android学习:自动识别文本文件编码格式

    /**

     * 判断文件的编码格式

     * @param fileName :file

     * @return 文件编码格式

     * @throws Exception

     */

    public static String codeString(String fileName) throws Exception{

        BufferedInputStream bin = new BufferedInputStream(

        new FileInputStream(fileName));

        int p = (bin.read() << 8) + bin.read();

        String code = null;

        

        switch (p) {

            case 0xefbb:

                code = "UTF-8";

                break;

            case 0xfffe:

                code = "Unicode";

                break;

            case 0xfeff:

                code = "UTF-16BE";

                break;

            default:

                code = "GBK";

        }

        

        return code;

    }

 

有了这个函数，妈妈再也不用担心我的文本文件打开是乱码了,O(∩_∩)O哈哈~
