使用Apache POI在Android Studio中打开文件并在项目中打开文件

Question

I have placed an xlsx file named menuA as you may see in the photo below:

But I fear that I am not accessing it correctly using FileInputStream

FileInputStream file = null;
        try {
            file = new FileInputStream(new File("menuA.xlsx"));
        } catch (Exception e) {
            e.printStackTrace();
        }


    XSSFWorkbook workbook=null;
    try {
        workbook = new XSSFWorkbook(file);
    } catch (IOException e) {
        e.printStackTrace();
    }

    //create a sheet object
    XSSFSheet sheet = workbook.getSheetAt(0);

    //that is for evaluate the cell type
    FormulaEvaluator formulaEvaluator = workbook.getCreationHelper().createFormulaEvaluator();

I have moved from NetBeans to Android Studio, where my code works perfectly in Android Studio.

Answer 1

You can put the same file in the assets folder (The place to put static resources for easy access) and access those assets as following

InputStream is = getAssets().open("menuA.xlsx");

EDIT:

Since the library that you are using FileInputStream , You can copy the file over to the application's private data storage, which is getExternalFilesDir(null) . and access the file from there.
