RSS閱讀器發送HTML字符

RSS閱讀器發送HTML字符，如「＃8220;」所以當飼料是「嘿＃8220」時該應用程序只顯示「嘿」但我知道爲什麼。我嘗試了諸如Html.fromHtml之類的東西，但它確實沒有工作。有沒有人看到錯誤？感謝答案RSS閱讀器發送HTML字符

更改編碼可以幫助你。嘗試不同的字符編碼。 – Tugrul

RSS Feed編碼？ –

解析器編碼。 – Tugrul

InputSource myInputSource = new InputSource(rssUrl.openStream()); 
     myXMLReader.parse(myInputSource);

設置一個編碼輸入源或流。 This sample cod e可以幫助你。
