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)


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) {


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

  public class FunViewHolder extends RecyclerView.ViewHolder{

   TextView nameText;
   ImageView itemImageView;
   public FunViewHolder(@NonNull View itemView) {
      nameText = itemView.findViewById(;
      itemImageView = itemView.findViewById(;

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.


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

instead of

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