This problem is caused because of overlapping fragments and i was starting the fragment like this
fragment=ProductFragment.newInstance();
getSupportFragmentManager().beginTransaction()
.replace(R.id.productFragment,fragment )
.commit();
so making it simply
fragment=ProductFragment.newInstance();
solved my problem.
Thanks guys for help #MohammadAllam

update your adapter use SparseBooleanArray

this.originalList.addAll(fullUsers);
booleanArray = new SparseBooleanArray();
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
.
.
.
final FullUser group =getItem(position);
holder.groupid.setText(group.getId());
holder.checkBox.setOnCheckedChangeListener(null);
holder.checkBox.setChecked(booleanArray.get(group.getId().hashCode(),false));
holder.checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
booleanArray.put(group.getId().hashCode(), isChecked);
}
});
.
.
.
return row;
}
public ArrayList<FullUser> getSelectedItems() {
ArrayList<FullUser> list = new ArrayList<>();
for(FullUser group:fullUsers){
if(booleanArray.get(group.getId().hashCode(), false)){
list.add(group);
}
}
return list;
};

Un-filtering the result is not working in Recyclerview

I have a recyclerview with some data and I have a searchview, and filter is working just fine. But un-filtering not working. I can't get the whole data in the recyclerview after un-filter. No data is showing. I have to re-open the activity to get data. I tried to used two data sets. But i have no idea where to use them.

Just Modify your function and Add check for null or "" .
it will work fine
private ArrayList<SuggestGetSet> filter(ArrayList<SuggestGetSet> models, String query) {
if(TextUtils.isEmpty(query)){
return models;
}
query = query.toLowerCase();
final ArrayList<SuggestGetSet> filteredModelList = new ArrayList<>();
for (SuggestGetSet model : models) {
final String text = model.getName().toLowerCase();
if (text.contains(query)) {
filteredModelList.add(model);
}
}
return filteredModelList;
}

RecyclerView filter not working

I have used this solution to filter my RecyclerView. Using the solution I was able to get the result while typing. But when I clear the search widget I don't get the full list instead I get the empty RecyclerView.
This is how my result looks like.

}
private List<Contact> filter(List<Contact> models, String query) {
query = query.toLowerCase();
if(query.equals("")) { return contactArrayList; }
final List<Contact> filteredModelList = new ArrayList<>();
for (Contact model : models) {
final String text = model.name.toLowerCase();
if (text.contains(query)) {
filteredModelList.add(model);
}
}
return filteredModelList;
}
Can anyone help me please?

assuming contactsList is var with the full contacts
private List<Contact> filter(List<Contact> models, String query) {
query = query.toLowerCase();
if(query.equals("")) { return contactsList; }
final List<Contact> filteredModelList = new ArrayList<>();
for (Contact model : models) {
final String text = model.name.toLowerCase();
if (text.contains(query)) {
filteredModelList.add(model);
}
}
return filteredModelList;
}

He has defined in this way:
public void setModels(List<ExampleModel> models) {
mModels = new ArrayList<>(models);
}
Initialize like the way he has done.
Your soultion would be:
this.contactsList = new ArrayList<>(contactsList);

You need to move your filter() method from your Activity to your Adapter. At your Adapter add one additional variable to hold a copy of unfiltered dataset. In your case, you need contactsList and copyOfContactsList variables.
Change your Adapter's constructor as follows:
public class ContactsAdapter extends RecyclerView.Adapter<ContactViewHolder> {
....
private ArrayList<Contact> contactsList = new ArrayList<>();
private ArrayList<Contact> copyOfContactsList = new ArrayList<>();
....
public ContactsAdapter(Context context, ArrayList<Contact> dataSet, boolean fromMyContacts){
...
this.contactsList = dataSet;
copyOfContactsList.addAll(dataSet);
...
}
and this is the filter method to be added to your Adapter:
public void filter(String text) {
if(text.isEmpty()){
contactsList.clear();
contactsList.addAll(copyOfContactsList);
} else{
ArrayList<Contact> result = new ArrayList<>();
text = text.toLowerCase();
for(Contact item: copyOfContactsList){
if(item.getName().toLowerCase().contains(text)){
result.add(item);
}
}
contactsList.clear();
contactsList.addAll(result);
}
notifyDataSetChanged();
}

SearchView and Recyclerview, showing right cards, but at the same time others are removed permanently

I'm trying to implement searchview. It works somehow, but the problem is that after you start typing it is one-way street. You get the info but if you delete text, you won't get the result as it was in the beginning. I'm working with cardviews.
Marker is a model(gettitle etc.)

Thanks for the help.

Wow, fixed the problem. The problem was that the arraylist wasn't declared as final. So now that i did that it works :).
Example:
before:
List<ExampleModel> mModels;
after:
private final List<ExampleModel> mModels;

These are both of the classes for this Product list please if you need more information please comment
Thanks in advance
There are two classes and those take products from my json and assign it to view holder

This problem is caused because of overlapping fragments and i was starting the fragment like this
fragment=ProductFragment.newInstance();
getSupportFragmentManager().beginTransaction()
.replace(R.id.productFragment,fragment )
.commit();
so making it simply
fragment=ProductFragment.newInstance();
solved my problem.
Thanks guys for help #MohammadAllam

I have this issue too after many search i fixed it whit update gradle dependencies i think its happened because one of old android dependencies.
