從res/raw文件夾中讀取文本文件

Question

我試圖從res中的原始文件夾中使用final Scanner input = new Scanner(new File(R.raw.xmlsource)).useDelimiter("[\\;]+");讀取文本文件，但由於資源ID在R.java文件中爲int，我的代碼在下面

編輯做了一些改動下面我的代碼，仍然不能運行，但使用調試器，我可以告訴大家，它實際上讀取文件，這個問題似乎是在String[] RssLinksArray = readLine.split("[\\;]+");其中代碼終止，我不能爲了我的生活找出原因。我也附加logcat。

任何幫助將非常感激。

Answer 1

InputStream inputStream = getResources().openRawResource(R.raw.xmlsource); 
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
