Question

我有一个txt文件的链接。我想通过按下按钮将其保存到手机中。但我没有得到。请帮助！

  void writeFile() throws IOException {
        File myFile = new File("/sdcard/mysdfile.txt");
        myFile.createNewFile();
        HttpURLConnection httpURLConnection = null;
        assert httpURLConnection != null;
        FileOutputStream fOut = new FileOutputStream(myFile);
        OutputStreamWriter myOutWriter = new OutputStreamWriter(fOut);
        myOutWriter.append("my text");
        myOutWriter.close();
        fOut.close();
        Toast.makeText(getBaseContext(), "Done writing SD 'mysdfile.txt'", Toast.LENGTH_SHORT).show();
    }

仅代替“我的文字”我需要“％D0％96％D0％B8％D0％B7％D0％BD％D1％8C％D0％BE％D0％B4％D0％B8％D0％BD％ D0％BE％D0％BA％D0％BE％D0％B3％D0％BE_％D0％B4％D0％B5％D1％80％D0％B5％D0％B2％D1％86％D0％B0。％D0％A0％D0％B0％D1％81％D1％81％D0％BA％D0％B0％D0％B7％D1％8B.txt“＆GT; HTTP：//www.e-reading.bz/ txt.php / 1002963 /％D0％9C％D0％B8％D1％88％D0％B8％D0％BD -_％D0％96％D0％B8％D0％B7％D0％BD％D1 ％8C_％D0％BE％D0％B4％D0％B8％D0％BD％D0％BE％D0％BA％D0％BE％D0％B3％D0％BE_％D0％B4％D0％B5％D1％80 ％D0％B5％D0％B2％D1％86％D0％B0 ._％D0％A0％D0％B0％D1％81％D1％81％D0％BA％D0％B0％D0％B7％D1％8B .TXT“

我的解决方案

 URL url = new URL(my link); //you can write here any link
        URLConnection ucon = url.openConnection();
        InputStream is = ucon.getInputStream();
        BufferedInputStream bis = new BufferedInputStream(is);
        ByteArrayBuffer baf = new ByteArrayBuffer(5000);
        int current = 0;
        while ((current = bis.read()) != -1) {
            baf.append((byte) current);
        }
        FileOutputStream fos = new FileOutputStream("/sdcard/mysdfile.txt");
        fos.write(baf.toByteArray());
        fos.flush();
        fos.close();
        Toast.makeText(getBaseContext(), "Done writing SD 'mysdfile.txt'", Toast.LENGTH_SHORT).show();
