Hi Ricky,

The challenge says " The 'onListItemClick()' method of our custom Activity has been overridden, but it's empty. Add the first line of code that we normally add when overriding a method from the superclass "

Usually we call the super classes constructor after we override it. Any reason why you added a return statement? This is how it should have been

@Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        // Add code here!
      super.onListItemClick(l,v,position,id); // call overridden onListItemClick method's superclass constructor

Hope this helps.

Hi, I am having an issue with this challenge. I cannot figure out what I am doing wrong.

import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.view.View;
import android.view.ListView;
import android.content.Intent;
import android.net.Uri;

public class CustomListActivity extends ListActivity {

    protected String[] mUrls = { "http://www.teamtreehouse.com", "http://developer.android.com", "http://www.github.com" };

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_custom_list);

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mUrls);
        setListAdapter(adapter);
    }

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        // Add code here!
    super.onListItemClick(1,v,position,id);
    }
}

The error I get says:

./CustomListActivity.java:24: cannot find symbol
symbol  : method onListItemClick(int,android.view.View,int,long)
location: class ListActivity
    super.onListItemClick(1,v,position,id);
         ^
1 error

Any help would be greatly appreciated as I am pretty certain I am doing this correctly

Cheers

Bradley

You've mistakenly written 1 as in the number one instead of the letter l in your super.onListItemClick

Change it to super.onListItemClick(l,v,position,id);

thanks, I did the same thing: writing the number 1 instead of the lower case letter L.
