Using setOnItemClickListener for items in listview

I have got an app that saves audio on sd card. I've created a listview which retrieves the filesnames from the sdcard. I'm trying to set a listener so when the file name is clicked I can launch another intent that plays that file. when I try to set the listener and pass in a new OnItemClickListener() eclipse is red underlining it. I understand that I have to implement the onItemclick(), this is where I think the intent ought to go.

Code:

package com.tecmark;

import java.io.File;
import java.util.ArrayList;

import android.app.Activity;
import android.os.Bundle;
import android.os.Environment;
import android.util.Log;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.AdapterView.OnItemSelectedListener;

public class SdGetList extends Activity {
    private ListView lv1;
    private String[] lv_arr;
    private ArrayList<String> arr;
        
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.listlayout);
        arr = new ArrayList<String>();

        File sdCardRoot = Environment.getExternalStorageDirectory();
        Log.i("root on sd =", ""+ sdCardRoot.getPath());

        for (File f : sdCardRoot.listFiles()) {
            if (f.isFile()){
                String name = f.getName();
                arr.add(name);
                Log.i("arr is empty?******", ""+arr.isEmpty());

            else {
                Log.i("file", " no file");
            }
            Log.i("arr******", ""+arr.size());
        }
        lv_arr = new String[arr.size()];

        for(int i=0 ; i<arr.size();i++) {
            lv_arr[i] = arr.get(i);
        }

        lv1=(ListView)findViewById(R.id.ListView01);
        // By using setAdpater method in listview we an add string array in list.
        lv1.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1 , lv_arr));
        lv1.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            }
        } );
    }
}

list.setOnItemClickListener( new OnItemClickListener() {
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
        Intent i = new Intent(ClassName.this,CourtDetailActivity.class);
        startActivity(i);
    });
}

this is the code is properly working I think you do not import blow Package

import android.widget.AdapterView.OnItemClickListener;

put this line to import section of the application

Check class imports in your java file. In Eclipse: Ctrl + Shift + O
