private static final String MOUNTS_FILE = "/proc/mounts";public static boolean isMounted(String path) {        boolean blnRet = false;        String strLine = null;        BufferedReader reader = null;        try {            reader = new BufferedReader(new FileReader(MOUNTS_FILE));            while ((strLine = reader.readLine()) != null) {                if (strLine.contains(path)) {                    blnRet = true;                    break;                }            }        } catch (Exception e) {            e.printStackTrace();        } finally {            if (reader != null) {                try {                    reader.close();                } catch (IOException e) {                    e.printStackTrace();                }                reader = null;            }        }        return blnRet;    }

android系統根目錄下有/proc/mounts檔案，裡面有所有掛載資訊，用以上方法應該可以判斷某個路徑是否掛載
