使用UTF-8写入文件 [英] Write file with UTF-8

问题描述

我正在尝试使用utf-8编码编写文件.我想在Excel中的PC上看到此文件我看了足够的实现此代码的示例.但是我没有达到预期的结果.我的代码:

I'm trying to write a file with utf-8 encoding. This file I would like to see on PC in Excel I've looked at enough examples of implementing this code. But I did not achieve the desired results. My code:

    String baseDir = android.os.Environment.getExternalStorageDirectory().getAbsolutePath();
    String fileName = etName.getText().toString() + ".csv";
    String filePath = baseDir + File.separator + fileName;
    File sdCardFile = new File(filePath);

    String DATE = "01.04.2017 - 30.04.2017";
    String NEW_LINE = "\n";
    String NEW_CELL = ";";
    String HEADER = "Место;" +
            "Фамилия ИО;" +
            "Цикл ТО-1;" +
            "Культурное состояние л-ва;" +
            "Посещение тех.занятий;" +
            "Расшифровка лент;" +
            "Охрана труда;" +
            "Отказы";

BufferedWriter bufferedWriter = new BufferedWriter
                (new OutputStreamWriter(new FileOutputStream(sdCardFile), "UTF-8"));
        bufferedWriter.write(DATE);
        bufferedWriter.write(NEW_LINE);
        bufferedWriter.write(HEADER);
        for(int i = 0; i < machinists.size(); i ++){
            bufferedWriter.write(NEW_LINE);
            bufferedWriter.write(String.valueOf(i+1));
            bufferedWriter.write(NEW_CELL);
            bufferedWriter.write(machinists.get(i).getLastName());
            bufferedWriter.write(NEW_CELL);
            bufferedWriter.write(String.valueOf(machinists.get(i).getPoints().getTo()));
            bufferedWriter.write(NEW_CELL);
            bufferedWriter.write(String.valueOf(machinists.get(i).getPoints().getCultureState()));
            bufferedWriter.write(NEW_CELL);
            bufferedWriter.write(String.valueOf(machinists.get(i).getPoints().getTechnicalSessions()));
            bufferedWriter.write(NEW_CELL);
            bufferedWriter.write(String.valueOf(machinists.get(i).getPoints().getTapeTranscript()));
            bufferedWriter.write(NEW_CELL);
            bufferedWriter.write(String.valueOf(machinists.get(i).getPoints().getOt()));
            bufferedWriter.write(NEW_CELL);
            bufferedWriter.write(String.valueOf(machinists.get(i).getPoints().getFault()));
            bufferedWriter.write(NEW_CELL);
        }
        bufferedWriter.close();
    }

但是我看到了.

为什么?

推荐答案

我解决了这个问题！

FileOutputStream os = new FileOutputStream(sdCardFile);
        os.write(0xef);<-!!!!!!!!
        os.write(0xbb);<-!!!!!!!!
        os.write(0xbf);<-!!!!!!!!
        CSVWriter writer = new CSVWriter(new OutputStreamWriter(os), ';');
writer.writeNext(HEADER);
...
writer.writeNext('something data');
writer.close();
