I create a image's array : (logos.xml)

<integer-array name="icons"><Item>@drawable/pic_01 to @drawable/pic_04<item>

Then , in my class Function : I have

public Function(String name , int icon) { this.icon = icon }



public void getIcon() { return icon; }

Final , in FunctionAdapter , I get Imageview

punlic FunctionAdapter(Context context) { icons = context.getResources().getIntArray(R.array.icons);

my question is in onBindViewHolde(@NonNull FunViewHolder holder, int position)

 holder.itemImageView.setImageResource(icons[position])

is not working , I want to know what am I miss ? Thanks Help.

I want to change my ImageView (pic1 to pic4)

my Adapter :

public class FunctionAdapter extends RecyclerView.Adapter<FunctionAdapter.FunViewHolder>

{

   private final String functions;

   private final int icons;

   Context context;



   public FunctionAdapter(Context context){

       this.context = context;

       functions  = context.getResources().getStringArray(R.array.functions);

       icons = context.getResources().getIntArray(R.array.icons);

   }



  public FunViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int i) {



  View view = LayoutInflater.from(context).inflate(R.layout.group_layout, parent,false);

   return new FunViewHolder(view);

  }



  public void onBindViewHolder(@NonNull FunViewHolder holder, int position) {



         holder.nameText.setText(functions[position]);

         holder.itemImageView.setImageResource(icons[position]);

   }



  public int getItemCount() { return functions.length; }



  public class FunViewHolder extends RecyclerView.ViewHolder{



   TextView nameText;

   ImageView itemImageView;

   public FunViewHolder(@NonNull View itemView) {

     super(itemView);

      nameText = itemView.findViewById(R.id.group_title);

      itemImageView = itemView.findViewById(R.id.group_logo);

    }

}

Update :

my mistake , logos.xml maybe the problem , but I don't know Why?

I decide to edit my icons :

private final int icons = new int{R.drawable.pic_01, R.drawable.pic_02, R.drawable.pic_03, R.drawable.pic_04} ;

then , pics will change.

you have to use String instead of String on constructor.

use

public Function(String name , int icon) { this.icon = icon }

instead of

public Function(String name , int icon) { this.icon = icon }

Use setImageDrawable() method to load local drawables instead of using setImageResource.

holder.itemImageView.setImageDrawable(context.getResources().getDrawable(icons[position]))

try this code 



 private int confirmIcon = {R.drawable.ic_action_green, 

                              R.drawable.ic_action_yellow, 

                              R.drawable.ic_action_red};







 switch ("your condition") {

            case 0:

                holder.ivConfirm.setImageResource(confirmIcon[0]);

                break;

            case 1:

                holder.ivConfirm.setImageResource(confirmIcon[1]);

                break;

            case 2:

                holder.ivConfirm.setImageResource(confirmIcon[2]);

                break;





        }
