Get Color from resource id integer gives error

Question

I have created a custom view which accepts background color resid and shadow color resId. But when i convert resource ids to store them in a int variable. It give error as

Expected a color resource id (R.color.) but received an RGB integer 

Following are my setter methods

    @Override
    public void setBackgroundColor(@ColorRes int backgroundResId) {
        this.backgroundColor = ContextCompat.getColor(context, backgroundResId);
    }

    public void setShadowColor(@ColorRes int shadowColorId) {
        this.shadowColor = ContextCompat.getColor(context, shadowColorId);
    }

Same error is shown when used

public void setBackgroundColor(@ColorRes int backgroundResId) {
    this.backgroundColor = context.getResources().getColor(backgroundResId);
}

Answer 1

I suppose you pass wrong argument in your method setBackgroundColor . You should use it in that way:

//some code
setBackgroundColor(R.color.colorPrimary)
//some code
