Creating Layouts TableRows and TextViews dynamically in Android through java

We have to use "new" keyword to create objects dynamically

public class DynamicViews extends Activity {
 LinearLayout L1, L2;     // Created in xml
 LinearLayout L3;        // Created dynamically in java using "new" operator
 TableLayout TL;          // Created in xml;
 TableRow tr1, tr2, tr3;    // Created dynamically in java using "new" operator
 TextView t1, t2, t3, t4;   // Created dynamically in java using "new" operator

 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  
  <-- setContentView( int ); -->

  <-- Get L1 from xml -->
  <-- Get L2 from xml -->

  t1 = new TextView(this);
  <-- t1.setters() -->
  L2.addView(t1);

  L3 = new LinearLayout(this);
  <-- L3.setters() -->
  L3.setOrientation(LinearLayout.VERTICAL);

  <-- Get TL from xml -->
  
  tr1 = new TableRow(this);
  tr2 = new TableRow(this);

  t2 = new TextView(this);
  <-- t2.setters() -->
  tr1.addView(t2);

  
  t3 = new TextView(this);
  <-- t3.setters() -->
  L3.addView(t3);
  t4 = new TextView(this);
  <-- t4.setters() -->
  L3.addView(t4);
  tr2.addView(L3);
  TL.addView(tr1);
  TL.addView(tr2);
  TL.addView(tr3);
 }
}
