add filter
method in RecyclerView.Adapter
:
public void filter(String text) {
if(text.isEmpty()){
items.clear();
items.addAll(itemsCopy);
} else{
ArrayList<PhoneBookItem> result = new ArrayList<>();
text = text.toLowerCase();
for(PhoneBookItem item: itemsCopy){
//match by name or phone
if(item.name.toLowerCase().contains(text) || item.phone.toLowerCase().contains(text)){
result.add(item);
}
}
items.clear();
items.addAll(result);
}
notifyDataSetChanged();
}
itemsCopy
is initialized in adapter's constructor like itemsCopy.addAll(items)
.
If you do so, just call filter
from OnQueryTextListener
from SearchView
:
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
adapter.filter(query);
return true;
}
@Override
public boolean onQueryTextChange(String newText) {
adapter.filter(newText);
return true;
}
});
