Android中用Java代码实现zip文件解压缩如果需要下载的文件有很多是中文名的，解压时有中文名的文件出现乱码，试了很多方法不能解决问题。据说有一个Java插件包，用这个插件包可以解决中文名乱码的问题，但不知解压的文件是否要用它提供的类压缩后的文件，是否能解决用rar工具压缩的有中文名的文件，这个还没有试过。参考资料：@1.http://www.oschina.net/code/snippet_4873_4142 阅读详情

1、文件解压缩

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;   
   
/**

 * @author jon  
 */   
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();   
    }   
  }   
}

2、文件压缩

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();   
    }   
   
  }   
   
}
