David,
I *think* your ListView is obscured by other views in playerlist.xml, or
just has zero width/height.
There is a bunch of views with fill_parent/fill_parent width and
height... In fact it seems that the LinearLayout which is the parent of
your ListView is pushed off the screen by the second (in the order of
occurrence) LinearLayout, which is the header layout.
I would recommend removing everything from the layout except for
ListView, sizing it fill_parent / fill_parent, verifying that this
works, and then adding other views one step at a time.

Well, I did do a check on the cursor.getCount() and it did return a
value of 1, which is what I was expecting. So, the issue must be with
displaying the data. Here is my code for populating the data and
displaying it, which I've taken from the notepad tutorial. Would
appreciate any help.
private void getAllPlayers() {
// Get all of the notes from the database and create the item list
//playerCursor = dbHelper.queryTable(PLAYERS_TABLE,
ALL_PLAYER_COLS, null, null, null, null, null);
playerCursor = dbHelper.rawQuery("SELECT * FROM players;");
int pCount = playerCursor.getCount();
startManagingCursor(playerCursor);
String[] plyData = new String[] { PLAYERS_SEX, PLAYERS_NAME,
PLAYERS_HANDICAP };
int[] plyCols = new int[] { R.id.plyIcon ,R.id.plyName,
R.id.plyHandicap };
// Now create an array adapter and set it to display using our row
ListAdapter plyAdapter =
new SimpleCursorAdapter(this, R.layout.players_rows,
playerCursor, plyData, plyCols);
setListAdapter(plyAdapter);
}
My 2 layouts for this are as follows:
*playerslist.xml*
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android";
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0"
android:gravity="left"
/>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Name"
android:textSize="20sp"
android:layout_weight="1"
android:textColor="#FFFF00"
android:gravity="center"

<TextView android:textSize="20sp"
android:id="@+id/textView1"
android:layout_height="wrap_content"
android:textColor="#FFFF00"
android:text="Handicap"
android:layout_weight="0"

android:layout_width="wrap_content"
/>
</LinearLayout>
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView android:id="@android:id/list"
android:paddingBottom="10px"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView android:id="@android:id/empty"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="@string/no_players"/>
</LinearLayout>
</LinearLayout>
*players_rows.xml*
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android";
android:layout_width="match_parent"

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0"

/>
<TextView
android:id="@+id/plyName"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="14sp"
android:textColor="#FFFFFF"
android:gravity="left">
</TextView>
<TextView
android:id="@+id/plyHandicap"
android:layout_width="match_parent"
android:layout_height="wrap_content"

</LinearLayout>
