如何壓縮和解壓縮包含相同目錄結構的文件

Question

我已經完成了一些實現，當我創建壓縮文件時，一切正常，壓縮文件已創建，並且它還包含所有文件，而不創建目錄結構。這意味着當我解壓文件時，我有看到所有文件沒有目錄結構。請幫我 把它整理出來..

這裏是我wrriten代碼..

      int len = list.length;     
      for(int i = 0; i < len; i++) 
       zip_Folder(new File(file.getPath()+"/"+ list[i]), zipOut); 
     } 
    } 

這裏是解壓的代碼。 ..

您應該將文件夾條目也添加到zip。 也就是說使用目錄名創建ZipEntry（並且不要忘記尾部斜線 - 這對於ZIP歸檔非常重要）。 然後，使用歸檔目錄中的完整相對路徑添加文件條目。
