直接就把項目中的方法貼出來吧
/** * 讀出城市列表文件*/ private String readCityFile() { File file02 = new File(path_xinfu, "/cityList.json"); FileInputStream is = null; StringBuilder stringBuilder = null; try { if (file02.length() != 0) { /** * 文件有內容才去讀文件*/ is = new FileInputStream(file02); InputStreamReader streamReader = new InputStreamReader(is); BufferedReader reader = new BufferedReader(streamReader); String line; stringBuilder = new StringBuilder(); while ((line = reader.readLine()) != null) { // stringBuilder.append(line); stringBuilder.append(line); } reader.close(); is.close(); } else { mLoadingLayout.setStatus(LoadingLayout.Empty); } } catch (Exception e) { e.printStackTrace(); } return String.valueOf(stringBuilder); }以上這篇java讀取文件內容為string字符串的方法就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持武林網。
