检测Android中rss源的编码

我正在尝试使用XmlPullParser解析XML

我想获取提要的编码

比如说

    <?xml version="1.0" encoding="ISO-8859-1"?>

及

这里有两种不同的编码我想检测编码

谁能

---

我已经尝试过

getInputEncoding（）

您可以这样做： XmlPullparser parser=新的XmlPullparser（inputstream in，null）；

---

这将自动检测编码

您可以这样做：

//URL_FEED Example: http://jovemnerd.ig.com.br/feed/rss/
final HttpGet httpget = new HttpGet(URL_FEED);

//Connect 
final HttpResponse response = httpclient.execute(httpget);

//Get Entity connection
HttpEntity entity = response.getEntity();

//Get InputStream
InputStream feed = entity.getContent();

XmlPullparser parser=新的XmlPullparser（inputstream in，null）； 这将自动检测编码

//URL_FEED Example: http://jovemnerd.ig.com.br/feed/rss/
final HttpGet httpget = new HttpGet(URL_FEED);

//Connect 
final HttpResponse response = httpclient.execute(httpget);

//Get Entity connection
HttpEntity entity = response.getEntity();

//Get InputStream
InputStream feed = entity.getContent();

@我补充说，米苏萨克comment@leus谢谢你的代码，我将测试它是否工作，将标记为正确，但给你+1帮助我，非常感谢：）@leus我有一个如下的xml One test Des test.com/Two test Des test.com/但是根据你的代码，编码返回空值。我从其他xml中获得UTF-8，这些xml有“UTF-8”，但没有“iso-8859-1”。你能帮我吗check@MishuSarker我更新了detect Encoding from head xml:

String GetEncodingFromEntity（HttpEntity实体）

@MishuSarker我添加了comment@leus谢谢你的代码，我将测试它是否工作，将标记为正确，但给你+1帮助我，非常感谢：）@leus我有一个如下的xml One-Test Des-Test.com/Two-Test Des-Test.com/但是根据您的代码，编码返回null。我从其他xml中获得UTF-8，这些xml有“UTF-8”，但没有“iso-8859-1”。你能帮我吗check@MishuSarker我更新了detect enconding from head xml:

String getencondingfromtentity（HttpEntity entity）

您读过这个吗？谢谢你的推荐。我会检查一下，让你知道：）你读过这个吗？谢谢你的推荐。我会检查并让您知道：）

//Convert InputStrean to InputSource

    source.setEncoding(getEncondingFromEntity(entity));
}

/*Now your InputSource have the correct enconding, then use "source" in your parse. Ex:*/
