Question

我跟踪了这个家伙here并最终收到以下错误。据我所知，我不需要在运行时运行新的TableLayout()，也不需要运行新的Textview()。

以下是代码段：

public void doStats()
{       
    TableLayout table = (TableLayout) StatsActivity.this.findViewById(R.id.TableLayout01);

    String[] pattern =  splitPattern();         
    for (int i = 0; i < pattern.length; i++)
    {       

        // create a new TableRow
        TableRow row = (TableRow) LayoutInflater.from(StatsActivity.this).inflate(R.layout.attrib_row, null);

        String[] sessions = pattern[i].split("/");

        for (int y = 0; y < sessions.length; y++)
        {
            ((TextView)row.findViewById(R.id.TextView01)).setText(String.valueOf(sessions[0].toString()));
            ((TextView)row.findViewById(R.id.TextView02)).setText(String.valueOf(sessions[1].toString()));
            table.addView(row);             
        }                       
    }
    table.requestLayout(); 
}

请注意，目前我从doStats()开始onCreate。任何内部都将非常感激。
