读取SD卡文件信息，添加到ListView中显示出来:

ListView取得SD文件信息的代码:

List<Map<String, Object>> list = new ArrayList<Map<String, Object>>(); String sDStateString = Environment.getExternalStorageState(); if (sDStateString.equals(Environment.MEDIA_MOUNTED)) { try { File SDFile = Environment.getExternalStorageDirectory(); File sdPath = new File(SDFile.getAbsolutePath()); if (sdPath.listFiles().length > 0) { for (File file : sdPath.listFiles()) { Map<String, Object> map = new HashMap<String, Object>(); map.put("text_content", file.getName()); //get filename list.add(map); } } } catch (Exception e) { // } } return list;
