Android searchView not searching the list until fully scrolled

I have a listview with a custom adapter, and Im trying to use SearchView with a CustomFilter. But the search is not "fully" working.
When I search for something that is on the viewable area of the listview, it is able to search, and all nonviewable area is not being included in the search.
Here is a video on whats going on:

main
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_board_game_list, container, false);
this.listView = (ListView) view.findViewById(R.id.listView);
DatabaseAccess databaseAccess = DatabaseAccess.getInstance(this.getContext());
databaseAccess.open();
List<String> boardgamesNames = databaseAccess.getNames();
List<String> urls = databaseAccess.getUrls();
adapter = new bgAdapter(getContext(), R.layout.row_layout);
adapterOriginal = new bgAdapter(getContext(), R.layout.row_layout);
databaseAccess.close();
listView.setAdapter(adapter);
int i = 0;
for(String name: boardgamesNames) {
boardgameListRow data = new boardgameListRow(urls.get(i), boardgamesNames.get(i));
i++;
adapter.add(data);
adapterOriginal.add(data);
}
listView.setDivider(null);
listView.setDividerHeight(0);
searchView = (SearchView)view.findViewById(R.id.searchId);
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
if (newText.length() > 0) {
adapter.getFilter().filter(newText);
}
return false;
}
});
searchView.setOnCloseListener(new SearchView.OnCloseListener() {
#Override
public boolean onClose() {
BoardGameListFragment fragment= new BoardGameListFragment();
FragmentTransaction fragmentTransaction = getFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.fragment_container,fragment);
fragmentTransaction.commit();
//adapter = adapterOriginal;
return true;
}
});
// Inflate the layout for this fragment
return view;
}
}
Here is the Adapter:

I think you need to call notifyDataSetChanged() in onQueryTextChange

I fixed it, I was using the wrong variable in bgAdapter. Please remove this question if possible.

How to pass a row in listview in a fragment to listview in another fragment in same activity when click button in row?

I have two fragments in one activity and there is a ViewPager element in main_activity.xml. I have created two different classes that exteds Fragment class for each fragments and overrided onCreateView methods. The first fragment is a channels list. So it's a listview that its each row consist of a textview and a button. I want when the user click the button, get passed the row to listView in second fragment. I created a interface in ChannelsFragment named FavButtonClickedListener and overrided this interface in MainActivity.java. Then I added onAttach() method into ChannelsFragment in order to reference MainActivity. In getView method of Adapter of ChannelsFragment class I have set the clicklistener to imageButtons in each row and I called whenFavButtonClicked.onFavButtonClicked(); My code is working for SharedPreferences hovewer I need to restart the application to see changes in favorites list. I want to add the rows dynamically. I don't know where I wrong please help me

Per the official documentation, fragment to fragment communication should be routed through the activity.
You need to create an interface in your channels fragment with some callback method defined, like onSelected. When a list item is selected, call that interface method using the activity context:
public class ChannelsFragment extends ListFragment {
OnItemSelectedListener mCallback;
public interface OnItemSelectedListener {
public void onSelected(int position);
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
try {
mCallback = (OnItemSelectedListener) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString()
+ " must implement OnItemSelectedListener");
}
}
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
mCallback.onSelected(position);
}
}
Then, your activity needs to implement ChannelFragment.OnItemSelectedListener and define the callback method.
public void onSelected(int position) {
Fragment2 fragment = (Fragment2)
getSupportFragmentManager().findFragmentById(R.id.fragment2);
if (fragment != null) {
fragment.updateValue(position);
}
}
You can pass data via parameters. To send the data to the other fragment, create a public method in the fragment which can be called directly from the activity.

It seems the values are not really being overwritten. Each time the second activity is loaded new part and type ArrayLists are being created. In these new lists only the latest part and type are added (in the onCreate Function) which have travelled with the intent.
If you want the list to keep adding the part and type selected by the user you can maintain the lists on the MainActivity. So upon selection of each item and type add it to the list on the MainActivity and then pass it to the ListViewItems activity.
This way the list will always have all the items selected by you.
I must admit I am not 100% sure if I understood your question correctly. But I have tried to answer with as much as I did.

How to perform search in the expandable listview which is in the fragment?

Here is the thing..
I have one activity in which i have implmented the ActionBarSherlock,View Pager with Tab Navigation.
In Action Bar i have placed the search view.Now i am adding the list of fragments from the activity using viewPagerAdapter.
Now, In fragments i have placed the expandable listview and i am display the products with its section name in the expandable listview.
What i want to do ::
I want to perform the search of products from the expandable listview.
Problem which i have faced ::
I have placed the searchview in the Activity from which i am calling the different fragments.So how to perform the search ???

I am actually getting the action bar in wrong way.
TO use the action bar in each fragment ::
i have placed the setHasOptionsMenu(true); in my onCreate() of fragment
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
After that i am able to use the onCreateOptionMenu() in which i placed the searchview and now i am able to search the date from the expandable listview,getting text from searchview.
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.menu, menu);
final MenuItem searchItem = menu.findItem(R.id.menu_item_search);
final SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setQueryHint("Search Here");
}
And now m done,Problem resolved.... ;)

How to implement search functionality?

I am having a grid view and I have to add search functionality in the action bar.So that whatever i type to search,the items should come whatever i searched.Grid view is having image and text.I stuck in this very badly.I dont know how to implement it.I gone through android guide but I unable to get it.
Please suggest some easy way to do it.I need search like in watsaap application.
Any suggestion is appreciated.Thanks.
Here is my gridview code.
public class FragmentDeals extends Fragment implements Checkable{
private boolean mChecked;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View layout = inflater.inflate(R.layout.fragmentdeal,
(ViewGroup)
findViewById(R.id.layoutdeal));
//View view = inflater.inflate(R.layout.griddeal,null);
final GridView mGrid = (GridView) layout.findViewById(R.id.GridDeal);
mGrid.setAdapter(new DealAdapter());
mGrid.setChoiceMode(GridView.CHOICE_MODE_MULTIPLE_MODAL);
