Android文件或文件夹压缩成.zip格式的压缩包

下面是压缩文件和文件夹的方法：

  /**
     * 压缩文件和文件夹
     *
     * @param srcFileString 要压缩的文件或文件夹
     * @param zipFileString 压缩完成的Zip路径
     * @throws Exception

        File file = new File(srcFileString);
        //压缩
        LogUtils.LOGE("---->"+file.getParent()+"==="+file.getAbsolutePath());
        ZipFiles(file.getParent()+ File.separator, file.getName(), outZip);
        //完成和关闭
        outZip.finish();
