Android解压中文乱码

在Android中内置有解压的工具，一般可以使用下面的方法解压：

注意import的包：

因

import java.util.zip.ZipEntry;import java.util.zip.ZipFile;/**     * 解压缩一个文件     *     * @param zipFile 压缩文件     * @param folderPath 解压缩的目标目录     * @throws IOException 当解压缩过程出错时抛出     */    public static void upZipFile(File zipFile, String folderPath) throws ZipException, IOException {        File desDir = new File(folderPath);        if (!desDir.exists()) {            desDir.mkdirs();        }        ZipFile zf = new ZipFile(zipFile);        for (Enumeration<?> entries = zf.entries(); entries.hasMoreElements();) {            ZipEntry entry = ((ZipEntry)entries.nextElement());            InputStream in = zf.getInputStream(entry);            if(entry.getName().indexOf("__MACOSX")>=0){                continue;            }            String str = folderPath + File.separator + entry.getName();            str = new String(str.getBytes("8859_1"), "UTF-8");            File desFile = new File(str);            if (!desFile.exists()) {                File fileParentDir = desFile.getParentFile();                if (!fileParentDir.exists()) {                    fileParentDir.mkdirs();                }                desFile.createNewFile();            }            OutputStream out = new FileOutputStream(desFile);            byte buffer[] = new byte[BUFF_SIZE];            int realLength;            while ((realLength = in.read(buffer)) > 0) {                out.write(buffer, 0, realLength);            }            in.close();            out.close();        }    }

但是在解压遇到中文的时候，解压出来中文会变成乱码，把上面的编码改成啥都没用。

果

这时候可以使用apache-ant-zip的解压包来解决：

• 先将apache-ant-zip.jar加入依赖，下载地址：http://download.csdn.net/detail/qq_25806863/9878967

然后使用这个包中的引用：

import org.apache.tools.zip.ZipEntry;import org.apache.tools.zip.ZipFile;public static void upZipFile(File zipFile, String folderPath) throws IOException {        OutputStream os = null;        InputStream is = null;        ZipFile zf = null;        try {            zf = new ZipFile(zipFile,"UTF-8");            String directoryPath = "";            directoryPath = folderPath;            Enumeration entryEnum = zf.getEntries();            if (null != entryEnum) {                ZipEntry zipEntry = null;                while (entryEnum.hasMoreElements()) {                    zipEntry = (ZipEntry) entryEnum.nextElement();                    if (zipEntry.isDirectory()) {                       //不处理文件夹                        directoryPath = directoryPath + File.separator                                + zipEntry.getName();                        System.out.println(directoryPath);                        continue;                    }                    if (zipEntry.getSize() > 0) {                        File targetFile = new File(directoryPath+ File.separator + zipEntry.getName());                        if (!targetFile.exists()) {                            //如果不存在就创建                            File fileParentDir = targetFile.getParentFile();                            if (!fileParentDir.exists()) {                                fileParentDir.mkdirs();                            }                            targetFile.createNewFile();                        }                        os = new BufferedOutputStream(new FileOutputStream(targetFile));                        is = zf.getInputStream(zipEntry);                        byte[] buffer = new byte[4096];                        int readLen = 0;                        while ((readLen = is.read(buffer, 0, 1024)) >= 0) {                            os.write(buffer, 0, readLen);                        }                        os.flush();                        os.close();                    }                }            }        } catch (IOException ex) {            throw ex;        } finally {            if (null != is) {                is.close();            }            if (null != os) {                os.close();            }        }    }
