Hussain Mansuri :
I am new to android and java. I am not able to call ViewHolder.setCategoryName(name); in the onBindViewHolder function. I know there are probably similar questions but nothing has worked for me yet. The compiler gives error "non-static functions cannot be called from a static context", I haven't used static keyword anywhere in my code.
public class CategoryAdapter extends RecyclerView.Adapter<CategoryAdapter.ViewHolder> {
private List<CategoryModel> categoryModelList;
public CategoryAdapter(List<CategoryModel> categoryModelList) {
this.categoryModelList = categoryModelList;
}
@NonNull
@Override
public CategoryAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int position) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.category_item,viewGroup,false);
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(@NonNull CategoryAdapter.ViewHolder holder, int position) {
String icon = categoryModelList.get(position).getCategoryIconLink();
String name = categoryModelList.get(position).getCategoryName();
ViewHolder.setCategoryName(name);
}
@Override
public int getItemCount() {
return categoryModelList.size();
}
public class ViewHolder extends RecyclerView.ViewHolder{
private ImageView categoryIcon;
private TextView categoryName;
public ViewHolder(@NonNull View itemView) {
super(itemView);
categoryIcon = itemView.findViewById(R.id.category_icon);
categoryName = itemView.findViewById(R.id.category_name);
}
private void setCategoryIcon(){
}
private void setCategoryName(String name){
categoryName.setText(name);
}
}
}

try this:
public class CategoryAdapter extends RecyclerView.Adapter<CategoryAdapter.ViewHolder> {
private List<CategoryModel> categoryModelList;
public CategoryAdapter(List<CategoryModel> categoryModelList) {
this.categoryModelList = categoryModelList;
}
@NonNull
@Override
public CategoryAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int position) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.category_item,viewGroup,false);
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(@NonNull CategoryAdapter.ViewHolder holder, int position) {
holder.bind(categoryModelList.get(position))
}
@Override
public int getItemCount() {
return categoryModelList.size();
}
public class ViewHolder extends RecyclerView.ViewHolder{
private ImageView categoryIcon;
private TextView categoryName;
public ViewHolder(@NonNull View itemView) {
super(itemView);
categoryIcon = itemView.findViewById(R.id.category_icon);
categoryName = itemView.findViewById(R.id.category_name);
}
public void bind(CategoryModel categoryModel){
categoryName.setText(categoryModel.getCategoryName());
}
}
}
