Cardview - Set different background color for each element

Question

I'm working on improving my RecyclerView and CardView skills as I'm new to this.

I created a CardView layout and RecyclerView layout and then Layout Manager and View adapter, minimum that's required to get the app looking like this -

What I want to do is - I want different background colors for every element. For example - Red for "Froyo" , Amber "Gingerbread" and so on.

Any way I can do it?

Also, I want elements separated by 1dp

Thank you

Answer 1

Yes you can do that in RecyclerViews onBindViewHolder method by referring to each card by it's position.

 public void onBindViewHolder(MyViewHolder holder, int position) {
    if(position==1)
       holder.view.setBackgroundColor(Color.RED);
    else if(position==2)
       holder.view.setBackgroundColor(Color.parseColor("#amberColorCode")); //and so on..
}

here view is your TextView or any other view which you are using as RecyclerView row item.

For separating element my 1 density pixel: Modify your widget.Card View and specify the required space in your relative layout.[Change your widget.card view accordingly] https://i.stack.imgur.com/nSJ7W.png
