Agregar, guardar y eliminar tablerow

Quiero crear un table con un button that every time it is clicked adds a tablerow con tres TextView. For the moment I could only add to the tablerow sin TextView, however, has the problem that when I close the application the lines created are not saved, who can help me?

Este es mi codigo:

public class MainActivity extends Activity {

    protected void onCreate(Bundle savedInstanceState) {
        Button btnAddItem = (Button) findViewById(;
        btnAddItem.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {

                TableLayout table = (TableLayout) findViewById(;

                TableRow row = new TableRow(MainActivity.this);

                TextView t = new TextView(MainActivity.this);

                t.setText("Add table row");

You can't add permanently views to a Layout ("permanently" means that survive to the application being closed).

If you are referring to the application being put in background (i.e. when the user presses the home button), or when the user turns the device, or when you start another activity and you go back to this one android gives you the possibility to "save" the state of your activity with two callbacks: namely onSaveInstanceState y onRestoreInstanceState

public void onSaveInstanceState(Bundle savedInstanceState) {
    savedInstanceState.putInt("numRows", rowsNum);
    for (int i=1;i<rowsNum+1;i++) {
         savedInstanceState.putString("row"+i+"1", "Text of the first row first cell");
         savedInstanceState.putString("row"+i+"2", "Text of the first row second cell");
         savedInstanceState.putString("row"+i+"3", "Text of the first row third cell");

public void onRestoreInstanceState(Bundle savedInstanceState) {
    int numRows = savedInstanceState.getInt("numRows");
    for (int i=1;i<rowsNum+1;i++) {
         String cell1 = savedInstanceState.getString("row"+i+"1");
         String cell2 = savedInstanceState.getString("row"+i+"2");
         String cell3 = savedInstanceState.getString("row"+i+"3");
         //re-create the table here from the strings

Espero que esto ayude
