Set background color of the material chip programmatically

You can set background color of material chip by following line (Kotlin)

chip.chipBackgroundColor = getColorStateList(/*your preferred color*/)

For Kotlin, you should use this:

chip.chipBackgroundColor = ColorStateList.valueOf(ContextCompat.getColor(context, R.color.yourColor))

For Java:

chip.setChipBackgroundColor(ColorStateList.valueOf(ContextCompat.getColor(context, R.color.yourColor)));
