java - 读取文本文件时检测新行 - Android

Question

我有一个简单的应用程序，它读取一个 txt 文件并将其放入 EditText View 中。 一切都很好，除了我无法从 txt 文件中检测到换行符并将其替换为“\n”。

for example : I have this text in my file

    this
    is
    a
    file
    with
    newline

but this is what I get in the Edittext view:

    thisisafilewithnewline.

这是我的代码:

private String onFileClick(Option o){

    StringBuilder text = new StringBuilder();//--read text from file---
    String filePath = o.getPath();
    String CHARSET = "ISO-8859-1";
    String fileType = MimeTypeMap.getFileExtensionFromUrl(filePath);
    String NOT_TXT = "NOT TXT FILE";

    try{
        BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(filePath), CHARSET));
        String line;
        while((line = br.readLine()) != null){
            text.append(line.replaceAll("\r\n", "\n"));
        }
        br.close();
    }catch (FileNotFoundException e) {
        Log.e("login activity", "File not found: " + e.toString());
    } catch (IOException e) {
        Log.e("login activity", "Can not read file: " + e.toString());
    }

    if(fileType.equals("txt"))
        return text.toString();
    else
        return NOT_TXT;
}

我需要帮助

Answer 1

text.append(line+"\n");// this will add new line into your string after reading

这就是你想要做的吗？
