显示正在添加TABLELAYOUT

我正在使用tablelayout创建一个日历作为我的屏幕显示。但是，当我需要用户选择新的月份或年份更新显示时，它只会将前面存储的数据添加到表格中。显示正在添加TABLELAYOUT

这里是我的代码：

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    //setContentView(R.layout.main); 

    table = new TableLayout(this); 

    FrameLayout.LayoutParams lp = new FrameLayout.LayoutParams(   
      ViewGroup.LayoutParams.FILL_PARENT,   
      ViewGroup.LayoutParams.FILL_PARENT); 
    table.setLayoutParams(lp); 
    table.setStretchAllColumns(true); 
    rowLp2 = new TableLayout.LayoutParams(   
      ViewGroup.LayoutParams.FILL_PARENT,   
      ViewGroup.LayoutParams.FILL_PARENT,   
      1.0f); 
    cellLp2 = new TableRow.LayoutParams(   
      ViewGroup.LayoutParams.FILL_PARENT,   
      ViewGroup.LayoutParams.FILL_PARENT,   
      1.0f); 
    // cellLp3 = new TableRow.LayoutParams(arg0, arg1) 
setYYMMDD(calendar.get(Calendar.YEAR),calendar.get(Calendar.MONTH),calendar.get(Calendar.DAY_OF_WEEK)); 
    leadGap = new GregorianCalendar(yy, mm, 1).get(Calendar.DAY_OF_WEEK) - 1; 
    //calling methods 
    header(); 
    weeks(); 
    //setLeadGap(2011, 2); 
    days(dom[mm]); 


    setContentView(table); 
} 

private void days(int noDays) 
{ 
    TableRow row = new TableRow(this); 
    int d=1; 
    nRow = (leadGap > 3) ? nRow+1 : nRow; 
    //textMonth.setText(Integer.toString(nRow)); 
    for (int r = 0; r <nRow ; ++r) 
    {  
     row = new TableRow(this); 
     if (r==0) 
      { int l = 0; 
       for (int f = 1; f<7; ++f) 
       { 
        if(l <leadGap) 
        { 
          TextView v = new TextView(this); 
          v.setText(""); 

          row.addView(v, cellLp2); 

          l++; 
        } 
        if (l == leadGap) 
        { 
         Button v = new Button(this); 
         v.setText(Integer.toString(d)); 
         row.addView(v, cellLp2); 
         d++; 
        } 
        row.setBackgroundColor(Color.rgb(55, 254, 55)); 

       } 
      } 
      else 
      { 

       for (int f = 0; f < 7; ++f)  
       { 

         if (d <= noDays) 
         { 
          //Button btn = new Button(this); 
          //btn.setText(Integer.toString(d));   
          //row.addView(btn, cellLp2);
