如何在android中遞歸的Zip文件夾？

Question

我能夠壓縮文件夾，但不是遞歸的方式。請給我一個解決方案？

Answer 1

作爲在Java（它是相同的）

static public void zipFolder(String srcFolder, String destZipFile) 
     throws Exception { 
    ZipOutputStream zip = null; 
    FileOutputStream fileWriter = null; 
    fileWriter = new FileOutputStream(destZipFile); 
    zip = new ZipOutputStream(fileWriter); 
    addFolderToZip("", srcFolder, zip); 
    zip.flush(); 
    zip.close(); 
} 

static private void addFileToZip(String path, String srcFile, 
     ZipOutputStream zip) throws Exception { 
    File folder = new File(srcFile); 
    if (folder.isDirectory()) { 
     addFolderToZip(path, srcFile, zip); 
    } else { 
     byte[] buf = new byte[1024]; 
     int len; 
     FileInputStream in = new FileInputStream(srcFile); 
     zip.putNextEntry(new ZipEntry(path + "/" + folder.getName())); 
     while ((len = in.read(buf)) > 0) { 
      zip.write(buf, 0, len); 
     } 
    } 
} 

static private void addFolderToZip(String path, String srcFolder, 
     ZipOutputStream zip) throws Exception { 
    File folder = new File(srcFolder); 
    for (String fileName : folder.list()) { 
     if (path.equals("")) { 
      addFileToZip(folder.getName(), srcFolder + "/" + fileName, zip); 
     } else { 
      addFileToZip(path + "/" + folder.getName(), srcFolder + "/" 
       + fileName, zip); 
     } 
    } 
} 

這裏第一種方法（zipFolder）是主要的方法，其它的兩個簡單地壓縮的單個文件（addFileToZip）或文件夾（addFolderToZip）。
