Accepting user data into a table

I'm designing an app which will accept user input into a TableLayout . The table has 4 headings . I'm unsure of how to get the data into the table . I have a successfully added a test piece of code but I can only add it once. I've attached the code below.

public void addNew(){
    TableLayout tL = (TableLayout)findViewById(R.id.table);
    TableRow tR = new TableRow(getApplicationContext());
    TextView tV = new TextView(getApplicationContext());

    tV.setTextColor(0xff000000);
    tV.setText("TEST");


    TextView tV2 = new TextView(getApplicationContext());
    tV2.setTextColor(0xff000000);
    tV2.setText("TEST");

    TextView tV3 = new TextView(getApplicationContext());
    tV3.setTextColor(0xff000000);
    tV3.setText("TEST");

    TextView tV4 = new TextView(getApplicationContext());
    tV4.setTextColor(0xff000000);
    tV4.setText("TEST");

    tR.addView(tV);
    tR.addView(tV2);
    tR.addView(tV3);
    tR.addView(tV4);


    tL.addView(tR);

}
