Java 我的所有Sqlitedatabase行都转换为一个简单的excel

到目前为止，我已经成功地创建了一个excel文件，并从sqlite.db中保存了一些数据

问题：如何将SQLITE数据库中的所有行保存到excel文件中？有什么建议吗 新手谢谢示例代码？一直遵循Sqlite指南 擅长我只知道如何从数据库中获取第一批数据，但我不知道如何获取所有数据？在这里使用游标是最好的方法吗

db.querySELECT*从MYTABLE中我想获取所有行和行中的所有数据，然后显示在excel文档中。c、 setCellValueitem_id

仅显示特定行中的信息该行中的所有行

  Cursor cursor = (Cursor) parent.getItemAtPosition(position);
  final int item_id = cursor.getInt(cursor.getColumnIndex(SQLiteAdapter.KEY_ID));
  String getREG = cursor.getString(cursor.getColumnIndex(SQLiteAdapter.KEY_REGNR));
  String getMATAR = cursor.getString(cursor.getColumnIndex(SQLiteAdapter.KEY_MIL));
  String getDATE = cursor.getString(cursor.getColumnIndex(SQLiteAdapter.KEY_DATUMNOW));

 Workbook wb = new HSSFWorkbook();

  Cell c = null;

   CellStyle cs = wb.createCellStyle();

   CellStyle cs_row = wb.createCellStyle();
   cs_row.setFillPattern(HSSFCellStyle.ALIGN_LEFT);

   Sheet sheet1 = null;
   sheet1 = wb.createSheet("Tankningsrapport");

   // Generate column headings
   Row row = sheet1.createRow(0);
   Row row1 = sheet1.createRow(1);

   c = row.createCell(0);
   c.setCellValue("Tankning");
   c.setCellStyle(cs);

   c = row.createCell(1);
   c.setCellValue("Datum");
   c.setCellStyle(cs);

   c = row.createCell(2);
   c.setCellValue("REGNR");
   c.setCellStyle(cs);


   c = row1.createCell(0);
   c.setCellValue(item_id);
   c.setCellStyle(cs_row);

   c = row1.createCell(1);
   c.setCellValue(getDATE);
   c.setCellStyle(cs_row);

   c = row1.createCell(2);
   c.setCellValue(getREG);
   c.setCellStyle(cs_row);

   sheet1.setColumnWidth(0, (15 * 500));
   sheet1.setColumnWidth(1, (15 * 500));
   sheet1.setColumnWidth(2, (15 * 500));

你可以试试这个它对我有用

SQLiteAdapter helper = new SQLiteAdapter(visaRapporter.this);
     helper.openToWrite();
     ArrayList<String> lis = new ArrayList<String>();

       Workbook wb = new HSSFWorkbook();


       CellStyle cs_row = wb.createCellStyle();
       cs_row.setFillPattern(HSSFCellStyle.ALIGN_LEFT);

       //New Sheet
       HSSFSheet sheet1 = null;
       sheet1 = (HSSFSheet) wb.createSheet("Tankningsrapport");

       // Generate column headings
       HSSFRow rowHead = sheet1.createRow((short) 0);

       // Head rows

在for/while列表中，我计算数据库中的每一行，并将其放入.xls文件的新行中

我将它们保存到CSV文件中，以分号分隔。默认情况下，Excel会接受这一点，这样我就不会在应用程序中放置另一个第三方库。问题不在于如何保存文件。我只是想知道如何将我所有的数据保存到excel文件中。我给了你一个替代建议。谢谢你的Vyger，但这对我现在没有帮助：也许4周前我会非常高兴。我这么做，是为了将数据从dbs共享到Microsoft world。。。我尽可能使用最少的第三方库来保持应用程序的小型化和性能。
