Android 解压zip文件

这两天研究了一下android下的解压所技术，略有所获，下面是解压缩的操作方法。

	private void unZipMapCache(){
		 try {
		        
				InputStream is = this.getAssets().open(ASSETS_NAME);
				ZipInputStream zis= new ZipInputStream(is);
				ZipEntry entry = null;
				while((entry = zis.getNextEntry()) != null){
					File file = new File("/mnt/sdcard/",entry.getName());
					if(entry.isDirectory()){
						file.mkdirs();
						continue;
					}else{
						file.createNewFile();
						  OutputStream myOutput = new FileOutputStream(file);
						  byte[] buffer = new byte[1024];
					         int count;
					         while ((count = zis.read(buffer)) != -1) {
					        	 myOutput.write(buffer, 0, count);
					         }
					         myOutput.close();
					}
				}
				zis.close();
				is.close();
				
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
	}
