I can create the layout I'm trying for below using XML, but I
programmatically it's not behaving the same way. I thought the
mainLayout.addview(scoreTable) would add the TableLayout to the
LinearLayout and then the objects that were already a part of the
TableLayout would be inherited:
scoreLabel.setText("Score: ");
scoreText.setText("0");
scoreRow.addView(scoreLabel);
scoreRow.addView(scoreText);
If I drop the TableLayout and TableRow and just add the TextView directly to
the LinearLayout "mainLayout.addView(scoreText); " this displays. So it
looks like it has something to do with adding the TableLayout or TableRow to
the LinearLayout.

Is your goal to define a new Layout? If it is, you should extend the
LinearLayout, for example, and do whatever you want...
If you do not know how to define your layout using XML what makes you
believe that you can do it programmatically? Maybe is this what isn't
working. You should try using XML.
If those variables are necessary for the layout, you should try the "set"
methods.
Your code is really estrange to read, and I, with my experience, your code
could be expressed with the xml layout file without any loss.

In the program I'm trying to do this in I have my own custom object that
extends View. The constructor takes some programmatically set variables.
I'm not opposed to using XML but I had up to this point been controlling my
layout programmatically and wasn't sure how to get my custom object with the
variables required by the constructor in an XML layout.

The layout definition has to be programmatically?

Can someone please explain to me why the below code does not display
anything? I am very confused.
import android.app.Activity;
import android.os.Bundle;
import android.widget.LinearLayout;
import android.widget.LinearLayout.LayoutParams;
import android.widget.TableLayout;
import android.widget.TableRow;
import android.widget.TextView;
public class LayoutTest extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LinearLayout mainLayout = new LinearLayout(this);
TableRow scoreRow = new TableRow(this);
TextView scoreLabel = new TextView(this);
TextView scoreText = new TextView(this);
TableLayout scoreTable = new TableLayout(this);
LinearLayout.LayoutParams mainLayoutParams = new
LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT);
LinearLayout.LayoutParams rowLayout = new
LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
LinearLayout.LayoutParams scoreLabelLayout = new
LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
LinearLayout.LayoutParams scoreTextLayout = new
LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
LinearLayout.LayoutParams scoreTableLayout = new
LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
mainLayout.setLayoutParams(mainLayoutParams);
scoreRow.setLayoutParams(rowLayout);
scoreLabel.setLayoutParams(scoreLabelLayout);
scoreText.setLayoutParams(scoreTextLayout);
scoreTable.setLayoutParams(scoreTableLayout);
scoreLabel.setText("Score: ");
scoreText.setText("0");
scoreRow.addView(scoreLabel);
scoreRow.addView(scoreText);
scoreTable.addView(scoreRow);
mainLayout.addView(scoreTable);
setContentView(mainLayout);
}
}
