Question

我做了某种实现，当我创建zip文件时一切都很好，创建了zip文件，它还包含所有文件而不创建目录结构。这意味着当我解压缩文件时，我看到所有没有目录结构的文件。请帮忙我要解决它..

这是我编写的代码..

public void createZipFolder(String path) 
{   

    File dir = new File(path);
    String list[] = dir.list();
    String name = path.substring(path.lastIndexOf("/"), path.length());
    String n = path.substring(path.indexOf("/"), path.lastIndexOf("/"));
    Log.d("JWP", "New Path :"+n);

    String newPath;
    if(!dir.canRead() || !dir.canWrite()){
        return;
    }
    int len = list.length;

    if(path.charAt(path.length() - 1) != '/'){
        newPath = n + "/";
    }
    else{
        newPath = n;
    }
    try{
        ZipOutputStream zipOut = new ZipOutputStream(new BufferedOutputStream(new FileOutputStream(newPath + name + ".zip"),BUFFER));
        for(int i = 0; i < len; i++){
            zip_Folder(new File(path +"/"+ list[i]),zipOut);
        }
        zipOut.close();
    }
    catch(FileNotFoundException e){
        Log.e("File Not Found", e.getMessage());
    }
    catch(IOException e){
        Log.e("IOException", e.getMessage());
    }       
}



private void zip_Folder(File file, ZipOutputStream zipOut)throws IOException {
    // TODO Auto-generated method stub
    String s1 = file.getPath();
    Log.d("JWP", "PATH "+s1);
    byte data[] = new byte[BUFFER];
    int read;
    if(file.isFile()){
        ZipEntry entry = new ZipEntry(file.getName());
        zipOut.putNextEntry(entry);
        BufferedInputStream inputStream = new BufferedInputStream(new FileInputStream(file));
        while((read = inputStream.read(data,0,BUFFER)) != -1){
            zipOut.write(data, 0, read);
        }
        zipOut.closeEntry();
        inputStream.close();
    }
    else if(file.isDirectory()){                
            String[] list = file.list();
            int len = list.length;                  
            for(int i = 0; i < len; i++)
                zip_Folder(new File(file.getPath()+"/"+ list[i]), zipOut);
        }
    }

这是Unzip的代码......

public void extractZipFiles(String zipFile, String dir){
    Log.d("JWP", "ZIP FILE :"+zipFile+ " DIR :"+dir);
    byte data[] = new byte[BUFFER];
    String name,path,zipDir;
    ZipEntry entry;
    ZipInputStream zipInputStream;
    if(!(dir.charAt(dir.length() - 1) == '/' )){
        dir += "/";
    }
    if(zipFile.contains("/")){
        path = zipFile;
        name = path.substring(path.lastIndexOf("/") + 1, path.length() - 4);

        zipDir = dir + name + "/";
    }
    else{
        path = dir + zipFile;
        name = path.substring(path.lastIndexOf("/") + 1, path.length() - 4);
        zipDir = dir + name + "/";
    }
    new File(zipDir).mkdir();
    try{
        zipInputStream = new ZipInputStream(new FileInputStream(path));
        while((entry = zipInputStream.getNextEntry()) != null){
            String buildDir = zipDir;
            String dirs[] = entry.getName().split("/");
            if(dirs != null && dirs.length > 0){
                for(int i = 0; i < dirs.length - 1; i++){
                    buildDir += dirs[i] + "/";
                    new File(buildDir).mkdir();
                }
            }
            int read = 0;
            FileOutputStream out = new FileOutputStream(zipDir + entry.getName());
            while((read = zipInputStream.read(data, 0, BUFFER)) != -1){
                out.write(data, 0, read);
            }
            zipInputStream.closeEntry();
            out.close();
        }
    }
    catch(FileNotFoundException e){
        e.printStackTrace();
    }
    catch(IOException e){
        e.printStackTrace();
    }
}

您还应该将文件夹条目添加到zip。即创建具有目录名称的ZipEntry（并且不要忘记尾部斜杠 - 它对于ZIP存档很重要）。并且，使用您要归档的目录中的完整相对路径添加文件条目。
