所以我創建了一個類,在這裏找到了這些例子。 http://www.jondev.net/articles/Zipping_Files_with_Android_%28Programmatically%29這是偉大的,它創造奇蹟,文件。說到文件夾,它不起作用。我嘗試將字符串切換到文件並使用isDirectory,但這是不行的。這裏是代碼:在android中對文件和文件夾進行壓縮

import android.util.Log; 
import java.io.BufferedInputStream; 
import java.io.BufferedOutputStream; 
import java.io.FileInputStream; 
import java.io.FileOutputStream; 
import java.util.zip.ZipEntry; 
import java.util.zip.ZipOutputStream; 

public class Compress { 

    private static final int BUFFER = 2048; 
    private String[] _files; 
    private String _zipFile; 

    public Compress(String[] files, String zipFile) { 
     _files = files; 
     _zipFile = zipFile; 
    } 

    public void zip() { 
     try { 
      BufferedInputStream origin = null; 
      FileOutputStream dest = new FileOutputStream(_zipFile); 
      ZipOutputStream out = new ZipOutputStream(new BufferedOutputStream(
        dest)); 
      byte data[] = new byte[BUFFER]; 
      for (int i = 0; i < _files.length; i++) { 
       Log.v("Compress", "Adding: " + _files[i]); 
       FileInputStream fi = new FileInputStream(_files[i]); 
       origin = new BufferedInputStream(fi, BUFFER); 
       ZipEntry entry = new ZipEntry(_files[i].substring(_files[i] 
         .lastIndexOf("/") + 1)); 
       out.putNextEntry(entry); 
       int count; 
       while ((count = origin.read(data, 0, BUFFER)) != -1) { 
        out.write(data, 0, count); 
       } 
       origin.close(); 
      } 
      out.close(); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 
}

如果你設法使它壓縮文件夾也請聯繫我,我有同樣的問題,並沒有管理尚未 –

看起來像它不支持添加目錄與內容。 因此,您應該手動瀏覽目錄結構並添加目錄和子目錄中的所有文件。
