CustomListViewAdapter

Please help,

I just want to add listview from JSON to fragment but I get an error on this line :

I am trying to scroll programmatically to a certain position within a list view while using a CustomListViewAdapter.

I use a customlistviewadapter because whenever an item within the listview is clicked, it "opens up" to display some text. It is at that point that I want to scroll programmatically to the top of the text just displayed.

At present, it all works fine, EXCEPT that I don't know how to call the function:

i am creating an image downloading app that takes image urls, downloads images and displays them in a listview. For this i am manipulating the xml through program. the question is how i can manipulate an xml file that is not my main xml file through program.

I'm using HashMap to fetch values for my listview adapter. The problem is that the last two elements of my HashMap are repeated. I have tried different solutions before posting this question. Some help would be highly appreciated, Thank you.

Here is the code for my HashMap

I have Navigation drawer -> If I click item from the Navigation drawer, it opens the separate Fragment which has two tabs named as "Lists" and "Photos".

My aim is, when I click the first tab ie. "Lists tab", I am trying to call "Listclassfragment class" which has to display listview. When I click or swipe the second tab ie. photos tab, "photosfragment" class will be called and it has to show photos in grid. I am achieving this by using ViewPagerAdapter.

When I try to work on ListClassFragment, I am getting the Error,

Error : incompatible types: Activity cannot be converted to ListClassFragment

ListClassFragment class:

I have done Google searches and searched stackoverflow. None of the information I have found solves this problem.

I have an ExpandableListView whose children are a RelativeLayout of four LinearLayouts that contain TextViews which will pull answers to a question and assign that question a score from 1-4 (bad, mediocre, good, and world class respectively), and finally an EditText for the user to leave comments on why they rated the question that score. When the user clicks a score box, the background changes colour to highlight the selected score, and sets the other score box colours back to their default colour to show that they are no longer selected. Below is my Java to show how this works:

Apologies in advance if this is a dumb question. I have searched the web for an answer to my issue, but have not found anything that would help.

I have a ListView and a CustomViewAdapter within a Fragment. This works fine. The list is displayed correctly.

What I have a problem with is if a row within the list changes, although the row gets updated, the actual list does not. To put it in context, what I have is a list of favorites and they are shown in a favorites fragment. However, if the user "unfavorites" an item, even though the icon that shows it is a favorite change, the actual list still shows that item, rather than refresh the list and remove that item from the list.

As I said, I have tried all the solutions I could find related to this issue, such as calling notifyDataSetChanged with the adapter.
