[移动开发]Android文件解压【已测通】

废话不多说，直接上代码：

/**
     * 文件解压
     * @param zipFileString 压缩文件路径
     * @param folderPath 解压输出路径
     * @throws IOException
     */
    public static void UnZipFolder(String zipFileString, String folderPath) throws IOException {
        ZipFile zfile = new ZipFile(new File(zipFileString));
        Enumeration zList = zfile.entries();
        ZipEntry ze = null;
        byte[] buf = new byte[1024];
        while (zList.hasMoreElements()) {
            ze = (ZipEntry) zList.nextElement();
            if (ze.isDirectory()) {
                Log.d(TAG, "ze.getName() = " + ze.getName());
                String dirstr = folderPath + ze.getName();
                dirstr = new String(dirstr.getBytes(StandardCharsets.UTF_8), StandardCharsets.UTF_8);
                Log.d(TAG, "str = " + dirstr);
                File f = new File(dirstr);
                f.mkdir();
                continue;
            }
            Log.d(TAG, "ze.getName() = " + ze.getName());
            OutputStream os = new BufferedOutputStream(new FileOutputStream(getRealFileName(folderPath, ze.getName())));
            InputStream is = new BufferedInputStream(zfile.getInputStream(ze));
            int readLen = 0;
            while ((readLen = is.read(buf, 0, 1024)) != -1) {
                os.write(buf, 0, readLen);
            }
            is.close();
            os.close();
        }
        zfile.close();
    }
