Not able to insert image into excelsheet

问题

Hi I am trying to insert image into excel in android, using the following code but not able to do so, please help !!

// Create a path where we will place our List of objects on external // storage

               File file = new File(context.getExternalFilesDir(null), "abc.xls");
    FileOutputStream fileOS = null;
    //add picture data to this workbook.
    InputStream is = text.getResources().getAssets().open("images.jpg");
    byte[] bytes = IOUtils.toByteArray(is);
    int pictureIdx = wb.addPicture(bytes, Workbook.PICTURE_TYPE_JPEG);
    is.close();

    CreationHelper helper = wb.getCreationHelper();

    //create sheet
    Sheet sheet = wb.createSheet();

    // Create the drawing patriarch. This is the top level container for all shapes. 
    Drawing drawing = sheet.createDrawingPatriarch();

    //add a picture shape
    ClientAnchor anchor = helper.createClientAnchor();
    //set top-left corner of the picture,
    //subsequent call of Picture#resize() will operate relative to it
    anchor.setCol1(0);
    anchor.setRow1(0);
    Picture pict = drawing.createPicture(anchor, pictureIdx);

    //auto-size picture relative to its top-left corner
//  pict.resize();


//  if(wb instanceof XSSFWorkbook) file += "x";
    fileOS= new FileOutputStream(file);
    wb.write(fileOS);

Follow this:

        FileInputStream fis = new FileInputStream(imagePath);
        int b;
        byte[] bytes = IOUtils.toByteArray(fis);
        fis.close();

        // This will insert the picture from start cell to end cell of excel
        // sheet.
        HSSFClientAnchor anchor = new HSSFClientAnchor(0, 0, 0, 0,
                start.getCol(), start.getRow(), end.getCol(), end.getRow());

        anchor.setAnchorType(2);

        int index = wb.addPicture(bytes, HSSFWorkbook.PICTURE_TYPE_JPEG);

        // Create the drawing patriarch. This is the top level container for all shapes. 
        Drawing patriarch = sheet.createDrawingPatriarch();
        try {
            HSSFPicture picture = patriarch.createPicture(anchor, index);
            // picture.resize();
        } catch (Exception e) {
            String err = e.getMessage();
        }

Here start is the starting cell reference for the left-top corner of image. Similarly, end is the ending cell reference for the left-top corner of image.

CellReference start;
CellReference end;

and Note this. // Create the drawing patriarch. This is the top level container for all shapes.

Drawing drawing = sheet.createDrawingPatriarch();

Be wary of using this code. In case of Image insertion in the same sheet this code creates new Patriarch every time for new picture/image to be inserted. Make sure that for the second time image insertion this code picks the old Patriarch object for the particular sheet where insertion is to be done.
