Problems with dynamically adding TableRow in TableLayout

Question

My code:

public class Test extends Activity {

private TableLayout tableLayout = null;
private Button add = null;

@Override
public void onCreate(Bundle icicle) {

    super.onCreate(icicle);

    setContentView(R.layout.main);

    tableLayout = (TableLayout)findViewById(R.id.tableLayout);

    add = (Button)findViewById(R.id.agregar);
    add.setOnClickListener(new OnClickListener(){
        @Override
        public void onClick(View v) {
            TableRow fila = new TableRow(Test.this);
            Button eliminar = new Button(Test.this);
            eliminar.setText("delete");
            eliminar.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
            fila.addView(eliminar,new TableLayout.LayoutParams(
                      LayoutParams.WRAP_CONTENT,
                      LayoutParams.WRAP_CONTENT));
            tableLayout.addView(fila,new TableLayout.LayoutParams(
                      LayoutParams.MATCH_PARENT,
                      LayoutParams.WRAP_CONTENT));
        }
    });
}

I want it to add a new row every time I click on the add Button. My xml is the following one:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<RelativeLayout
    android:id="@+id/relativelayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <TableLayout
        android:id="@+id/tableLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <TableRow
            android:id="@+id/tableRow1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" >

            <TextView
                android:id="@+id/textView1"
                android:text="Column 1"
                android:textAppearance="?android:attr/textAppearanceLarge" />

            <Button
                android:id="@+id/button1"
                android:text="Delete" />
        </TableRow>
    </TableLayout>

    <Button
        android:id="@+id/agregar"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/tableLayout"
        android:text="Add" />
</RelativeLayout>

Every time I click on the Button, it does nothing. Can somebody help me with this?

The OP wrote:

I found out that they can not be LayoutParams. If they are part of a TableRow, they have to be TableRow.LayoutParams and if they are inside the TableLayout, they have to be TableLayout.LayoutParams. Like the following one:
eliminar.setLayoutParams(new TableRow.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
            fila.addView(eliminar,new TableRow.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
            tableLayout.addView(fila,new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
