Android dialog not displaying data sqlite

I am trying to display data from an SQLite database in a dialog. The data is a list of scores. All works well until I add a totals line and then it goes real haywire.

This is the source:

            DBAdaptor dbAdaptor;
        Cursor scoresCursor;
        Cursor totalsCursor;
        //ScoresDisplayerAdaptor scoresDisplayerAdaptor;  

        dbAdaptor = new DBAdaptor(this);
        dbAdaptor.open();
        scoresCursor = dbAdaptor.getScores();
        totalsCursor = dbAdaptor.getTotalScores();


        startManagingCursor(scoresCursor);
        startManagingCursor(totalsCursor);

        //scoresDisplayerAdaptor = new ScoresDisplayerAdaptor(this,scoresCursor);

        final Dialog dialog = new Dialog(this);
        dialog.setContentView(R.layout.scores);
        ListView lv = (ListView)dialog.getWindow().findViewById(R.id.lvwScores);
        ((TextView) dialog.findViewById(R.id.tvwPlayer1Name)).setText(players[0].playerName);
        ((TextView) dialog.findViewById(R.id.tvwPlayer2Name)).setText(players[1].playerName);

        switch (settings.getNumberOfPlayers())
        {
            case 2:
                lv.setAdapter(new SimpleCursorAdapter(this, R.layout.playerscoresrow, scoresCursor, 
                        new String[] {DBAdaptor.KEY_PLAYER1_SCORE,DBAdaptor.KEY_PLAYER2_SCORE}, 
                        new int[]    {R.id.tvwPlayer1Score,       R.id.tvwPlayer2Score }
                ));
                break;

            case 3: 
                ((TextView) dialog.findViewById(R.id.tvwPlayer3Name)).setText(players[2].playerName);
                lv.setAdapter(new SimpleCursorAdapter(this, R.layout.playerscoresrow, scoresCursor, 
                        new String[] {DBAdaptor.KEY_PLAYER1_SCORE,DBAdaptor.KEY_PLAYER2_SCORE,
                                      DBAdaptor.KEY_PLAYER3_SCORE}, 
                        new int[]    {R.id.tvwPlayer1Score,       R.id.tvwPlayer2Score, 
                                      R.id.tvwPlayer3Score}
                ));
                break;

            case 4:
                ((TextView) dialog.findViewById(R.id.tvwPlayer3Name)).setText(players[2].playerName);
                ((TextView) dialog.findViewById(R.id.tvwPlayer4Name)).setText(players[3].playerName);

        dialog.setTitle("Scores");
        Button aButton = (Button)dialog.findViewById(R.id.btnOK);
        aButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub

                askNewHand(); 

            } });
        dialog.show();
        dbAdaptor.close();

Where the two cursors are:

    public Cursor getScores(long rowId) throws SQLException 
{
    Cursor mCursor =
            db.query(true, DATABASE_TABLE, new String[] {
                    KEY_ROWID,
                    KEY_PLAYER1_SCORE,
                    KEY_PLAYER2_SCORE,
                    KEY_PLAYER3_SCORE,
                    KEY_PLAYER4_SCORE
                    }, 
                    KEY_ROWID + "=" + rowId, 
                    null,
                    null, 
                    null, 
                    null, 
                    null);
    if (mCursor != null) {
        mCursor.moveToFirst();
    }
    return mCursor;
}
public Cursor getTotalScores() {
    return db.rawQuery(
        "SELECT 0 as _id, SUM(" + KEY_PLAYER1_SCORE + ") as " + KEY_PLAYER1_TOTAL + ", " +
               "SUM(" + KEY_PLAYER2_SCORE + ") as " + KEY_PLAYER2_TOTAL + ", " +
               "SUM(" + KEY_PLAYER3_SCORE + ") as " + KEY_PLAYER3_TOTAL + ", " +
               "SUM(" + KEY_PLAYER4_SCORE + ") as " + KEY_PLAYER4_TOTAL + " " +
        "FROM " + DATABASE_TABLE,null);
}

The main XML looks like this:

    <?xml version="1.0" encoding="utf-8"?>

  android:layout_width="fill_parent" android:layout_height="wrap_content">

   android:layout_width="fill_parent" android:layout_height="wrap_content"
   android:layout_centerHorizontal="true" />
</RelativeLayout>

As long as the lines filling the totals are commented out then the screen displayed is ok:

However, as soon as I un-comment those lines to display the total I get this:

From what I understand, you want a fixed list (row) of players at the top of your view plus a corresponding list (row) of their total scores at the bottom. Then inbetween, you want an expanding list of scores for each hand of a game that has been played. Am I right?

EDIT: OK, ignore my suggestion of using / extending HeaderViewListAdapter as ListView supports headers/footers natively and uses HeaderViewListAdapter internally (DOH!!!).

Try the following (not sure the code is 100% correct though)...

Do what you're currently doing to set the player names in the lloPlayerNames TextViews. Then adjust your code to set the lloTotalScores TextViews to contain the values returned from your getTotalScores() query. Then use something like...

LinearLayout llHeaderView = (LinearLayout) dialog.findViewById(R.id.lloPlayerNames);
lv.addHeaderView(llHeaderView);

...

LinearLayout llFooterView = (LinearLayout) dialog.findViewById(R.id.lloTotalScores);
lv.addFooterView(llFooterView);

Then you use lv.setAdapter() to put in the results from your getScores() query. NOTE: you MUST set the header and footer before calling setAdapter()

Hope that helps.

The problem is that your root layout is a RelativeLayout. So, what's happening is your second LinearLayout is covering up the first one.

You can solve this two ways:

• Make your root layout a LinearLayout. This way, the second LinearLayout will be positioned after the first, instead of on top of it.
• Add a "Margin-top" rule of say, 100px, to the 2nd linear layout. This will push it down and expose the 1st layout...

In the end I solved this by creating a new ListView for my totals under the one for the data and populating it with a new XML that I created. I don't know if this is the optimum way to go but at least it works.
