Question

我有一个我尝试拆分的字符串。以下代码可以使用

lsSagor = "some text\n Some more text\n More text~Text again\n Text\n text~Some text ..."

final String[] laList = lsSagor.split("~");

String[] laSaga = laList[0].split("\n");

给出：

laSaga[0] => some text

laSaga[1] => some more text

laSaga[2] => More text

但是如果我下载文本文件，则无法拆分并给出：

laSaga[0] => "some text\n Some more text\n More text"

所以看起来第一次拆分工作，但不是第二次。

以下是我用来下载文件的代码

String lsSagor = getFileFromUrl(BASEURL+"/sagor.txt");

public static String getFileFromUrl(String url) 
{
    InputStream content = null;
    try 
    {
        HttpGet httpGet = new HttpGet(url);
        HttpClient httpclient = new DefaultHttpClient();
        // Execute HTTP Get Request
        HttpResponse response = httpclient.execute(httpGet);
        content = response.getEntity().getContent();
    }
    catch (Exception e) 
    {
        //handle the exception !
    }
    BufferedReader rd = new BufferedReader(new InputStreamReader(content), 4096);
    String line;
    StringBuilder sb =  new StringBuilder();
    try {
        while ((line = rd.readLine()) != null) {
                sb.append(line);
        }
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    try {
        rd.close();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return sb.toString();


}

Answer 1

From the documentation

我认为您不会发现您的字符串包含要拆分的任何换行符，您需要这样做

       while ((line = rd.readLine()) != null) {
            sb.append(line);
            sb.append("\n");
       }

要做到这一点，我确信有一种更简单的方法可以直接阅读新行，而且一开始就是这样。

您好我认为问题出在String.split（）函数中老方法但工作:)

    public static String[] splitString(String str, char separator)
{
    String[] retVal = null;

    int length = str.length();
    int size = 1;

    int jIndx = 0;
    int expressionLength = 0;

    while ((jIndx = str.indexOf(separator, jIndx + 1)) != -1)
    {
        size++;
    }

    retVal = new String[size];
    jIndx = 0;

    char[] charArray = str.toCharArray() ;
    for (int index = 0; index < length; index++)
    {
        if (charArray[index] == separator)
        {
            retVal[jIndx] = str.substring(index - expressionLength, index);
            jIndx++;
            expressionLength = 0;
        }
        else
            expressionLength++;


        if (index + 1 == length)
        {
            retVal[jIndx] = str.substring(index + 1 - expressionLength, index + 1);
        }
    }

    return retVal;
}

这是（不那么漂亮）解决方案

lsSagor = "some text# Some more text# More text~Text again\n Text# text~Some text ..."

String lsSagor = getFileFromUrl(BASEURL+"/sagor.txt");

 final String[] laList = lsSagor.split("~");

    giAntalSagor = laList.length;

    String[] laSaga = laList[0].split("#");

    final String[] guiLaList = new String[giAntalSagor];
    for (int i = 0; i < giAntalSagor; i++)
    {
        guiLaList[i] = laList[i].replaceAll("#", "\n");
    }

guiLaList用于布局“\ n”，另一个列表laList用于获取我想要的信息。
