    <p>I have already created a dynamic list view that passes text to a SimpleAdapter, however I would like to pass information to make an image appear from the drawable folder. Here is the XML layout for each row:</p> <p> </p> <pre><code>&lt;ImageView android:id="@+id/sport_icon" android:layout_width="wrap_content" android:layout_height="wrap_content" /&gt; &lt;TextView android:id="@+id/item_title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textAppearance="?android:attr/textAppearanceMedium" android:padding="2dp" android:textSize="20dp" /&gt; &lt;LinearLayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="right" &gt; &lt;TextView android:id="@+id/item_subtitle" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="2dp" android:textSize="13dp" /&gt; &lt;/LinearLayout&gt; &lt;/LinearLayout&gt; </code></pre> <p></p> <p>and the bit of code creating the list:</p> <pre><code>//fill in the list items from the XML document for (int i = 0; i &lt; nodes.getLength(); i++) { HashMap&lt;String, String&gt; map = new HashMap&lt;String, String&gt;(); Element e = (Element)nodes.item(i); map.put("id", XMLfunctions.getValue(e, "fixture_id")); map.put("sport", XMLfunctions.getValue(e, "sport")); map.put("teams", XMLfunctions.getValue(e, "team_2") + " v " + XMLfunctions.getValue(e, "team_2")); mylist.add(map); } //Make a new listadapter ListAdapter adapter = new SimpleAdapter(this, mylist, R.layout.fixture, new String[] { "sport", "teams" }, new int[] { R.id.item_title, R.id.item_subtitle }); setListAdapter(adapter); </code></pre> <p>Now at the moment when I pass the string sport it just displays the text such as 'football' in the item_title text view. But as I know what the sport is I would like to be able to display an icon in the sport_icon imageview. An example of the sport icon location would be @drawable/icon_football.</p> <p>Many thanks.</p> <hr> <p>The answer here was creating a BaseAdapter with the ListView as suggested by Frank below. If anyone else is looking to do the same thing but has no idea where to start I highly recommend watching <a href="http://www.youtube.com/watch?v=pVs4qKmenQM" rel="nofollow">http://www.youtube.com/watch?v=pVs4qKmenQM</a>. This video is well put together and explains everything you need to know.</p> <p>:)</p>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
