                TableRow.LayoutParams.WRAP_CONTENT));
    }

First you have one error in your code when you are setting background of table row before you have created it. You should first create new table row, and then set its background:

for (int i = 0; i < match.length; i++) {
    /** Create a TableRow dynamically **/
    tr = new TableRow(this);
    tr.setBackground(getResources().getDrawable(R.drawable.tv_bg));

You can access table row children views by index in your OnClickListener

        tr.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View v)
            {
                TableRow tr = (TableRow)v;
                TextView companyTV, valueTV, yearTV;
                String company, value, year;
                companyTV = (TextView) tr.getChildAt(0);
                valueTV = (TextView) tr.getChildAt(1);
                yearTV = (TextView) tr.getChildAt(2);
                company = companyTV.getText().toString();
                value = valueTV.getText().toString();
                year = yearTV.getText().toString();
            }
        });

If you want to track which table row is currently selected, you can create global variable for your activity

TableRow selectedTR;

and then set that inside OnClickListener

selectedTR = (TableRow)v;

When you use that selectedTR variable make sure that you check it for null value in case there is no selection made yet.
