Android 将数据保存到已有的固定模板的Excel表中
继上篇文章讲诉的是如何将数据保存到一个新建的Excel表格中，这篇文章咋一起来看下如何将数据保存到一个固定模板的Excel表格中，因为在实际的开发过程中，很多情况下都是公司给提供一个固定模板的Excel表格，然后要求我们将数据填充到固定的单元格中，下面就一起来看下如何实现
先上效果图：
1、一般情况下我们会用第三方的jar包来帮助实现，比如 jxl.jar ， poi.jar
点击下载
2、需要注意的是开发的时候（因为项目中用的是 jxl.jar包，所以接下来是以该jar包为主的）
1）、如果你用的是jxl.jar包的话模板的Excel表格必须是97-03版的Excel，否则的话 jxl.jar 是没法进行解析的
2）、如果你用的是poi.jar包的话模板的Excel表格是没有要求
3）、将模板Excel放在raw 或者 assets下
3、同样开发的时候需要注意加上读写权限，尤其在Android 6.0 的时候需要动态去申请读写的权限
if (ContextCompat.checkSelfPermission(this,Manifest.permission.WRITE_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE},
MY_PERMISSIONS_REQUEST);
} else {
printer();
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
if (requestCode == MY_PERMISSIONS_REQUEST) {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
printer();
} else {
// Permission Denied
Toast.makeText(MainActivity.this, "Permission Denied", Toast.LENGTH_SHORT).show();
}
return;
}
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
} 4、指定Excel文件存放的文件夹，并为文件取名
public void saveFile(String fileName, Context context, int rawid) throws IOException {
// 首先判断该目录下的文件夹是否存在
File dir = new File(Environment.getExternalStorageDirectory() + "/inspection/");
if (!dir.exists()) {
// 文件夹不存在 ， 则创建文件夹
dir.mkdirs();
}
// 判断目标文件是否存在
File file1 = new File(dir, fileName);
if (!file1.exists()) {
file1.createNewFile(); // 创建文件
}
// 开始进行文件的复制
InputStream input = context.getResources().openRawResource(rawid); // 获取资源文件raw
// 标号
try {
FileOutputStream out = new FileOutputStream(file1); // 文件输出流、用于将文件写到SD卡中
// -- 从内存出去
byte[] buffer = new byte[1024];
int len = 0;
while ((len = (input.read(buffer))) != -1) { // 读取文件，-- 进到内存
out.write(buffer, 0, len); // 写入数据 ，-- 从内存出
}
input.close();
out.close(); // 关闭流
} catch (Exception e) {
e.printStackTrace();
}
}5、定义一个printer（）方法，将数据存入到指定的Excel单元格中
private void printer() {
try {
saveFile("radiate1.xls", this, R.raw.radiate1);//文件目录res/raw
//现场检查记录
Log.e("ooo","aaa");
String aafileurl = Environment.getExternalStorageDirectory() + "/inspection/radiate1.xls";
String bbfileurl = Environment.getExternalStorageDirectory() + "/inspection/radiate1_printer.xls";
Workbook rwb = Workbook.getWorkbook(new File(aafileurl));
WritableWorkbook wwb = Workbook.createWorkbook(new File(bbfileurl), rwb);// copy
WritableSheet wws = wwb.getSheet(0);
/**

WritableCell wc1_2 = wws.getWritableCell(1, 2);
WritableCell wc1_3 = wws.getWritableCell(1, 3);
WritableCell wc1_4 = wws.getWritableCell(1, 4);
WritableCell wc1_5 = wws.getWritableCell(1, 5);

WritableCell wc1_14 = wws.getWritableCell(1, 14);
WritableCell wc1_15 = wws.getWritableCell(1, 15);
WritableCell wc1_16 = wws.getWritableCell(1, 16);
WritableCell wc4_10 = wws.getWritableCell(4, 10);
WritableCell wc4_11 = wws.getWritableCell(4, 11);
WritableCell wc4_12 = wws.getWritableCell(4, 12);
WritableCell wc5_5 = wws.getWritableCell(5, 5);
WritableCell wc5_6 = wws.getWritableCell(5, 6);
WritableCell wc6_13 = wws.getWritableCell(6, 13);
WritableCell wc7_10 = wws.getWritableCell(7, 10);
WritableCell wc7_11 = wws.getWritableCell(7, 11);
WritableCell wc10_10 = wws.getWritableCell(10, 10);
WritableCell wc10_11 = wws.getWritableCell(10, 11);

WritableCell wc16_12 = wws.getWritableCell(16, 12);
WritableCell wc16_11 = wws.getWritableCell(16, 11);
WritableCell wc13_13 = wws.getWritableCell(13, 13);
WritableCell wc13_14 = wws.getWritableCell(13, 14);
WritableCell wc14_8 = wws.getWritableCell(14, 8);
WritableCell wc10_9 = wws.getWritableCell(10, 9);
WritableCell wc11_5 = wws.getWritableCell(11, 5);
WritableCell wc14_2 = wws.getWritableCell(14, 2);
WritableCell wc14_3 = wws.getWritableCell(14, 3);
WritableCell wc14_4 = wws.getWritableCell(14, 4);
