I have set up recyclerview for same Api data on two fragments.After clicking on one of Card, a new Detail fragment for same Card is open on Another Fragment.The cardview contain images.After clicking one of image I need to get information of that CardView position.But as I click on one of card in First Fragment and I move to same card position in Second Fragment but I swipe to other cards and click on Image of other CardView still I am getting information for same Card which was clicked first.
This is code for Adapter

I am getting the same Idno for all CardView after swiping to other cards.How to resolve this ?
pass the model of list in the constructor of the fragment at time of begin transaction and receive it by creating same model in another fragment from constructor

I have a RecyclerView of questions (which are saved and retrieved from database) and seekbars (which I save in database).
Link to image
After clicking on SUBMIT EXTRA QUESTIONS there is a dialog which appears
Link to image
I want after clicking on Okay the progress of ALL seekbars to be 0.
I tried to do this submitExpenseData(jsonArrayQuestion.toString(), getId, jsonArrayAnswer.toString(), formatter.format(date));
holder.seekBar.setProgress(0);
But It changes only the progress of the last seekbar. Does anyone have any idea?

Hi everyone My problem is weird. I have an app that works with volley and mysql. When I launch the app using xampp it works fine. The list is saved in the adapter and adapter works well in the recycler view. But when I change the url to my mysql database hosted on my website, the recycler view does not show the data. The JSON data is correctly received and saved correctly in the Arraylist (check it with Toast messages). I have the same problem in real devices
Android Studio will not throw me any error or warning running

This is the JSON response I am getting after posting the Review
E/final Json: {"studentId":1,"courseId":1,"review":"Hellooooo","ratings":3}

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
I have five tabs they are 1.home 2.menu 3.cart 4.account 5.more.Here cart tab consist of list view which is having the remove button in it,when i click on that remove button it must refresh the fragment itself so that it can load new data from the Json

You need to remove the concerned object from the list cartitems and then call the notifyDataSetChanged() method to notify the any dependent views to refresh itself.
Documentation here
Also, this is not the correct way to implement a BaseAdapter and handle changes in it. Maybe this will help : http://androidadapternotifiydatasetchanged.blogspot.in/
Also, try using the new RecyclerView in order to implement such things. It is available in the support library and definitely a good way to display collections and also makes it easy to add remove items with default animations too. Please read through it. A starting point http://developer.android.com/training/material/lists-cards.html
see added line and updated line.
add make sure only remove item from list if removed successfully from server.
