In GridView after filtering the list, the index changes and the context of item is wrong

I am having a GridList View in which I am passing data from firebase. When I click on the items it works fine without filtering but when I filter it with searchView then it does not update the index of the list and then provides a different item's context.
I do not know how to update the item while filtering.

Either implement a Filterable interface in the adapter or update your onQueryTextChange implementation.
Whenever you are typing, every time you are creating a new adapter with filtered data.
try this.. create new method in adapter
public void updateData(List<CategoryModelClass> catList){
this.catList = catList;
notifyDataSetChanged();
}
and call from onQueryTextChange
#Override
public boolean onQueryTextChange(String newText) {
//adapter.getFilter().filter(newText);
resultData = new ArrayList<>();
for (CategoryModelClass categoryModelClass : catList) {
if (categoryModelClass.getName().toLowerCase().contains(newText.toLowerCase())) {
resultData.add(categoryModelClass);
}
adapter.updateData(resultData);
}
return true;

I only want to send this "1" to the server C# by click the button for testing. I don't know why.

If you'd logged the Exception and watches the stacktrace, you would have seen a NetworkOnMainThreadException
You can't open network sockets on the UI thread (in onCreate), so you need to create either an AsyncTask or a Service.
