Android：預加載數據庫到表佈局視圖

我試圖弄清楚如何從我的資產文件夾中的預填充數據庫中提取信息以顯示在tablelayout視圖中。如果你知道任何明確的教程，或者如果你知道如何做到這一點，你可以幫助我。我的意思Android：預加載數據庫到表佈局視圖

例子：

數據庫例如：

  Mountains  Valleys Rivers  Oceans

Vermount是否是否

肯塔基否是是

南達科他州是否否否

（在應用程序中，如果我要顯示一個特定IC行則tablelayout應該出現這樣的）

TableLayout查看

  South Dakota   <--(I know how to put the header) 

     Mountains  yes 
     Valleys   no 
     Rivers   no 
     Oceans   no

你感到困惑複製這樣做佈局，還是數據庫操作？ – Codeman

什麼不工作？ –

在兩種方式中，我知道我需要使用遊標從數據庫中提取信息，但我不知道如何將它與tablelayout結合起來。 – Nate

我必須做同樣的事情，但並不需要一個光標。這是我最終爲我的項目做的。它會顯示一個對話框，顯示無限進度微調器。

private class AsyncPop extends AsyncTask<Dialog, Integer, ScrollView> 
{ 
    @Override 
    protected void onPostExecute(ScrollView result) 
    { 
     setContentView(result); 
     super.onPostExecute(result); 
    } 

    @Override 
    protected ScrollView doInBackground(Dialog... params) 
    { 
     Dialog d = params[0]; 

     Connection con = StaticDBHelper.getCon(TabActivityDetail.this.getParent()); 
     Statement st = null; 

     List<Timestamp> date = new ArrayList<Timestamp>(); 
     List<String> text = new ArrayList<String>(); 
     try 
     { 
      st = con.createStatement(); 
      String sql = "select activityDateTime, detailText from xfu_ActivityDetail order by activityDateTime desc"; 
      st.execute(sql); 
      ResultSet rs = st.getResultSet(); 

      while(rs.next()) 
      { 
       date.add(rs.getTimestamp("activityDateTime")); 
       text.add(rs.getString("detailText")); 
      } 
      rs.close(); 

     }

爲什麼你想將其添加到TableLayout？

Just fetch data from SQLite database and using custom adapter use ListView.

所以使用多列的ListView設置在列類型的所有值，

看Multicolumn ListView in Android

我相信你需要將數據庫從你的資產文件夾複製出來到別的地方之前，你可以用它
