how to convert code of an activity to fragment - android-fragments

Question

I am converting my activity unto a fragment, then I received an error which I think I just need to add some code, what should I add
private class AsyncLogin extends AsyncTask<String, String, String> {
ProgressDialog pdLoading = new ProgressDialog(NotifMainActivity.this);
HttpURLConnection conn;
URL url = null;
errors are from the "NotifMainActivity.this" it says "in progress dialog cannot be applied" I have included an image for you to see the error in actual.Click here to see the image
Update. So I have change the "NotifMainActivity.this" with getActivity as suggested by sir Kashif Anwar but doing so made the function of the fragment to not work maybe you can provide me an alternative solution.
Here is the whole code of the fragment(this fragment is the activity of a recyclerview)
package com.capstone.jmilibraryapp;
import android.app.ProgressDialog;
import android.os.AsyncTask;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;

import android.widget.Toast;

public class NotifMainActivity extends Fragment {
// CONNECTION_TIMEOUT and READ_TIMEOUT are in milliseconds
public static final int CONNECTION_TIMEOUT = 10000;

private RecyclerView mRVFishPrice;
private AdapterNotif mAdapter;
/*#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notifmainactivity);
//Make call to AsyncTask
new AsyncLogin().execute();
}*/
View myView;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
myView = inflater.inflate(R.layout.activity_notifmainactivity, container, false);
return myView;
}
private class AsyncLogin extends AsyncTask<String, String, String> {
ProgressDialog pdLoading = new ProgressDialog(getActivity());
HttpURLConnection conn;
URL url = null;
#Override

super.onPreExecute();
//this method will be running on UI thread
pdLoading.setMessage("\tLoading...");
pdLoading.setCancelable(false);
pdLoading.show();
}
#Override

try {
// Enter URL address where your json file resides
// Even you can make call to php file which returns json data
url = new URL("http://192.168.1.101/notif.php");
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return e.toString();
}
try {
// Setup HttpURLConnection class to send and receive data from php and mysql
conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(READ_TIMEOUT);

// setDoOutput to true as we recieve data from json file
conn.setDoOutput(true);
} catch (IOException e1) {
// TODO Auto-generated catch block

return e1.toString();
}
try {
int response_code = conn.getResponseCode();
// Check if successful connection made
if (response_code == HttpURLConnection.HTTP_OK) {
// Read data sent from server
InputStream input = conn.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(input));
StringBuilder result = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
result.append(line);
}
// Pass data to onPostExecute method
return (result.toString());
} else {
return ("unsuccessful");
}
} catch (IOException e) {
e.printStackTrace();
return e.toString();
} finally {
conn.disconnect();
}
}
#Override
protected void onPostExecute(String result) {
//this method will be running on UI thread
pdLoading.dismiss();
List<DataNotif> data=new ArrayList<>();
pdLoading.dismiss();
try {
JSONArray jArray = new JSONArray(result);
// Extract data from json and store into ArrayList as class objects
for(int i=0;i<jArray.length();i++){
JSONObject json_data = jArray.getJSONObject(i);
DataNotif fishData = new DataNotif();
fishData.NotifTitle= json_data.getString("notif_Title");
fishData.NotifMessage= json_data.getString("notif_Message");
// fishData.sizeName= json_data.getString("size_name");
fishData.Date= json_data.getString("notif_date");
data.add(fishData);
}
// Setup and Handover data to recyclerview
mRVFishPrice = (RecyclerView)myView.findViewById(R.id.fishPriceList);
mAdapter = new AdapterNotif(getActivity(), data);
mRVFishPrice.setAdapter(mAdapter);
mRVFishPrice.setLayoutManager(new LinearLayoutManager(getActivity()));
} catch (JSONException e) {
Toast.makeText(getActivity(), e.toString(), Toast.LENGTH_LONG).show();
Toast.makeText(getActivity(), "There maybe some error try again",Toast.LENGTH_LONG).show();
}
}
}
}

Answer 1

You should use getActivity() instead of class name,
like this
ProgressDialog pd = new ProgressDialog( getActivity() );
Hope it helps!
