我在自定義適配器類中創建了多個視圖。我希望每個視圖都與兩個TextView對象相關聯,每個對象都有不同的字符串作爲其主文本。我在我的getView和onClick函數之間傳遞字符串時遇到問題。我可以用一個標籤來得到它與(柵格單元)我的目標之一工作使用標記傳遞字符串

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 
} 

但我無法弄清楚如何與多個對象做到這一點。在下面,我添加了另一個名爲test的TextView對象。我怎麼能得到該TextView使用標籤獲得另一個字符串?我試着使用索引整數,那麼在setTag參數字符串,但應用程序總是崩潰:

 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標籤,想知道我怎麼會從一個方法傳遞一個字符串值下一個。每次我嘗試並設置一個整數作爲一個標籤,我得到在我的日誌貓以下錯誤:

just use,'gridcell.setTag(1,themonth +「」+ theday +「」+ theyear); gridcell.setTag(2,「Test」);'只有一個'TextView gridcell',這會適用於您的onClick。 – user370305

它不會允許我用戶1或2等。我的日誌貓不斷給我這個錯誤:密鑰必須是特定於應用程序的資源ID。 –

調用onClick是否有任何限制點擊一個TextView? – user370305
