How to change color of a single item in RecyclerView?

Question

I have a problem with setting color from resources for an item in RecyclerView. I've tried this two methods but none works. Any ideas what am I doing wrong?

holder.alert.setTextColor(R.color.alertGreen);
holder.alert.setTextColor(getResources().getColor(R.color.alertGreen));

Answer 1

Use ContextCompat to get color.

holder.alert.setTextColor(ContextCompat.getColor(context, R.color.alertGreen));

Answer 2

To update the color for the Single item you can follow below technique,

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {

// Green color to set to specific item in the view [By referencing the position you need to handle the view]
int color1 = ContextCompat.getColor(context, R.color.alertGreen));

// Red color to set to remaining Views
int color2 = ContextCompat.getColor(context, R.color.alertRed));

     if (position == 1) {
       holder.alert.setTextColor(color1);
     } else {
       holder.alert.setTextColor(color2);
     }
}
