java - How to dynamically reference resources in the R.drawable folder in Android?

Question

I have the following code for my Adapter:

@Override
public void onBindViewHolder(GameViewHolder holder, int position) {
    final Games game = gameList.get(position);
    holder.awayTeamImageView.setBackgroundResource(R.drawable.fortyers);
}

The above works perfectly but I am hard coding the image that will be displayed. What I really need is to get the background image from the game list and I am looking to do something like this:

 holder.awayTeamImageView.setBackgroundResource(R.drawable.game.getaBackground());

But that causes an error

How can I dynamically set the imageView's background resource?

UPDATE:

I have attached a screenshot of the desired effect.

Each week the schedule will change so the list will always be different depending on the week selected.

Game constructor:

public Games(DataSnapshot game) {

    this.AwayTeam = game.child("AwayTeam").getValue().toString();
    this.AwayId = Integer.parseInt(game.child("AwayId").getValue().toString());

    this.HomeTeam = game.child("HomeTeam").getValue().toString();
    this.HomeId = Integer.parseInt(game.child("HomeId").getValue().toString());

    this.aBackground = game.child("aBackground").getValue().toString();
    this.hBackground = game.child("hBackground").getValue().toString();

}

Answer 1

Create a list of String that will contain the id of your drawables, keep them in the order synced with the position and then get the id as per the position from the list to pass while setting the drawable.

If it's something reused in multiple places and the order is consistent, you can also go for an Enum to get the drawable id in terms of a certain key of your choice. You might need to figure the key using a when condition as per position if it's really dependant on the position.

Hope that works!
