Question

Im new in android development... why im getting this error:- "findviewbyid cannot resolve method" while using findviewbyid in viewholder method... Thanks in advance ! I want to add image from my drawable, im using recyclerview for this purpose... here's the code:-

public class ViewHolder extends RecyclerView.ViewHolder{

    TextView stateName;
    ImageView stateImage;
    public ViewHolder(@NonNull View itemView) {

        super(itemView);
        itemView.setOnClickListener(new View.OnClickListener() {

                i.putExtra("contentOfState",scontents[getAdapterPosition()]);
                v.getContext().startActivity(i);

            }
        });
        stateName=itemView.findViewById(R.id.stateName);
        stateImage=(ImageView)findViewById(R.id.imageView);
    }
}

Answer 1

findViewById() is a method of View object and not ViewHolder .

Just call it on itemView

Answer 2

你刚好错过指的itemView ，这条线替换你的stateImage线，它应该工作的罚款。

stateImage = itemView.findViewById(R.id.imageView);
