码 ”而不是resId。
