Android getSystemService inside custom ArrayAdapter

I was trying to write a custom ArrayAdapter referencing here My code is

package com.example.AndTest;



import java.util.ArrayList;



import android.content.Context;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.ArrayAdapter;

import android.widget.TextView;



public class CategoryAdapter extends ArrayAdapter<Category> {

    private ArrayList<Category> items;



    public CategoryAdapter(Context context, int textViewResourceId,

            ArrayList<Category> items) {

        super(context, textViewResourceId, items);

        this.items = items;

    }



    @Override

    public View getView(int position, View convertView, ViewGroup parent) {

        View v = convertView;

        if (v == null) {

            LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            v = vi.inflate(R.layout.list, null);

        }

        Category c = items.get(position);

        if (c != null) {

            TextView itemId = (TextView) v.findViewById(R.id.itemid);

            TextView itemLabel = (TextView) v.findViewById(R.id.itemlabel);

            if (itemId != null) {

                itemId.setText("Name: " + c.getId());

            }

            if (itemLabel != null) {

                itemLabel.setText("Status: " + c.getTitle());

            }

        }

        return v;

    }

}

But I'm getting error message on the line LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

The method getSystemService(String) is undefined for the type CategoryAdapter

Am i missing something..

public class Category implements Parcelable {

....

}
