Adding Secondary Data with a SimpleAdapter Code Challenge part 1

import android.os.Bundle;
import android.widget.SimpleAdapter;

public class WebsiteListActivity extends ListActivity {

    public static final String KEY_NAME = "name";
    public static final String KEY_URL = "url";

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

        String[] keys = { KEY_NAME, KEY_URL };
        int[] ids = { android.R.id.text1, android.R.id.text2 };

        HashMap<String, String> name = new HashMap<String, String>();
        name.put(KEY_NAME, value);
          name.put(KEY_URL, value);

        HashMap<String, String> url = new HashMap<String, String>();
        url.put(KEY_NAME, value);
        url.put(KEY_URL, value);

    }

Try adding some String values to where you have written value.

Something like this will pass the code challenge:

HashMap<String, String> name = new HashMap<String, String>();
name.put(KEY_NAME, "One");
name.put(KEY_URL, "Two");

HashMap<String, String> url = new HashMap<String, String>();
url.put(KEY_NAME, "Three");
url.put(KEY_URL, "Four");

Changing the "value" to KEY_URL as the second parameter of the put methods will pass the challenge as well.

HashMap<String, String> name = new HashMap<String, String>();
        name.put(KEY_NAME, KEY_URL);
        name.put(KEY_URL, KEY_URL);

        HashMap<String, String> url = new HashMap<String, String>();
        url.put(KEY_NAME, KEY_URL);
        url.put(KEY_URL, KEY_URL);
