android如何解压zip文件，将目录结构也一起解压出来

如何将一个zip文件原本的目录结构完整的解压出来呢，我用的这个解压方法目前只能把文件解压出来，原本的目录结构没了

/**
     * 解压Zip文件
     * @param srcPath zip文件路径
     * @param targePath 解压路径
     * @throws IOException
     */
    public static void unZipFile(String srcPath, String targePath) throws IOException {
        BufferedInputStream bi;
        ZipFile zf = new ZipFile(srcPath);
        Enumeration e = zf.entries();
        while (e.hasMoreElements()) {
            ZipEntry ze2 = (ZipEntry) e.nextElement();
            String entryName = ze2.getName();
            String path = targePath + "/" + entryName;
            if (ze2.isDirectory()) {
                Log.d(TAG,"正在创建解压目录 - " + entryName);
                File decompressDirFile = new File(path);
                if (!decompressDirFile.exists()) {
                    decompressDirFile.mkdirs();
                }
            } else {
                Log.d(TAG,"正在创建解压文件 - " + entryName);
                String fileDir = path.substring(0, path.lastIndexOf("/"));
                File fileDirFile = new File(fileDir);
                if (!fileDirFile.exists()) {
                    fileDirFile.mkdirs();
                }
                BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(targePath + "/" + entryName));
                bi = new BufferedInputStream(zf.getInputStream(ze2));
                byte[] readContent = new byte[1024];
                int readCount = bi.read(readContent);
                while (readCount != -1) {
                    bos.write(readContent, 0, readCount);
                    readCount = bi.read(readContent);
                }
                bos.close();
            }
        }
        zf.close();
    }

zip文件的entry可以判定是目录还是文件的啊，根据这个就可以做到解压时与zip文件里的目录树保持一致
