体温上报软件开发

这是导出栏，

根据获得的文件路径，

在手机文件复制并打开，

可以得到xlsx表格，

查看录入的信息内容

路径获取函数：

public void exportExcel() {

    file = new File(getSDPath(this) + "/Record2");
    makeDir(file);
    ExcelUtils.initExcel(file.toString() + "/14天健康登记表.xlsx");
    fileName = getSDPath(this) + "/Record2/14天健康登记表.xlsx";
    ExcelUtils.writeObjListToExcel(getRecordData(), fileName, this);
}

/**
 * 将数据集合 转化成ArrayList<ArrayList<String>>
 * @return
 */
private  ArrayList<ArrayList<String>> getRecordData() {
    recordList = new ArrayList<>();
    for (int i = 0; i <students.size(); i++) {
        temBean student = students.get(i);
        ArrayList<String> beanList = new ArrayList<String>();
        beanList.add(student.getTime());
        beanList.add(student.getAddress());
        beanList.add(student.getTemperature());
        beanList.add(student.getAddition());
        recordList.add(beanList);
    }
    return recordList;
}

//获取sd卡地址
public static String getSDPath(Context context) {
    File sdDir = null;
    boolean sdCardExist = Environment.getExternalStorageState().equals(
            Environment.MEDIA_MOUNTED);// 判断sd卡是否存在

    if (sdCardExist) {
        if (Build.VERSION.SDK_INT>=29){
            //Android10之后
            sdDir = context.getExternalFilesDir(null);
        }else {
            sdDir = Environment.getExternalStorageDirectory();// 获取SD卡根目录

        }
    } else {
        sdDir = Environment.getRootDirectory();// 获取跟目录
    }
    return sdDir.toString();
}


public  void makeDir(File dir) {
    if (!dir.getParentFile().exists()) {
        makeDir(dir.getParentFile());
    }
    dir.mkdir();
