使用标记传递字符串

Question

我在自定义适配器类中创建了多个视图。我希望每个视图都与两个TextView对象相关联，每个对象都有不同的字符串作为其主文本。我在我的getView和onClick函数之间传递字符串时遇到问题。我可以用一个标签来得到它与（栅格单元）我的目标之一工作

public View getView(int position, View convertView, ViewGroup parent) { 
    View row = convertView; 
    if (row == null) { 
     LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     row = inflater.inflate(R.layout.screen_grid_date, parent, false); 
    } 

    gridcell = (TextView) row.findViewById(R.id.calendarDayButton); 
    gridcell.setOnClickListener(this); 

    gridcell.setTag(themonth + " " + theday + " " + theyear); 
    return row; 
} 


@Override 
public void onClick(View view) { 
    String month_day_year = (String) view.getTag(); 

    selectedDay.setText(month_day_year);//WORKS FIN 
} 

但我无法弄清楚如何与多个对象做到这一点。在下面，我添加了另一个名为test的TextView对象。我怎么能得到该TextView使用标签获得另一个字符串？我试着使用索引整数，那么在setTag参数字符串，但应用程序总是崩溃：

 public View getView(int position, View convertView, ViewGroup parent) { 
    View row = convertView; 
    if (row == null) { 
     LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     row = inflater.inflate(R.layout.screen_grid_date, parent, false); 
    } 

    gridcell = (TextView) row.findViewById(R.id.calendarDayButton); 
    test = (TextView) row.findViewById(R.id.test); 
    gridcell.setOnClickListener(this); 

    gridcell.setTag(1, themonth + " " + theday + " " + theyear); 
    test.setTag(2,"Test"); 
    return row; 
} 


@Override 
public void onClick(View view) { 
    String month_day_year = (String) view.getTag(1); 
    String Test = (String) view.getTag(2) 

    selectedDay.setText(Test); 
} 

我不熟悉使用一般的标签，想知道我怎么会从一个方法传递一个字符串值下一个。每次我尝试并设置一个整数作为一个标签，我得到在我的日志猫以下错误：
