RecyleView showing all items duplicates

I am trying to display posts from a server in listView. So I used recycle-view to achieve that. Everything is working fine except that ll items are displaying twice.
I counted the total fetched items from server, and the count is 5, but adapter.getItemCount is showing 10.
After searching hours on the internet, I tried following :
#Override
public long getItemId(int position) {
return position;
}
#Override
public int getItemViewType(int position) {
return position;
}
and
homeFragmentAdapter.setHasStableIds(true);
Below is my fragment...

After trying everything, I was still not able to resolve the issue. Any help/suggestions are welcome. Let me know If I left out any needed code--if so I can update it here.

`postListGlobal.add(postList);` below this line add ` homeFragmentAdapter.notifyDataSetChanged();` and remove ` homeFragmentAdapter.removeNull(); homeFragmentAdapter.addData(postListGlobal);homeFragmentAdapter.notifyDataSetChanged();` this code.Because in this case list added twice without notifying datasetchange check with your code by removing this.

postListGlobal.clear(); just clear tha arraylist before add .

postListGlobal.clear() before adding new list to the adapter.
And then notifyDataSetChanged() to let adapter know of the changes.

Recylerview items that are visible are not getting updated when notifyDataSetChanged() is called

I am having a recycler view whose vies of the items that are visible are not getting updated, when notifyDataSetChanged() is called. The items that are invisible are getting updated without any problem.
I have seen that this has been a problem with listview as given here:
List view not refreshing already visible items
But I am not knowing what to do with recycler view.
In my recycler view adapter I add views dynamically according to my code.

You are adjusting the UI in the background.
Use the method onPostExecute() from AsyncTask to adjust your UI.

In this code, you are not invoking notifyDataSetChanged() when adding items to mBusArrivalPOJOList (for example, check getDataFromJson() for GetNearbyStops class) or I am not able to find where you are invoking it. Please make sure that you are invoking notifyDataSetChanged() immediately after changing the objects you send to adapter be it adding (one item, multiple items) or removing (one item or multiple items) or clearing.

How to do Filter listview in android?

How to do the Filter concept from Below design? I here by attached two screen designs.

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.

Not getting the correct data on clicking the LISTVIEW

I have 3 list in my fragment i.e. list 1,list2 and list3. And all are interdependent.I'm using AsyncTask for showing these list.
When i click on list 1 its shows some data on list 3 and so on when i clik on list 2 it shows data on list3.
Now the problem is there is a next button,if i don't click on list 2 and press next it does not show the correct data.
list 2 returns null and thus does not functional correct.
Below is the code
public class Browse extends Fragment {
ActionBar actionBar;
ListView listView1, listView2, listView3;
