I used PagerAdapter for sliding images and i added a favorite button too in that sliding image. After clicking favorite button its not getting notified properly image not turns to unfavorite icon.
it is for loading api

As far as i am able to understand your question you want favorite and unfavorite functionality by adapter . Please use this code below to achieve that :

How to do Filter listview in android?

How to do the Filter concept from Below design? I here by attached two screen designs.
DashBoard Fragment -> Having Listview with Base adapter.
The above ListView code is given Below
DashBoardRefactor
public class DashBoardRefactor extends Fragment {
public static ProgressDialog progress;
public static List<DashListModel> dashRowList1 = new ArrayList<DashListModel>();
public static View footerView;
// #Bind(R.id.dashListView)
public static ListView dashListView;
int preCount = 2, scroll_Inc = 10, lastCount;
boolean flag = true;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

ButterKnife.bind(this, v);

Clarification:
How do to Filter while click the Filter Button On DashBoard Fragment. Please Suggest the way. I here by attached My Filter design also.
Dashboard Fragment--> Filter Button-> Filter screen-> the Filtered results should view on DashBoard Fragment.
Once click the apply Button Based on the input from Filter screen it filters the list view the result comes from back end team. I have to display that result on Dashboard Fragment.
Kindly please clarify this Filter concept.

What do you want? You want to scroll List after update List it reached at Top not at same List State? Is it Right?
Please Check this
private void scrollMyListViewToBottom() {
myListView.post(new Runnable() {
#Override
public void run() {
// Select the last row so it will scroll into view...
myListView.setSelection(myListAdapter.getCount() - 1);
}
});
}
check this Please.

AsynTask with Endless Listview Scroll in android

I am creating an application where in i need to have endless scrolling listview. I dnt want to use any library in my application. I have seen some examples on line that help in achieving such listview,but my doubt is how can i have an endless listview when my data are coming from server and are getting parsed in the Asynctask. How can i load 10 items at a time from my asynctask on scroll? I want to know to implement a endless listview on asyntask.
Do i call my asynctask in the onScroll() or not???

Thanks in advance.

ListView already supports OnScrollListener, so you have to override it and check the condition(in onScroll()), whether it is reached to the end of the list or not.If yes, then add a footer(optional) and fire the async task. After reciving the result notify the adapter. You could check solution on this link, it works on the same concept.

here are few examples of what you are looking for:

I think the problem is you aren't calling the super class of notifyDataSetChanged(), maybe try
#Override
public void notifyDataSetChanged() {
rows.clear();
for (HashMap<String, String> addvert : data) {
rows.add(new MyAddActivateRow((LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE), addvert));
Log.d("MyActivateAdapter", "update " + data.size());
}
super.notifyDataSetChanged();
}
