今天學習下Android中將資料儲存到 excel 表中，本文是在下面文獻基礎上進行的復現：
https://blog.csdn.net/linzhenxiang123/article/details/53730439

一、MainActivity 程式碼

public class MainActivity extends AppCompatActivity implements View.OnClickListener{

    private EditText name = null;
    private EditText sex = null;
    private EditText phone = null
 
;
    private EditText address = null;
    private Button button = null;
    private ExcelUtil excelUtil = null;

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

        name = (EditText)findViewById(R.id.name);
        sex = (EditText)findViewById(R.id.sex);
        phone = (EditText)findViewById(R.id.phone);
        address = (EditText)findViewById(R.id.address);
        button = (Button) findViewById(R.id.button);
        button.setOnClickListener(this
 
);

        excelUtil = new ExcelUtil(MainActivity.this,"/sdcard/test.xls");
    }

    @Override
    public void onClick(View v) {
        String name1 = name.getText().toString();
        String sex1 = sex.getText().toString();
        String phone1 = phone.getText().toString();
        String address1 = address.getText().toString();
        excelUtil.writeToExcel(name1,sex1,phone1,address1);
    }
}
 

二、 Excel 操作
下面是 excel 操作的主要程式碼

import android.app.Activity;
import android.widget.Toast;

import java.io.File;

import jxl.Workbook;
import jxl.write.Label;
import jxl.write.WritableSheet;
import jxl.write.WritableWorkbook;

public class ExcelUtil {

        private WritableWorkbook wwb;
        private File excelFile;
        private Activity activity;

        public ExcelUtil(Activity activity, String excelPath) {
            this.activity = activity;
            excelFile = new File(excelPath);
            createExcel(excelFile);
        }

        public void createExcel(File file) {
            WritableSheet ws = null;
            try {
                if (!file.exists()) {
                    wwb = Workbook.createWorkbook(file);
                    ws = wwb.createSheet("sheet1", 0);

                    Label lbl1 = new Label(0, 0, "姓名");
                    Label lbl2 = new Label(1, 0, "性別");
                    Label lbl3 = new Label(2, 0, "電話");
                    Label lbl4 = new Label(3, 0, "地址");

                    ws.addCell(lbl1);
                    ws.addCell(lbl2);
                    ws.addCell(lbl3);
                    ws.addCell(lbl4);

                    wwb.write();
                    wwb.close();
                }

            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        public void writeToExcel(Object... args) {

            try {
                Workbook oldWwb = Workbook.getWorkbook(excelFile);
                wwb = Workbook.createWorkbook(excelFile, oldWwb);
                WritableSheet ws = wwb.getSheet(0);

                int row = ws.getRows();
                Label lab1 = new Label(0, row, args[0] + "");
                Label lab2 = new Label(1, row, args[1] + "");
                Label lab3 = new Label(2, row, args[2] + "");
                Label lab4 = new Label(3, row, args[3] + "");
                ws.addCell(lab1);
                ws.addCell(lab2);
                ws.addCell(lab3);
                ws.addCell(lab4);

                wwb.write();
                wwb.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
}

三、 jar包
CSDN 上有免積分的 jxl jar 可下載

四、問題
1.容易出現問題 bug ：the input file was not found ；可以嘗試 直接在桌面上建立 xls檔案，並匯入到手機準備放置的路徑下（即不通過程式碼建立xls檔案）;

2.發現將 txt 檔案按照一定的個數儲存，然後txt 可以直接匯入到 excel，感覺效果是一樣的；如果沒有非常必須的需求（感覺這個直接儲存excel問題還是太多），可以儲存先為txt (桌面上用excel 重新載入下就可以了，可以檢視 txt匯入excel)
