在文本文件android中添加换行符

Question

大家好我正在使用此代码将文本附加到txt文件中。任何人都可以指导我如何为此案例添加换行符

fOut = new FileOutputStream(new File(myFilePath + BlueFreeConstants.logFileName), true);
osw = new OutputStreamWriter(fOut);
osw.append("<< " + values + " >>");
osw.flush();
osw.close();
fOut.close();

Answer 1

String separator = System.getProperty("line.separator");
fOut = new FileOutputStream(new File(myFilePath + BlueFreeConstants.logFileName), true);
osw = new OutputStreamWriter(fOut);
osw.append("<< " + values + " >>");
osw.append(separator); // this will add new line ;
osw.flush();
osw.close();
fOut.close();

Answer 2

osw.append('\n')。这就是你要找的东西吗？

Answer 3

osw.append("<<"+values+">>\n");

Answer 4

这是我创建多行文本文件的代码：

FileOutputStream fos=null;
    OutputStreamWriter osw;
    try {
    fos = openFileOutput("login.txt",Context.MODE_PRIVATE);
    fos.write(("Line One").getBytes());
    osw = new OutputStreamWriter(fos);
    osw.append("\r\n");
    osw.append("Line Two");
    osw.flush();
    osw.close();
    fos.flush();
    fos.close();
} catch (Exception e) {}
