封装了一个类，类的代码如下

public class Decompress {//String zipFilePath = "/sdcard/archive.zip";//String destinationPath = "/sdcard/extracted_files";//ZipUtils.unzip(zipFilePath, destinationPath);public static void unzip(String zipFilePath, String destinationPath) {try {File destinationFolder = new File(destinationPath);if (!destinationFolder.exists()) {destinationFolder.mkdirs();}FileInputStream fileInputStream = new FileInputStream(zipFilePath);ZipInputStream zipInputStream = new ZipInputStream(fileInputStream);ZipEntry zipEntry = zipInputStream.getNextEntry();byte[] buffer = new byte[1024];while (zipEntry != null) {String entryName = zipEntry.getName();File file = new File(destinationPath + File.separator + entryName);if (zipEntry.isDirectory()) {file.mkdirs();} else {FileOutputStream fileOutputStream = new FileOutputStream(file);int length;while ((length = zipInputStream.read(buffer)) > 0) {fileOutputStream.write(buffer, 0, length);}fileOutputStream.close();}zipEntry = zipInputStream.getNextEntry();}zipInputStream.closeEntry();zipInputStream.close();fileInputStream.close();LogUtils.log("解压缩完成！");} catch (Exception e) {e.printStackTrace();}}
}  

参数 zipFilePath 是zip压缩包的路径

参数 destinationPath 是解压缩的目标目录。

静态方法直接调用即可，可以在Android上使用
