Your code is almost fine. You just missed one thing. You did not initialize VolleyRequest. Inside simponData and UpdateData methods write this line at the bottom.
RequestQueue requestQueue = Volley.newRequestQueue(getContext());
requestQueue.add(my_request);
instead of AppController.getInstance().addToRequestQueue(updateReq).
other thing is you are calling the fragment in intent from when response is received .You should call onbackPress() when result is recieved successfully.
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
pd.cancel();
try {
JSONObject res = new JSONObject(response);
Toast.makeText(InsertKategori.this, ""+ res.getString("message") , Toast.LENGTH_SHORT).show();
} catch (JSONException e) {
e.printStackTrace();
}
onBackPressed();
}
},
It will restore the previous fragment. In order to update the KategoriFragment view when successful response is received, you can call the getData() method in onResume() method instead of oncreate(). it will call this method whenever fragment is visible to the use
This is my code for getting the data from JSON, it will contain only one row,
but it will give output for only "pro_name" for left of the values it will give just dots(......).

Sorry I made the Mistake that in TextView I put the text as password .
I'm trying to build a simple phonebook application where I can perform a search and an API will return the information. So far this is the part that I've got working.
I also want incoming caller to be identified with the same API, that would require the incoming number from Broastcastreceiver to be put into the API query and the returned information should be displayed in a toast. This is the part I'm having problems with.
So far this is what I have. Apologize if its really messy, this is what I've been playing around with recently and made small adjustments. Also its alot of copy-paste, I'm a beginner at java/Android and trying to learn.

Arent you missing a constructor in your BackgroundTask?
Try putting System.out.println(arrayList.size()) before you return it in your BackgroundTask. What is the size of it?
