推荐答案

这一块code可以帮助你....只是擦肩而过，你要提取的文件保存到这个zip文件，并将该位置一流的同时使一个对象......并调用解压方法...

This piece of code will help you....Just pass the zipfile location and the location where you want the extracted files to be saved to this class while making an object...and call unzip method...

    public class Decompress { 
  private String zip; 
  private String loc; 

  public Decompress(String zipFile, String location) { 
    zip = zipFile; 
    loc = location; 

    dirChecker(""); 
  } 

  public void unzip() { 
    try  { 
      FileInputStream fin = new FileInputStream(zip); 
      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(loc + 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(); 
    } 
  } 
}
