Proper use of Android 2LineListItem

Question

I am new to Android development and trying to create a bold title list
and a smaller description for each item. As shown here (sorry, unable to post images):

This is the XML I should start with:

<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TwoLineListItem android:layout_width="fill_parent"
android:layout_height="wrap_content" android:mode="twoLine">
<TextView android:textAppearance="?android:attr/textAppearanceLarge"
android:id="@android:id/text1" android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<TextView android:layout_below="@android:id/text1"
android:textAppearance="?android:attr/textAppearanceSmall"
android:layout_alignLeft="@android:id/text1" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:id="@android:id/text2" />
</TwoLineListItem>
</LinearLayout> 

Is there a way to populate a list from an array in another XML file? If not, how would I populate a list like this from Java code? As I said, I am new to development, so I probably left. Thanks for any input!

. TwoLineListItem .

, :

public class ProfileItemAdapter extends ArrayAdapter<ProfileItem> {

private Context context;
private int layoutResourceId;   
private List<ProfileItem> objects = null;

public ProfileItemAdapter(Context context, int layoutResourceId, List<ProfileItem> objects) {
    super(context, layoutResourceId, objects);
    this.context = context;

    ProfileItem item = objects.get(position);
    TextView titletext = (TextView)v.findViewById(android.R.id.text1);
    titletext.setText(item.toString());
    TextView mainsmalltext = (TextView)v.findViewById(android.R.id.text2);
    mainsmalltext.setText(item.host);
    return v;
}

setListAdapter(new ProfileItemAdapter(getActivity(),
            android.R.layout.two_line_list_item, // or my own custom layout 
            ProfileListContent.ITEMS));

    android:layout_weight="1"
    android:orientation="vertical"  >
    <TextView
        android:id="@+id/text1"

        android:paddingRight="5dp"
        android:gravity="left|center"   >

        android:paddingRight="5dp"  >
    </TextView>
    <TextView
        android:id="@+id/text3"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textColor="#111111"

        android:paddingLeft="5dp"
        android:paddingRight="5dp"
        android:text="Project Description"  >
    </TextView>
</LinearLayout>

JAVA , . onCreate():

String[] fields = new String[]  {   db.TABLE_PRJ_NAME, db.TABLE_PRJ_TYPE, db.TABLE_PRJ_DESC };
    int[] views = new int[] {   R.id.text1, R.id.text2, R.id.text3  };

    c = db.getAllProjects();
    startManagingCursor(c);

    // Set the ListView
    SimpleCursorAdapter prjName = new SimpleCursorAdapter(
            this,
            R.layout.project_list_rows,
            //android.R.layout.simple_list_item_1,
            c, fields, views);
    setListAdapter(prjName);
