将文件保存到特定文件夹并转换为zip文件

Question

我必须上传文件并转换为zip文件并保存到服务器。

但在上传到服务器之前，文件应该包装在一个文件夹中然后应该转换为zip文件。

在下面的代码中，我可以直接转换为zip文件而不将其包装在文件夹中。

我使用 M-zip 库转换为zip文件。

在上传到服务器之前，能帮我将文件上传到文件夹中吗？

public void uploadMultipart() {
    //getting name for the image
    String subject = subj.getText().toString().trim();
    String description = desx.getText().toString().trim();
    String depart = spinner.getSelectedItem().toString();
    String prior = spinner2.getSelectedItem().toString();
    //getting the actual path of the image

    String path = FilePath.getPath(getActivity(), filePath);

    String filename = path.toString();
    String zipPath=null;

        // Do something on success

        String fname = filename.substring(0, filename.lastIndexOf("."));
        zipPath = fname+".zip";
        Log.d("FileNameZip",zipPath);


        ZipArchive zipArchive = new ZipArchive();
        zipArchive.zip(path, zipPath, "");


    String p = null;
    int cut = filename.lastIndexOf('/');
    p = filename.substring(0,cut+1);
    if (cut != -1) {
        Log.d("FileNameCut",String.valueOf(cut));
        filename = filename.substring(cut + 1);
        Log.d("FileName " , p);
        Log.d("FileName " , p+filename);

    }
