無法將圖像導出爲Android中的excel

我試過以下代碼以在Excel中導出圖像，但出現錯誤。複製logcat ...請幫助！無法將圖像導出爲Android中的excel

代碼：

 package com.android.testexcel; 

     import java.io.ByteArrayOutputStream; 
     import java.io.FileInputStream; 
     import java.io.FileOutputStream; 
     import java.io.IOException; 

     import org.apache.poi.hssf.usermodel.HSSFClientAnchor; 
     import org.apache.poi.hssf.usermodel.HSSFPatriarch; 
     import org.apache.poi.hssf.usermodel.HSSFSheet; 
     import org.apache.poi.hssf.usermodel.HSSFWorkbook; 

     public class MyWorkBook { 
      void writeImageToExcel(String filePath, String imageFileName) { 
       int col = 1, row = 1; 
       HSSFWorkbook wb = new HSSFWorkbook(); 
       HSSFSheet testsheet = wb.createSheet("test"); 
       System.out.println("The work book is created"); 
       try { 
        FileOutputStream fos = new FileOutputStream(filePath); 
        System.out.println("File sample.xls is created"); 
        FileInputStream fis = new FileInputStream(imageFileName); 
        ByteArrayOutputStream img_bytes = new ByteArrayOutputStream(); 
        int b; 
        while ((b = fis.read()) != -1) 
         img_bytes.write(b); 
        fis.close(); 
        HSSFClientAnchor anchor = new HSSFClientAnchor(0, 0, 0, 0, 
          (short) col, row, (short) ++col, ++row); 
        int index = wb.addPicture(img_bytes.toByteArray(), 
          HSSFWorkbook.PICTURE_TYPE_JPEG); 
        HSSFSheet sheet = wb.getSheet("test"); 
        HSSFPatriarch patriarch = sheet.createDrawingPatriarch(); 
        patriarch.createPicture(anchor, index); 
        anchor.setAnchorType(2); 
        wb.write(fos); 
        System.out.println("Writing data to the xls file"); 
        fos.close(); 
        System.out.println("File closed"); 
       } catch (IOException ioe) { 

        System.out 
          .println("Hi ! You got an exception. " + ioe.getMessage()); 
        ioe.printStackTrace(); 
       } 
      } 
     }// end of class MyWorkBook

的logcat：

由於事先與Hemant

您的錯誤的關鍵部分是這樣的：

java.lang.NoClassDefFoundError: org.apache.commons.codec.digest.DigestUtils

您需要確保在項目中包含commons編解碼器。請參閱Apache POI Components Page以獲取POI所有不同位的相關性列表。（或者，如果你使用Maven，它會爲你處理）

這個問題類似於http://stackoverflow.com/questions/9126567/method-not-found-using-digestutils-in-android 我仍然無法找到編輯源文件的最佳方式。這可以幫助我嗎？ – Hemant
