  <pre><code>button_generate.setOnClickListener(new View.OnClickListener() {
                      public void onClick(View v) {
                                 //*-----------clearing the variables--------*
                          final TableLayout rel=(TableLayout)findViewById(R.id.tab1);
  
  
  
                          int k=0,i=0,j=0;
  
                                    count=3;
                                      System.out.println("count is"+count);
  
                                      while(j&lt;count)      
                                      {
