Why isn't the 'getLayoutInflater()' resolving

Question

I've wanted to display TextView from content_list_drink_details.xml (topping name and topping price) to adapter of cart_layout.xml. But it appears that my getLayoutInflater() cannot be resolved.

I'm not sure if this is possible or not thus I really need help from you guys, the experts out there.

Here is my CartAdapter.java:

   public class CartAdapter extends     RecyclerView.Adapter<CartViewHolder> {

private List<Order> listData = new ArrayList<>();
private Context context;

public CartAdapter(List<Order> listData, Context context) {
    this.listData = listData;
    this.context = context;
}


@Override
public CartViewHolder onCreateViewHolder(ViewGroup parent, int     viewType) {
    LayoutInflater inflater = LayoutInflater.from(context);
    View itemView = inflater.inflate(R.layout.cart_layout,parent,false);
    return new CartViewHolder(itemView);
}

@Override
public void onBindViewHolder(CartViewHolder holder, int position) {
    TextDrawable drawable = TextDrawable.builder()
            .buildRound(""+listData.get(position).getQuantity(),     Color.parseColor("#ed008c"));
    holder.img_cart_count.setImageDrawable(drawable);

    Locale locale = new Locale("ms","MY");
    NumberFormat fmt = NumberFormat.getCurrencyInstance(locale);
    double price =     (Double.parseDouble(listData.get(position).getPrice()))*    (Integer.parseInt(listData.get(position).getQuantity()));
    holder.txt_price.setText(fmt.format(price));
holder.txt_cart_name.setText(listData.get(position).getProductName());

    //Retrieve topping name
    LayoutInflater inflater2 = this.getLayoutInflater();
    View vi = inflater2.inflate(R.layout.content_list_drink_detail,     null);
    TextView toppingName =     (TextView)vi.findViewById(R.id.toppingSelected);
    holder.txt_item_topping.setText(toppingName.getText().toString());

    //Retrieve topping price
    TextView toppingPrice =     (TextView)vi.findViewById(R.id.toppingSelectedPrice);
    holder.txt_topping_price.setText(toppingPrice.getText().toString());
}

Here is my cart_layout.xml:

Not sure what `this.getLayoutInflater();` is supposed to do since there's no such method in the class. Second, don't inflate views in onBindViewHolder, that should be done in onCreateViewHolder. — patrick.elmquist, Nov 23 '17 at 14:43

getLayoutInflater() can only be used directly inside components who has their own context like Acitivty , Application etc but Fragments don't have their own context

Solution:

Declare inflater outside viewHolder and initialize it inside constructor and use inflater instead of getLayoutInflater().

LayoutInflater inflater;
public CartAdapter(List<Order> listData, Context context) {
    this.listData = listData;
    this.context = context;
    inflater = LayoutInflater.from(context);
}


@Override
public CartViewHolder onCreateViewHolder(ViewGroup parent, int     viewType) {
    View itemView = inflater.inflate(R.layout.cart_layout,parent,false);
    return new CartViewHolder(itemView);
}

Now use

// remove it , redundant 
// LayoutInflater inflater2 = this.getLayoutInflater();
View vi = inflater.inflate(R.layout.content_list_drink_detail,null);

Update : you are inflating a new view vi who's TextView toppingName and toppingName will have no data in it , so it's empty

You might want to fetch data from list like listData.get(position).getQuantity()

// this below code is not needed at all
//LayoutInflater inflater2 = this.getLayoutInflater();
//View vi = inflater2.inflate(R.layout.content_list_drink_detail,     null);
//TextView toppingName =     (TextView)vi.findViewById(R.id.toppingSelected);
//TextView toppingPrice = (TextView)vi.findViewById(R.id.toppingSelectedPrice);

Thanks! It appears to be error free, but it does not displaying my TextView from the adapter. I believe this is another thing to handle. Will try to look at it. Thanks again – Mariam Syafiqah Saidi Nov 23 '17 at 14:44
@MariamSyafiqahSaidi i am glad that i could help, i got the issue, wait for update – Pavneet_Singh Nov 23 '17 at 14:50
@MariamSyafiqahSaidi you only need to use `holder.txt_price..` or similar code , no need to inflate extra views , just make sure you have data in list and `CartViewHolder` is properly defined – Pavneet_Singh Nov 23 '17 at 14:59
Dear sir, but my topping name and topping price data is not from List listData. They are from a textview in layout content_list_drink_detail – Mariam Syafiqah Saidi Nov 23 '17 at 15:45
@MariamSyafiqahSaidi you got two option to , either you should have a single layout for rows which contains all the required vies or you need to add your dynamic views (like `vi`) into `itemView` inside the `CartViewHolder` class , just look into [**this answer**](https://stackoverflow.com/a/40760201/4936904) , although having all views in single layout is simple and efficient – Pavneet_Singh Nov 23 '17 at 15:52
How do i add my vi into itemView? Btw thanks for your prompt replies – Mariam Syafiqah Saidi Nov 23 '17 at 16:11
@MariamSyafiqahSaidi you need to inflate the other views in `CartViewHolder` class , look carefully at the code of `VHShare` class and `imageView` along with `addView`, in the linked answer in above comment – Pavneet_Singh Nov 23 '17 at 16:15
Dear sir, GeneralFunction in my code line is showing errors. Do you have any idea on this? Do you mind if I drop you an email on this matter? – Mariam Syafiqah Saidi Nov 23 '17 at 16:51
nobody can give you any solution with this piece of information `some function with some error` , although i won't mind to take a look at it but explain the issue properly with concise details and proper error and i also insist you to post the link you gone through to solve your error – Pavneet_Singh Nov 24 '17 at 12:42

Try to replace :

LayoutInflater inflater2 = this.getLayoutInflater();

With :

 LayoutInflater inflater2 = getActivity().getLayoutInflater();
