Bizzare android table row issue

I am programmatically trying to add views to my table layout in Android. But I am not able to add more than 1 view to my row. It only renders the first view. The second column is empty. My code is as below.

    LayoutParams lp = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    TableRow tr1 = new TableRow(this);
    TableRow tr2 = new TableRow(this);
    TextView productNumber = new TextView(this);
    productNumber.setText("PRODUCT NUMBER: " + b[0].getProduct_id());
    productNumber.setTextSize(18);
    productNumber.setTextColor(Color.RED);
    productNumber.setPadding(20, 5, 20, 5);
    tr1.addView(productNumber);
    TextView productDesc = new TextView(this);
    productDesc.setText("PRODUCT DESCRIPTION: " + b[0].getItem_description());
    productDesc.setTextSize(18);
    productDesc.setTextColor(Color.RED);
    productDesc.setPadding(20, 5, 20, 5);
    tr2.addView(productDesc);
    productNumber.setLayoutParams(lp);
    productDesc.setLayoutParams(lp);
    tl.setStretchAllColumns(true);
    tl.addView(tr1, new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT, TableLayout.LayoutParams.WRAP_CONTENT));
    tl.addView(tr2, new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT, TableLayout.LayoutParams.WRAP_CONTENT));



    for (ProductBean p: b) {
        TableRow lineSeparator = new TableRow(this.getApplicationContext());
        View line = new View(this.getApplicationContext());
        line.setMinimumHeight(1);
        line.setBackgroundColor(Color.WHITE);
        line.setPadding(0, 5, 0, 5);
        lineSeparator.addView(line);
        tl.addView(lineSeparator);
        Set<String> headers = p.getAttr().keySet();

    //Till here it works fine. The following code seems to not add more than 1 view

        for (String s: headers) {
            Log.i("S", "S: " + p.getAttr().get(s));
            TableRow tableRow = new TableRow(getApplicationContext());
            TextView textView = new TextView(getApplicationContext());
            textView.setText(s);
            textView.setPadding(20, 5, 20, 5);
            textView.setTextSize(15);
            tableRow.addView(textView);
            textView = new TextView(getApplicationContext());
            textView.setText(p.getAttr().get(s));
            textView.setPadding(20, 5, 20, 5);
            textView.setTextSize(15);
            tableRow.addView(textView); //This view is not rendered.
            tl.addView(tableRow);
        }
    }

However, I tried the following in a separate activity and layout and it worked successfully. Hello is one column and World another.

    for (int i=0; i<5; i++) {
        TableRow tableRow = new TableRow(getApplicationContext());
        TextView textView = new TextView(getApplicationContext());
        textView.setText("Hello");
        tableRow.addView(textView);
        textView = new TextView(getApplicationContext());
        textView.setText("World"); 
        tableRow.addView(textView);
        tableLayout.addView(tableRow);
    }

Why is my code not rendering the second view then? I am able to log the contents of both the textviews but it just doesn't render the second view in the row. Please help. I am utterly lost, been beating my head over it for 12 hours now!!
