xlsx 通过 apache poi 读取

Question

我只需要从我的 sd 卡中 select 一个 XLSX 文件并通过 apache poi 读取它。这是我对 sd 卡的意图调用并选择 xlsx 文件

        Intent intent = new Intent();
        intent.setType("*/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(Intent.createChooser(intent, "Complete action using"), PICK_FROM_FILE);
    }

这是接收 selected .xlsx 文件路径的代码这里是生成的错误我认为是在调用工作簿时发生的，但我无法清除它

    public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == PICK_FROM_FILE && resultCode == RESULT_OK) {


       // File file = new File(Environment.getExternalStorageDirectory(), data.getData().toString());
        Uri path =data.getData();
        ContentResolver cr=this.getContentResolver();
        File fpath=new File(path.toString());


        try {
            //imputStream
            InputStream myfile=cr.openInputStream(path);
            Log.e("myapp","here");
            //Workbooh
            Workbook wrk=new HSSFWorkbook(myfile);


            //sheet
            Sheet firstsheet=wrk.getSheetAt(0);

            //RowIterator
            Iterator<Row> iterator=firstsheet.iterator();
            while(iterator.hasNext())
            {
                Row next=iterator.next();

                //CellIterator
                Iterator<Cell> cellIterator=next.cellIterator();
                while(cellIterator.hasNext())
                {
                    Cell cell=cellIterator.next();

                    switch (cell.getCellType())
                    {
                        case Cell.CELL_TYPE_STRING:
                            Toast.makeText(getApplicationContext(),cell.getStringCellValue()+" ",Toast.LENGTH_SHORT).show();
                            break;
                        case Cell.CELL_TYPE_NUMERIC:
                            Toast.makeText(getApplicationContext(),cell.getNumericCellValue()+" ",Toast.LENGTH_SHORT).show();
                    }
                }

            }


        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }


    }


    }

摆脱捕获 - e.printStackTrace()，这可能隐藏了您获得的实际异常。你最好回顾一下如何正确记录这些。

并查看 https://github.com/andruhon/android5xlsx，它为在 Android 上使用 Apache POI 时出现的问题提供了一些解决方法。
