在解压缩文件夹中遇到问题 - 从文件夹到文件夹的文件

Question

下面是我将文件夹解压缩到目标文件夹和方法定义的方法

unzip(filepath, unzipLocation);

这是我解压缩文件的方法这个方法工作文件但是当我的zip文件像a.zip那样有文件夹2文件夹（即abc1，abc2）和文件夹abc1文件夹而且它有文件时出现问题帮助我

private void unzip(String src, String dest) {
        String _location = "";

            while ((zipEntry = zipInputStream.getNextEntry()) != null) {
                String zipEntryName = zipEntry.getName();
                String name = dest.substring(dest.lastIndexOf("/") - 1);

public static void unZipIt（String zipFile，String outputFolder）{

    byte[] buffer = new byte[1024];
    //mm    System.out.println("ZIP FILE "+zipFile+"");
    //mm   System.out.println("outputFolder FILE "+outputFolder+"");

        ZipInputStream zis =

        //get the zipped file list entry
        ZipEntry ze = zis.getNextEntry();

        while (ze != null) {

            String fileName = ze.getName();
            File newFile = new File(outputFolder + File.separator + fileName);

            //mm  System.out.println("file unzip : " + newFile.getAbsoluteFile());

            new File(newFile.getParent()).mkdirs();

    } catch (IOException ex) {
