Set custom chipDrawable background to Chip

Using this code you can generate multicolor chip.

---

add this code in oncreate() or anywhere in function

// "i" is integer value and it will be unique for every chip. In my case I have put in chip in FOR loop that why "i" is there

Chip chip = (Chip) LayoutInflater.from(getActivity()).inflate(R.layout.item_content_lang_chip, null);
                chip.setText(contentLangModels.get(i).getContentDisplay());
                chip.setId(i);
chip.setChipBackgroundColor(buildColorStateList(getActivity(),"#1e61d5","#2e2e37"));


chipGrpContentType.addView(chip);

Add below function in your activity

 public ColorStateList buildColorStateList(Context context, String pressedColorAttr, String defaultColorAttr){
        int pressedColor = Color.parseColor(pressedColorAttr);
        int defaultColor = Color.parseColor(defaultColorAttr);

        return new ColorStateList(
                new int[][]{
                        new int[]{android.R.attr.state_checked},
                        new int[]{} // this should be empty to make default color as we want
                }, new int[]{
                pressedColor,
                defaultColor
        }
        );
    }

if you want change background color, you can try:

ChipDrawable chipDrawable = (ChipDrawable)chip.getChipDrawable();
chipDrawable.setChipBackgroundColorResource(R.color.colorPrimary);
