在Volley分段请求中显示百分比进度

Question

大家好，我正在使用Volley MultipartRequest将多个图像上传到服务器，我想显示上传到服务器的文件数量以及剩余文件的进度。这是我上传多个图像的方法

public void apiCall2()
{
    String url= BaseUrl.baseUrl+"addcart";
    progressDialog.show();

    final VolleyMultipartRequest multipartRequest = new VolleyMultipartRequest(Request.Method.POST, url, new Response.Listener<NetworkResponse>() {
        @Override
        public void onResponse(NetworkResponse response) {
            String resultResponse = new String(response.data);
            try {
                progressDialog.cancel();
                JSONObject result = new JSONObject(resultResponse);
                Log.i("result",result.toString());
                String status = result.getString("success");
                String message = result.getString("msg");
                if(status.equalsIgnoreCase("true"))
                {
                    Toast.makeText(UploadImageActivity.this,"Images Uploaded Successfully !", Toast.LENGTH_SHORT).show();
                   Intent intent=new Intent(UploadImageActivity.this,CartActivity.class);
                   startActivity(intent);
                }
                else
                    Toast.makeText(UploadImageActivity.this, message, Toast.LENGTH_SHORT).show();

            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            NetworkResponse networkResponse = error.networkResponse;
            String errorMessage = "Unknown error";
            if (networkResponse == null) {
                if (error.getClass().equals(TimeoutError.class)) {
                    errorMessage = "Request timeout";
                } else if (error.getClass().equals(NoConnectionError.class)) {
                    errorMessage = "Failed to connect server";
                }
            } else {
                String result = new String(networkResponse.data);
                try {
                    JSONObject response = new JSONObject(result);
                    String status = response.getString("status");
                    String message = response.getString("message");

                    if (networkResponse.statusCode == 404) {
                        errorMessage = "Resource not found";
                    } else if (networkResponse.statusCode == 401) {
                        errorMessage = message+" Please login again";
                    } else if (networkResponse.statusCode == 400) {
                        errorMessage = message+ " Check your inputs";
                    } else if (networkResponse.statusCode == 500) {
                        errorMessage = message+" Something is getting wrong";
                    }
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
            Log.i("Error", errorMessage);
            error.printStackTrace();

        }
    })
    {
        public Map<String,String> getHeaders() throws AuthFailureError
        {
            Map<String,String> headers=new HashMap<String,String>();
            SharedPreferences prefs=getSharedPreferences("token", Context.MODE_PRIVATE);
            String token=prefs.getString("value","wer");
            headers.put("Content-Type", "multipart/form-data; boundary="+VolleyMultipartRequest.boundary);
            headers.put("X-Requested-With","XMLHttpRequest");
            headers.put("Authorization","Bearer "+token);
            return headers;
        }
        @Override
        protected Map<String, String> getParams() {

            Map<String, String> params = new HashMap<>();
            params.put("type",typeId);
            params.put("size",sizeId);
            params.put("manual_image","0");
            if(coverId!=null)
            {
                params.put("cover",coverId);
            }

            return params;
        }

        @Override
        protected Map<String, DataPart> getByteData() {
            Map<String, DataPart> params = new HashMap<>();
            for (int i = 0; i < path.size(); i++) {

                Uri uri= path.get(i);
                String filename=getFileName(uri);
                Log.i("fff",filename);

                try {

                    params.put("photos[" + i + "]", new DataPart(filename, data[i], "image/*"));
                    Log.i("filess",data[i].toString());
                    Log.i("cc",String.valueOf(count));

                } catch (Exception e) {
                    e.printStackTrace();
                }


            }



            return params;
        }
    };



    multipartRequest.setRetryPolicy(new DefaultRetryPolicy(
            3000,
            0,
            DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

    VolleySingleton.getInstance(this).addToRequestQueue(multipartRequest);
}

最后，我想显示进度条或进度对话框，例如 正在上传图片（1/20），并且在上传一张图片（2/20）等之后，请有人帮助。我搜索了很多但没有发现
