Apache Poi 安卓

Question

我在 Android 应用程序中使用 Apache Poi，但 HSSFWorkbook 有问题。

我只想读取 Android 平板电脑内存中的 Excel 文件。 （在 Android 应用中显示数据）

我的代码：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);



try {
    AssetManager assetManager = this.getAssets();
    InputStream input = assetManager.open("test42.XLS");

    HSSFWorkbook classeur = new HSSFWorkbook(input);

    //HSSFSheet feuille = classeur.getSheetAt(0);

    //Cell cell = feuille.getRow(1).getCell(1);

    //String value = cell.getStringCellValue();

    TextView tv = new TextView(this);


    tv.setText("Test");

    setContentView(tv);

} catch (IOException e) {
    e.printStackTrace();
    System.out.println("prob");

}

}

为 xls 文件尝试以下操作：

   try {
                InputStream caInput = new BufferedInputStream(getAssets().open(
                        "ie_data.xls"));
                HSSFWorkbook workbook = new HSSFWorkbook(caInput);
                HSSFSheet feuille = workbook.getSheetAt(0);

                Cell cell = feuille.getRow(1).getCell(1);

                String value = cell.getNumericCellValue()+"";
                Toast.makeText(getApplicationContext(), value, Toast.LENGTH_LONG)
                        .show();
            } catch (IOException e1) {
                // TODO Auto-generated catch block


e1.printStackTrace();
        }

对于 xlsx ：

1st - 导入以下 jar 文件：

(dom4j-1.6.1.jar , poi-ooxml-3.5-FINAL.jar , poi-ooxml-schemas-3.8-beta4.jar , poi-3.9-20121203.jar , xmlbeans-2.3.0.jar) .

第二 - 在 try catch 块中执行以下操作：

如果您使用的是 File 对象，请执行以下操作：

File file = new File("path");



        InputStream caInput = new FileInputStream(file);

如果您正在使用 inputStram 读取文件，请执行以下操作：

InputStream caInput = new BufferedInputStream(getAssets().open(
                            "ie_data.xlsx"));

            XSSFWorkbook workbook = new XSSFWorkbook(caInput);
            XSSFSheet feuille = workbook.getSheetAt(0);

            Cell cell = feuille.getRow(0).getCell(0);

            String value = cell.getStringCellValue() + "";

            System.out.print("hello = " + value); 

但请注意，我根据我的 xslx 文件获取了 StringCellValue，您应该检查您的 xlsx 文件，看看它是字符串并使用 getStringCellValue() 还是 Numeric 并使用 getNumericCellValue()。

请给我一些反馈

希望对您有所帮助。

 WorkbookFactory.create(fis);

使用 Workbook 工厂创建 Workoook。

Answer 3

最后我在平板电脑中找到了我的文件的路径（以避免使用资产）： "/storage/sdcard0/Documents/test42.xls"

应用程序找到了文件，但是在创建HSSFWorkbook时仍然出现问题，出现异常“01-29 16:15:21.329: W/System.err(13127): java.io.IOException:标头签名无效；读取 0x0010000000060409，预期为 0xE11AB1A1E011CFD0"

我不明白这个异常，但至少我找到了我的文件 Enplacement

我的代码：

    try {
        File file = new File("/storage/sdcard0/Documents/test42.xls");
        FileInputStream input = new FileInputStream(file);





        HSSFWorkbook classeur =  new HSSFWorkbook(input);

        //HSSFSheet feuille = classeur.getSheetAt(0);

        //Cell cell = feuille.getRow(1).getCell(1);

        //String value = cell.getStringCellValue();


        String path = Environment.getExternalStorageDirectory().getAbsolutePath();

        TextView tv = new TextView(this);

        tv.setText(path );

        setContentView(tv);

    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
