I'm having a little trouble with setting a custom font color for an XSSFWorkbook from Apache POI. When I do:

yellow = workbook.createCellStyle(); Font whiteFont = workbook.createFont(); whiteFont.setColor(new XSSFColor(new Color(255, 255, 255)).getIndexed()); yellow.setFillForegroundColor(new XSSFColor(yellowRGB)); yellow.setFillPattern(XSSFCellStyle.SOLID_FOREGROUND); yellow.setFont(whiteFont);

The font stays black, I'm not sure what I'm doing wrong though.

推荐答案

You can do whiteFont.setColor(new XSSFColor(new Color(255,255,255)));

However, there is a bug in Apache POI, where it is switching black and white. It looks like they put a 'fix' in XSSFColor.java (look at XSSFColor.correctRGB()) to correct for a problem in Excel. It's likely that Excel was fixed, but Apache POI wasn't updated.

Instead you can do: whiteFont.setColor(HSSFColor.WHITE.index) or whiteFont.setColor(IndexedColors.WHITE.index); (this is deprecated)

or if you do whiteFont.setColor(new XSSFColor(new Color(255,255,254))); it'll be really close to white.

其他推荐答案XSSFFont font = (XSSFFont) wb.createFont(); font.setColor(new XSSFColor( Color.decode("#7CFC00")));
