我在这里跟着这个家伙，最终得到了以下错误。据我了解，我不需要运行 new TableLayout()，也不需要 newTextview()在运行时运行。

这是代码片段：

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，目前我正在doStats()从onCreate. 任何内部将不胜感激。

移出table.addView(row)内循环。
