设置以时间命名的文件路径及名称

private String getOutputMediaPath() {
        java.util.Date date = new java.util.Date();
        String timeTemp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(date.getTime());
        //File storageFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath());
        File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator +
                "VID_" + timeTemp + ".mp4");
        Log.e("Error", "getOutputMediaPath file path---"+file.getAbsolutePath());
        return file.getAbsolutePath();
