Extract کردن یک فایل zip

از این کلاس میتونید استفاده کنید :

import android.util.Log; 

import java.io.File; 

import java.io.FileInputStream; 

import java.io.FileOutputStream; 

import java.util.zip.ZipEntry; 

import java.util.zip.ZipInputStream; 



public class Decompress { 

  private String _zipFile; 

  private String _location; 

 

  public Decompress(String zipFile, String location) { 

    _zipFile = zipFile; 

    _location = location; 

 

    _dirChecker(""); 

  } 

 

  public void unzip() { 

    try  { 

      FileInputStream fin = new FileInputStream(_zipFile); 

      ZipInputStream zin = new ZipInputStream(fin); 

      ZipEntry ze = null; 

      while ((ze = zin.getNextEntry()) != null) { 

        Log.v("Decompress", "Unzipping " + ze.getName()); 

 

        if(ze.isDirectory()) { 

          _dirChecker(ze.getName()); 

        } else { 

          FileOutputStream fout = new FileOutputStream(_location + ze.getName()); 

          for (int c = zin.read(); c != -1; c = zin.read()) { 

            fout.write(c); 

          } 

 

          zin.closeEntry(); 

          fout.close(); 

        } 

         

      } 

      zin.close(); 

    } catch(Exception e) { 

      Log.e("Decompress", "unzip", e); 

    } 

 

  } 

 

  private void _dirChecker(String dir) { 

    File f = new File(_location + dir); 

 

    if(!f.isDirectory()) { 

      f.mkdirs(); 

    } 

  } 

}

به این صورت استفاده میشه :

String zipFile = Environment.getExternalStorageDirectory() + "/files.zip"; 

String unzipLocation = Environment.getExternalStorageDirectory() + "/unzipped/"; 

 

Decompress d = new Decompress(zipFile, unzipLocation); 

d.unzip();
