Error in arrayadapter

Please help me friends. What is wrong in this program. I cant use LayoutInflater here. how To solve this problem.

public class MyListAdapter extends ArrayAdapter<MyData> implements
        OnClickListener {

    private ArrayList<MyData> items;
    Context context;

    public MyListAdapter(Context context, int textViewResourceId,
            ArrayList<MyData> items) {
        super(context, textViewResourceId, items);
        this.items = items;
        this.context = context;
    }

    @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.row, null);
        }

        MyData myData = items.get(position);
        if (myData != null) {
            TextView textViewTwo = (TextView) v
                    .findViewById(R.id.text_view_two);
            if (textViewTwo != null) {
                textViewTwo.setText(myData.getText());
                // put the id to identify the item clicked
                textViewTwo.setTag(myData.getId());
                textViewTwo.setOnClickListener(this);
            }
        }
        return v;
    }

    public void onClick(View v) {
        // TODO Auto-generated method stub
        Log.d("Sample", "Clicked on tag: " + v.getTag());
        Toast.makeText(context, "", Toast.LENGTH_SHORT).show();

    }

}

Error is : The method getSystemService(String) is undefined for the type MyListAdapter.

Thanks in advance.

Use Activity's context to get the system services

This is the right way to call the inflator.

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

Try context.getStystemService() like this

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

use

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

instead of

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

because for getSystemService is method of Context class instead of ArrayAdapter . u will need to use context instance to access getSystemService method
