Upload a file along with other string parameters in android

I have to upload a file and has three more parameters which is string.The file can be image or zip.How is it possible with volley to upload a file and submit string parameters along with it when button is clicked?
I have also tried this link-https://www.simplifiedcoding.net/upload-pdf-file-server-android/
Please help me.Thanks!!
My code is:

private int PICK_PDF_REQUEST = 1;
TextView filetext;
//storage permission code
private static final int STORAGE_PERMISSION_CODE = 123;
String uploadId;
//Uri to store the image uri
private Uri filePath;
Spinner spinner,spinner2;
public Tab1Fragment() {
// Required empty public constructor
}
public static Tab1Fragment newInstance() {
Tab1Fragment fragment = new Tab1Fragment();
return fragment;
}

How to wait for an activity to finish in asynctask

I know that the purpose of the AsyncTask is to run asynchronously with other tasks of the app and finish in the background, but apparently I need to do this, I need to start an activity from AsyncTask and since I cant extend an activity in this class I can not use startactivityforresult, so how can I wait till my activity finishes?
Here is my code:

List ImageView repeating same image when shared

I have a listView that is supposed to accept a shared message and image where the image is placed within the ImageView. This feature works for just the first message, but once an image is shared, each message received after that initial one becomes a copy of that same image even though the blank image placeholder was already set, which is just a one pixel black png:
holder.sharedSpecial.setImageResource(R.drawable.image_share_empty_holder);
An example is below:
The green textbox is the recipient. They have recieved a shared image from the yellow textbox. The yellow textbox then simply sends a normal message and I have set another image as a placeholder for normal messages: holder.sharedSpecial.setImageResource(R.drawable.image_share_empty_holder);
The same previously shared image takes precedence. I have used notifyDataSetChanged() so as to allow for the updating the adapter so that it would recognize not to use the same image, but to no avail.
How can I reformulate this class so that the image shared is only displayed with the proper message and not copied into each subsequent message?

I have gone through your code and this is common problem with listview that images starts repeating itself. In your case I think you have assigned image to Imageview every if and else if condition but if none of the condition satisfy it uses the previous image.
I would suggest to debug the getview method and put break points on the setImageResource. I use volley for these image loading and it has a method called defaultImage so that if no url is there the image is going to get the default one. So add that default case and see if it works.
If any of the above point is not clear feel free to comment.

Android TextView doesn't update

I am developing an Android app. Please see the Java code below. Can you please explain why textView doesn't update at specific lines in code but updates at others. I have them commented in the code.
I have updated the code see below.
The idea is to get a facebook profile from a server. When profiling_status equals 2 means that the profile is not ready, so I'll just ping the server until I get profiling_status != 2..
I tried the progress dialog thingy but gave up cause I put my activity in a thread, but then I couldn't get some information because I should have run it in nonUIThread.. Tried that but I failed and I lost patience.. so decided that while I ping the server I should just print "Loading profile. Please wait." No mess, no fuss! Only as said, textView doesn't update. Interestingly enough.. System.out.println("Here"); gets executed. I am running it only on AVD at the moment cause the server is not on the wireless network so I can't use a mobile phone to test it.

I thing your username is a string . Normally it will be so use !username.equals() dont use != in string comparison. that code may not get executed

if (username != null || !username.equals("")) {
//to do
}

Try out as below to compare the string do not use == use equalsIgnoreCase() or equals() method.
if (profiling_status.equalsIgnoreCase("2")) {
//would not update here either
try {
while (profiling_status.equalsIgnoreCase("2") && time < 100000) {
textView.setText("Loading profile. Please wait.");
try {
Thread.sleep(time_interval);
time += time_interval;

The problem is that when I click login button for the first time, everything works fine, but when I click it the second time, the testUserMethod, try{ statement is ignored.. Found the problem - again, my own mistake, everything is ok now. Thank you everybody who helped

Can you check with setCancelable().. you are setting it to true once and again to false...

It looks like problem isn't here. Maybe, you did some field static?
