显示与 TABLELAYOUT 相加

Question

我正在使用表格布局创建日历作为屏幕显示。但是，当我需要用用户选择的新月份或年份来更新显示时，它只会将之前存储到表中的数据相加。

这是我的代码：

@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);

                            v.setText(Integer.toString(d));
                            row.addView(v, cellLp2);

                            row.setBackgroundColor(Color.rgb(55, 254, 55));

Answer 1

在 week() day() 和其他函数添加新行到表（Tablelayout）之前，考虑删除旧的表行
