由數據庫創建的列表視圖中的getText（）

我有一個由數據庫填充的列表，我正在運行OnItemClick（）方法。我會打電話來從被點擊的項目中獲取文本？由數據庫創建的列表視圖中的getText（）

public void DisplayRecord(Cursor c) { 
    Cursor c1 = DBAdapter.getAllRecords(); 
    startManagingCursor(c1); 

    String[] from = new String[] { DBAdapter.KEY_ITEM }; 
    int[] to = new int[] { R.id.text1 }; 

    SimpleCursorAdapter notes = new SimpleCursorAdapter(this, R.layout.row, 
      c1, from, to); 
    setListAdapter(notes); 
} 

@Override 
public void onListItemClick(ListView l, View view, int position, long id) { 
    switch (position) { 
    case 0: 
     //method to getText()? 

     break; 
    } 
}

logcat的：

Cursor c = this.getContentResolver().query(DBAdapter.getAllRecords(),null,null,null,null); 

@Override 
public void onListItemClick(ListView l, View view, int position, long id) {     
     c.moveToPosition(position); 
     String s = c.getString(c.getColumnIndex(DBAdapter.KEY_ITEM)); 

}

這給了我一堆的錯誤，並說數據庫沒有打開，查詢有錯誤， –

@CoreyWilliams：你可以發佈你的logcat錯誤嗎？ – Deepzz

更新的原貼 –

您可以使用您的陣列，像;

@Override 
public void onListItemClick(ListView l, View view, int position, long id) { 
    String fromtext = from[position]; 
}

我不認爲這是正確的。 'from'數組包含一個鍵名。 –

這從數據庫到A，B（ArrayList的）碼爲附加日期,,這裏被浮動的ArrayList ,,這裏b爲整數數組列表

 public void data() 
     { 
    mySQLiteAdapter = new SQLiteAdapter(getActivity()); 
    mySQLiteAdapter.openToRead(); 
    Cursor c = mySQLiteAdapter.queueAll("TABLE NAME",COLUMN NAME,CONDITION); 

    //************************************************add date from database 
     if(c.moveToFirst()) 
      do { 

       a.add(c.getString(0));// here a is Float Arraylist, 0 represent first column 
      b.add(c.getInt(1));// here b is Integer Array list, 1 represent second column 

      } 
      while (c.moveToNext()); 
     }

和「可變.get（position）'從Array列表中獲取infrormation

public void onListItemClick(ListView l, View view, int position, long id) { 
    switch (position) { 
     case 0: 
    //method to getText()? 
     xxx.SetText(a.get(position)); 
    break; 
}
