Дисплей ДОБАВЛЯЕТСЯ с TABLELAYOUT

Question

Я создаю календарь с использованием таблицы в качестве отображения на экране. Однако, когда мне нужно обновить отображение, выбрав новый месяц или год, выбранный пользователем, он только добавляет ранее сохраненные данные в таблицу.

ЗДЕСЬ мой код:

@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));

                        d++;
                    }
                    row.setBackgroundColor(Color.rgb(55, 254, 55));

                }
            }
            else
            {

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

                        if (d <= noDays)
                        {

Answer 1

Подумайте об удалении старых таблиц перед добавлением новых строк за неделю () day () и другой функции в таблицу (Tablelayout)
