Android开发对压缩文件的处理

本篇文章主要讲解有关压缩文件的处理：在开发中我们不免会遇到上传多个文件到服务器，这个时候我们就要用到压缩文件，将压缩到的文件上传到服务器，就非常的方便,下面是压缩文件的工具类，以供参考:

public class ZipUtils {
    private static boolean isSuccess = false;
    public static boolean isSuccess() {
        return isSuccess;
    }

    /**
     * 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
     */
    public static void ZipFolder(String srcFileString, String zipFileString,String zipName)  {
        //创建ZIP
        ZipOutputStream outZip = null;
        try {
            //创建文件
            File file = new File(srcFileString);
            File outPath = new File(zipFileString);
            if (!outPath.exists()){
                outPath.mkdirs();
            }
            outZip = new ZipOutputStream(new FileOutputStream(new File(outPath, zipName)));
            //压缩
            ZipFiles(file.getParent() + File.separator, file.getName(), outZip);
            isSuccess = true;
        } catch (Exception e) {
            isSuccess = false;
            e.printStackTrace();
        } finally {
            //完成和关闭
            if (outZip != null) {
                try {
                    outZip.finish();
                    outZip.close();
                }catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
