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;

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 {

  1. getSystemService is a method of Context class, so try to get a Context object first:

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