如何從從資產文件中讀取的xml數據動態創建可單擊的文本視圖？

Question

我已經完成了我的功課。

我有一個應用程序讀取資產的XML文件，其中包含第一個字段以大寫字母開頭的條目。

我讀了XML，我想DYNAMICALLY創建CLICKABLE textviews，以便我可以顯示按第一個字母分組的其餘數據。

我在這裏包括我的應用程序的所有相關文件。

現在所有的應用程序都會顯示Log.v，我會讀取所有需要的數據。

我故意讓layout.xml幾乎爲空。我想動態創建textviews。

任何一個爲我寫的代碼的其餘部分！

我希望你爲我做什麼或者告訴我是如何 - 當我閱讀XML文件時 - 爲每個新字母字母動態創建一個可單擊的textView，我在字段中找到並顯示它的佈局...

您需要創建循環，具體取決於包含解析數據的ArrayList的大小。 而在這裏創建動態textviews是代碼：

for (int i = 0; i < Tel.size(); i++) { 

       final TextView phone = new TextView(context); 
       phone.setTextAppearance(context, 
         android.R.style.TextAppearance_Medium); 
       phone.setText(Tel.get(i)); 
       phone.setTypeface(Typeface.DEFAULT); 
       phone.setTextColor(Color.BLUE); 
       phone.setPaintFlags(phone.getPaintFlags() 
         | Paint.UNDERLINE_TEXT_FLAG); 

       phone.setOnClickListener(new OnClickListener() { 

        @Override 
        public void onClick(View v) { 

         Call(phone.getText().toString()); 

        } 
       }); 

       InfoContainer.addView(phone); 

      } 

這裏電話是包含所有電話號碼我的數組列表。而InfoContainer是我的父代linearlayout，我在其中添加了這些動態創建的文本視圖。
