Android创建Excel表格

在Android开发中有时候我们需要将数据直接生成Excel表格并导出，

方法如下：
1.下载jxl-2.6.12.jar包：放置到Android项目的libs文件夹下，并引用依赖
2.将自己要存入表格的数据，抽象成一个实体类，例如：FaceTestEntity
3.调用jxl这个jar包的Api，生成表格，设置样式，写入数据，导出表格。

我将生成表格的代码封装成了工具类，需要的同学可以拿到直接使用，或根据自身需求修改样式参数：


public class ExcelUtil {private static WritableFont arial14font = null;private static WritableCellFormat arial14format = null;private static WritableFont arial10font = null;private static WritableCellFormat arial10format = null;private static WritableFont arial12font = null;private static WritableCellFormat arial12format = null;private final static String UTF8_ENCODING = "UTF-8";/*** 单元格的格式设置 字体大小 颜色 对齐方式、背景颜色等...*/private static void format() {try {arial14font = new WritableFont(WritableFont.ARIAL, 14, WritableFont.BOLD);arial14font.setColour(jxl.format.Colour.LIGHT_BLUE);arial14format = new WritableCellFormat(arial14font);arial14format.setAlignment(jxl.format.Alignment.CENTRE);arial14format.setBorder(jxl.format.Border.ALL, jxl.format.BorderLineStyle.THIN);arial14format.setBackground(jxl.format.Colour.VERY_LIGHT_YELLOW);arial10font = new WritableFont(WritableFont.ARIAL, 10, WritableFont.BOLD);arial10font.setColour(Colour.DARK_BLUE);arial10format = new WritableCellFormat(arial10font);arial10format.setAlignment(jxl.format.Alignment.CENTRE);arial10format.setBorder(jxl.format.Border.ALL, jxl.format.BorderLineStyle.THIN);arial10format.setBackground(Colour.GRAY_25);arial12font = new WritableFont(WritableFont.ARIAL, 10);//设置字体颜色arial12format = new WritableCellFormat(arial12font);//对齐格式arial12font.setColour(Colour.BLACK);arial12font.setPointSize(10);//设置边框arial12format.setBorder(Border.ALL, BorderLineStyle.THIN);arial12format.setAlignment(jxl.format.Alignment.CENTRE);} catch (WriteException e) {e.printStackTrace();}}public static WritableCellFormat getHeader() {WritableFont font = new WritableFont(WritableFont.TIMES, 12,WritableFont.BOLD);// 定义字体try {font.setColour(Colour.BLUE);// 蓝色字体} catch (WriteException e1) {e1.printStackTrace();}WritableCellFormat format = new WritableCellFormat(font);try {format.setAlignment(jxl.format.Alignment.CENTRE);// 左右居中format.setVerticalAlignment(jxl.format.VerticalAlignment.CENTRE);// 上下居中format.setBorder(Border.ALL, BorderLineStyle.THIN,Colour.BLACK);// 黑色边框format.setBackground(Colour.GREEN);// 黄色背景} catch (WriteException e) {e.printStackTrace();}return format;}public static <T> void setSheetHeader(Context context, String fileName, String[] colName,String sheetName, List<T> objList) {WritableWorkbook workbook = null;try {File file = new File(fileName);if (!file.exists()) {file.createNewFile();}WorkbookSettings workbookSettings = new WorkbookSettings();workbookSettings.setEncoding("UTF-8");workbookSettings.setFormulaAdjust(true);workbookSettings.setRefreshAll(true);// 创建Excel工作表OutputStream os = new FileOutputStream(file);workbook = Workbook.createWorkbook(os);//设置表格的名字WritableSheet sheet = workbook.createSheet(sheetName, 0);Label label;for (int i = 0;

}

使用方法，记得使用前申请文件读写权限

private void excelExecute() {String dirPath = Environment.getExternalStorageDirectory() + File.separator + "AndroidExcel";File file = new File(dirPath);if (!file.exists())file.mkdirs();String testExcelPath = dirPath + File.separator + "testExcel.xls";List<FaceTestEntity> list = new ArrayList<>();FaceTestEntity faceTestEntity1 = new FaceTestEntity("小狗", 1,false, 123, 234, 234,0.92);FaceTestEntity faceTestEntity2 = new FaceTestEntity("大熊", 2,false, 34, 355, 243,0.94);FaceTestEntity faceTestEntity3 = new FaceTestEntity("黑虎", 3,false, 24, 56, 356,0.90);FaceTestEntity faceTestEntity4 = new FaceTestEntity("滤后", 4,false, 25, 46, 234,0.27);FaceTestEntity faceTestEntity5 = new FaceTestEntity("祖居", 5,false, 25, 256, 234,0.46);FaceTestEntity faceTestEntity6 = new FaceTestEntity("哆啦", 6,false, 47, 47, 267,0.96);FaceTestEntity faceTestEntity7 = new FaceTestEntity("钱出", 7,false, 256, 245, 256,0.95);FaceTestEntity faceTestEntity8 = new FaceTestEntity("尽在", 8,false, 256, 256, 234,0.99);list.add(faceTestEntity1);list.add(faceTestEntity2);list.add(faceTestEntity3);list.add(faceTestEntity4);list.add(faceTestEntity5);list.add(faceTestEntity6);list.add(faceTestEntity7);list.add(faceTestEntity8);String[] colName = {"name", "trackId", "isLiveness", "RGB_Tiem","RGB_IR_Time", "compare_time", "compareSimilar"};ProgressDialog progressDialog = new ProgressDialog(this);progressDialog.setMessage("表格创建中...");progressDialog.show();ExcelUtil.initExcel(testExcelPath, "测试表1", colName);
//        ExcelUtil.setSheetHeader(this, testExcelPath, colName, "测试表1", list);ExcelUtil.writeObjListToExcel(list, testExcelPath, this);progressDialog.dismiss();}
