what i am trying to do here is i am taking 1 edit text where i am putting number to enter , sending centerid,and tabID as parameter and for that i am doing Api Calling using Retrofit. but my problem is that whenever it goes to public void onResponse(Call call, Response response) {
it comes out from there and goes to failure and i am not getting the result after clicking the button.its showing me nothing .

Might be i got the problem.
Problem is here #GET("/v1/android_tutorials/single_advance?") you have? in the end of your url and you also have #Query("advance_id") field that mean your request contain two ?. you request currently look like this.
/v1/android_tutorials/single_advance??advance_id="xxxx"
Remember when you add #Query("advance_id") to your request this by default add ? to your your. So remove? from your url end. Your url should look like this
#GET("/v1/android_tutorials/single_advance")

Try to remove / before v1 in your interface GET method and add that into your base url. In short in any method of retrofit interface don't start with /.

Assuming data is there try making below changes
public class JavaGetAheadAdapter extends RecyclerView.Adapter<JavaGetAheadAdapter.CustomViewHolder> {
List<JavaDatum> GHmdel = new ArrayList(); //new change
Context context;
//removed the list from constructor
public JavaGetAheadAdapter(Context context) {
this.GHmdel = employees;
}
//new method for updating the data items
public void updateData(List<JavaDatum> employees){
this.GHmdel.addAll(employees);
notifyDataSetChanged();
}
#Override
public CustomViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.getaheadnext_item, parent, false);
return new CustomViewHolder(itemView);
}
#Override
public void onBindViewHolder(CustomViewHolder holder, int position) {
holder.employeeName.setText(GHmdel.get(position).getFileName());//
holder.textView.setText(GHmdel.get(position).getCode());
Log.d("adapter",GHmdel.get(position).getFileName());
Log.d("adapter2",GHmdel.get(position).getCode());
}
#Override
public int getItemCount() {
return GHmdel.size();
}
public class CustomViewHolder extends RecyclerView.ViewHolder {
public TextView employeeName;
TextView textView;
public CustomViewHolder(View view) {
super(view);
employeeName = (TextView) view.findViewById(R.id.detailsgetaheadtitle);
textView = view.findViewById(R.id.detailsgetahead);}}}
At the calling side just make the mentioned below changes.
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
/*Create handle for the RetrofitInstance interface*/
progressDialog = new ProgressDialog(getContext());
progressDialog.setMessage("Loading....");
progressDialog.show();
Intent intent = getActivity().getIntent();
String id = intent.getStringExtra("idGHnext");
Log.e("ashwiniiii", String.valueOf(id));

//new changes
adapter.updateData(retro);
Log.e("helloash", String.valueOf(response.body().getJavaData()));
}
#Override
public void onFailure(Call<GetAHeadModelsnext> call, Throwable t) {
progressDialog.dismiss();
Toast.makeText(getContext(), "Something went wrong...Please try later!", Toast.LENGTH_SHORT).show();
}
});
}
//new changes goes here
private void generateDataList(View view) {
recyclerView = view.findViewById(R.id.nextGHrecycle);
LinearLayoutManager manager = new LinearLayoutManager(getContext());
recyclerView.setLayoutManager(manager);
recyclerView.setHasFixedSize(true);
adapter = new JavaGetAheadAdapter(getContext());
recyclerView.setAdapter(adapter);
}}
Try and comment below if its working or not still.

This is the JSON response I am getting after posting the Review
E/final Json: {"studentId":1,"courseId":1,"review":"Hellooooo","ratings":3}
E/Json response: {"success":true,"msg":"Your review has been added successfully","data":{"reviewsId":18}}

private ArrayList<Review> getDataSet(JSONArray array) {

for (int i = 0; i < array.length(); i++) {
try {

Review obj = new Review(object.getInt("studentId"),object.getInt("courseId"),object.getString("Review"),object.getLong("rating"));
results.add(i,obj);
}
catch (Exception e){
e.printStackTrace();
}
}
return results;
}
try to change your getDataSet function with above code and check with debug point if you get any problem in some line. feel free to ask further will help you
EDIT:
You need to change your Pojo class of Review also. Because in JSON response you are not getting userId and reviewId. Hope you understand

Thank you so much for reading. I created a program to search title of the posts. When I type title in the EditText then press Search button, my toast1 test, toast2 test, and toast3 test give correct and same value and it successfully lists what I want with Query. But the problem is that when I type different text in EditText after deleting the previous text then press enter, toast3 test(in FragmentSearch.java) stays the same and does not change value. So, it just gives the previous result, not changed result. Can anyone assist me with this? Thank you!

The problem is that you only change the value on the FragmentSearch constructor. And this constructor is only called once, and not when you press Enter.
You should change your getQuery method to have this value as a parameter.
On your MainFragment.java:
public abstract Query getQuery(DatabaseReference databaseReference, String value);
On your FragmentSearch.java:
#Override
public Query getQuery(DatabaseReference databaseReference, String value)
{
this.value = value;
Toast.makeText(getActivity().this, "value test 3: " + value, Toast.LENGTH_LONG).show();
Query postsQuery = databaseReference.child("Post").orderByChild("title").equalTo(value);
return postsQuery;
}
