Problem with Hello, Views: List View tutorial

Question

I've just started Android development with Eclipse, so I've been going through all the "Hello" tutorials on the Android Developers site. I have come unstuck, however, on the List View tutorial. I have tried many times to correct the problems, but I am inexperienced and whatever I do doesn't seem to work. I have copied and pasted the code directly from the site, but it still contains errors I cannot fix, so can anyone help me? Here is the code:

package com.hellolistview;

import android.app.Activity;
import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;
public class HelloListView extends ListActivity {
/** Called when the activity is first created. */


@Override
 public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);

   setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, COUNTRIES));

   ListView lv = getListView();
   lv.setTextFilterEnabled(true);

   lv.setOnItemClickListener(new OnItemClickListener() {
     public void onItemClick(AdapterView<?> parent, View view,
         int position, long id) {
       // When clicked, show a toast with the TextView text
       Toast.makeText(getApplicationContext(), ((TextView) view).getText(),
           Toast.LENGTH_SHORT).show();
     }
   });
 }
    }
    static final String[] COUNTRIES = new String[] {
    "Afghanistan", "Albania", "Algeria", "American Samoa", "Andorra",
    "Angola", "Anguilla", "Antarctica", "Antigua and Barbuda", "Argentina",

     };

The XML files have all been copied straight from the tutorial at this address so they should be correct. The errors include: "The method setOnItemClickListener(AdapterView.OnItemClickListener) in the type AdapterView is not applicable for the arguments (new OnItemClickListener(){})". Any help at all would be appreciated. Thanks.

Try to add this:

import android.widget.AdapterView.OnItemClickListener;

I think you are seeing bascially the same error. Here is the "import" part of my code.

import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
