体温上报APP２.１

1、今日进度表：

2、今日目标：

完成第二阶段的生成导出excel表格

3、今日完成：

１、导入ｃｌａｓｓ．ｘｌｓ包

２、建立excel工具类ExcelUtil，定义要导出表格的样式

                }
                for(int t=6;t<20;t++){
                    sheet.mergeCells(5, t, 6, t); // 合并单元格-备注
                }
                writebook.write();

                Toast.makeText(c, "Excel导出成功", Toast.LENGTH_SHORT).show();
            } catch (Exception e) {
                e.printStackTrace();
            } finally {
                if (writebook != null) {
                    try {
                        writebook.close();
                    } catch (Exception e) {
                        e.printStackTrace();
                    }

                }
                if (in != null) {
                    try {
                        in.close();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
            }

        }
    }
}

 ３、建立实体类Situation　用于存储体温上报中的信息，用以导出到ｅｘｃｅｌ　表格中

package com.example.reporttemperature;



public class Situation {
    private String health;
    private String date;
    private String address;
    private String temperature;


    public String getHealth() {
        return health;
    }

    public void setHealth(String health) {
        this.health = health;
    }

    public String getDate() {
        return date;
    }

    public void setDate(String date) {
        this.date = date;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getTemperature() {
        return temperature;
    }

    public void setTemperature(String temperature) {
        this.temperature = temperature;
    }



    public Situation(){

    }

    public Situation(String date,String temperature,String address,String health){

        this.temperature = temperature;
        this.address = address;
        this.date = date;
        this.health = health;


    }

}

５、CreateActivity用于生成excel表格，并将数据放入

package com.example.reporttemperature;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;

    private List<Situation> students;
    private File file;
    private String fileName;
    private EditText ed,et ;
    private String ID_number;
    private MyOpenHelper helper=new MyOpenHelper(this);
    private String[] r;
    private String s;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_create);

        Intent intent=getIntent();
        ID_number=intent.getStringExtra("IDnumber");

        r=get_phone(ID_number);
       String [][] tem=get_tem(r[0]);

        //模拟数据集合
        students = new ArrayList<>();
        for (int i = 0; i<14; i++) {
            students.add(new Situation(tem[i][0],tem[i][2],tem[i][1],"健康"));
        }
        //导出excel表
        exportExcel();
        ed=findViewById(R.id.path);
        ed.setText("Excel表格已导出至："+getSDPath(this));
        et=findViewById(R.id.m);
        //et.setText(s+"");


    }

    /**
     * 导出excel
     */
   public void exportExcel() {

        file = new File(getSDPath(this) + "/Record2");
        makeDir(file);
        ExcelUtil.initExcel(file.toString() + "/14天健康登记表.xlsx");
        fileName = getSDPath(this) + "/Record2/14天健康登记表.xlsx";
        ExcelUtil.writeObjListToExcel(getRecordData(), fileName, this,r[2],r[0],ID_number,r[1]);
    }

    /**
     * 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++) {
            Situation student = students.get(i);
            ArrayList<String> beanList = new ArrayList<String>();
            beanList.add(student.getDate());
            beanList.add(student.getTemperature());
            beanList.add(student.getHealth());
            beanList.add(student.getAddress());
            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(

                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();
    }

    //按照学号查找手机号
    private String[] get_phone(String text1){
        String newName="",newPhone="",newClass="";
        String []result=new String[3];
        SQLiteDatabase db=helper.getReadableDatabase();
        Cursor cursor = db.rawQuery("select * from user where idNumber = ? ", new String[]{text1});

        while (cursor.moveToNext()) {
            newName = cursor.getString(cursor.getColumnIndex("name"));
            newPhone = cursor.getString(cursor.getColumnIndex("phone"));

        }
        cursor.close();
        db.close();
        result[0]=newName;
        result[1]=newPhone;
        result[2]=newClass;

        return result;

    }

//获取体温数据库中信息
    public String[][] get_tem(String text2) {

        String[][] stringArr2=new String[100][3];
