Here is the solution. Thank you Mark Murphy for you guidance and for the excerpt from your book (found on the link you provided above).
The purpose of this exercise is to use ListView for app navigation instead of a menu. In /res/layout create menu_list_item.xml: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/ android" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:padding="6dip"> <ImageView android:id="@+id/icon" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_alignParentTop="true" android:layout_alignParentBottom="true" android:layout_marginRight="6dip" /> <TextView android:id="@+id/summary" android:layout_width="fill_parent" android:layout_height="26dip" android:layout_toRightOf="@id/icon" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" android:singleLine="true" android:ellipsize="marquee" android:textAppearance="@style/TextAppearance.Summary" /> <TextView android:id="@+id/title" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_toRightOf="@id/icon" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:layout_above="@id/summary" android:layout_alignWithParentIfMissing="true" android:gravity="center_vertical" android:textAppearance="@style/TextAppearance.Title" /> </RelativeLayout> In /res/xml create file main_screen_actions.xml that looks like this: <?xml version="1.0" encoding="utf-8"?> <resources xmlns:android="http://schemas.android.com/apk/res/android";> <item icon="@drawable/icon1" title="Guest" summary="Perform guest operations." /> <item icon="@drawable/icon2" title="Login" summary="Login to your account." /> <item icon="@drawable/icon3" title="Register" summary="Create new account." /> </resources> Create class: public class ListMenuDescriptor { public int iconId; public String title; public String summary; /** * Constructor * * @param iconId Id of the icon resource. * @param title Menu item title. * @param summary Short menu description. */ public ListMenuDescriptor(int iconId, String title, String summary) { this.iconId = iconId; this.title = title; this.summary = summary; } } Create class: public class ListMenuArrayAdapter extends ArrayAdapter<ListMenuDescriptor> { private LayoutInflater _inflater; /** * Item tag for list menu items describing xml resource file. */ public static final String ITEM_TAG = "item"; /** * Icon resource attribute. */ public static final String ICON_ATTR = "icon"; /** * Title attribute. */ public static final String TITLE_ATTR = "title"; /** * Summary attribute. */ public static final String SUMMARY_ATTR = "summary"; /** * Constructor * * @param context * The current context. * @param items * List menu items. */ public ListMenuArrayAdapter(Context context, ArrayList<ListMenuDescriptor> items) { super(context, R.layout.menu_list_item, items); _inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); } /** * Creates ListMenuArrayAdapter from xml resource. * * @param context * The context. * @param listMenuItemsResId * Id of the resource describing list menu items. * @return ListMenuArrayAdapter */ public static ListMenuArrayAdapter createFromResource(Context context, int listMenuItemsResId) { ArrayList<ListMenuDescriptor> items = new ArrayList<ListMenuDescriptor>(); // inflate and create the list XmlResourceParser parser = context.getResources().getXml( listMenuItemsResId); try { while (parser.getEventType() != XmlResourceParser.END_DOCUMENT) { if (parser.getEventType() == XmlResourceParser.START_TAG) { String tag = parser.getName(); if (tag.equals(ITEM_TAG)) { items.add(new ListMenuDescriptor(parser.getAttributeResourceValue(null, ICON_ATTR, 0), parser.getAttributeValue(null, TITLE_ATTR), parser.getAttributeValue(null, SUMMARY_ATTR))); } } parser.next(); } } catch (XmlPullParserException xpe) { Log.e(ListMenuArrayAdapter.class.getName(), Log.getStackTraceString(xpe)); throw new RuntimeException(xpe); } catch (IOException ioe) { Log.e(ListMenuArrayAdapter.class.getName(), Log.getStackTraceString(ioe)); throw new RuntimeException(ioe); } finally { parser.close(); } return new ListMenuArrayAdapter(context, items); } @Override public View getView(int position, View convertView, ViewGroup parent) { View row = convertView; if (row == null) { row = _inflater.inflate(R.layout.menu_list_item, parent, false); } ListMenuDescriptor descriptor = this.getItem(position); TextView txt = (TextView) row.findViewById(R.id.title); txt.setText(descriptor.title); txt = (TextView) row.findViewById(R.id.summary); txt.setText(descriptor.summary); ImageView ico = (ImageView) row.findViewById(R.id.icon); ico.setImageResource(descriptor.iconId); return row; } } And finally in your ListActivity wire it up like so: this.setListAdapter(ListMenuArrayAdapter.createFromResource(this, R.xml.main_screen_actions)); I hope somebody will find that useful.
