Creating RecyclerView and adjusting its margins

 

public class RecylerView_ScannedDocumentAdapter extends RecyclerView.Adapter<RecylerView_ScannedDocumentAdapter.ViewHolder> {
    private Context context;
    private List<Uri>imageUris;

    public RecylerView_ScannedDocumentAdapter(Context context,List<Uri>imageUris) {
        this.context=context;
        this.imageUris=imageUris;
    }

    @NonNull

    // for adding the layout inflater
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view= LayoutInflater.from(context).inflate(R.layout.rv_item_scanned_images,parent,false);
        return new ViewHolder(view);
    }

    //adding the data to the files
    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        Uri imageUri=imageUris.get(position);
        holder.iv_scannedImages.setImageURI(imageUri);

    }

    //for running the recyclerview for specific length
    @Override
    public int getItemCount() {
        return imageUris.size();
    }





    public static class ViewHolder extends RecyclerView.ViewHolder{
        ImageView iv_scannedImages;

        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            iv_scannedImages=itemView.findViewById(R.id.iv_scannedImages);
        }
    }
}

rv_showScannedDocument = findViewById(R.id.rv_showScannedDocument);
rv_showScannedDocument.setLayoutManager(new LinearLayoutManager(this));
recylerView_scannedDocumentAdapter = new RecylerView_ScannedDocumentAdapter(this, imageUris);
rv_showScannedDocument.setAdapter(recylerView_scannedDocumentAdapter);


add margins to the items of recycler view 

if (position == fileName.size() - 1) {
    // Set bottom margin for the last item
    ViewGroup.MarginLayoutParams layoutParams = (ViewGroup.MarginLayoutParams) holder.itemView.getLayoutParams();
    layoutParams.bottomMargin = 250; // Set the margin you want
    holder.itemView.setLayoutParams(layoutParams);
} else {
    // Remove margin for other items (optional)
    ViewGroup.MarginLayoutParams layoutParams = (ViewGroup.MarginLayoutParams) holder.itemView.getLayoutParams();
    layoutParams.bottomMargin = 0; // Reset margin for non-last items
    holder.itemView.setLayoutParams(layoutParams);
}
