        return false;
    }

    public List<PS> filter (List<PS> psLists,String s){
        s = s.toLowerCase();
        filteredPs = new ArrayList<>();
        for (PS psList : psLists){
        final String text = psList.getCommandName().toString().toLowerCase();
        if (text.contains(s));
            filteredPs.add(psList);
        }
        psList = realm.where(PS.class).contains("commandName",s).findAll();
        adapterPS = new AdapterPS(ActivityPS.this,psList,realm);
        recyclerView.setLayoutManager(new LinearLayoutManager(ActivityPS.this));
        recyclerView.setAdapter(adapterPS);

        return filteredPs;
    }
}

Quiero buscar a través de mi reino DB y quiero que mi vista de búsqueda no es sensible a mayúsculas y minúsculas. Lo hice pero muestra sólo los datos minúsculas en consecuencia si inserto con mayúsculas o minúsculas. No sé lo que debo hacer ...

Me acaba de encontrar .... cambio mi código a este y funciona.

public class ActivityPS extends AppCompatActivity {
private PS_DA ps_da = new PS_DA(ActivityPS.this);
RecyclerView recyclerView;
android.widget.SearchView searchView;
Realm realm = Realm.getDefaultInstance();
AdapterPS adapterPS;
List<PS> filteredPs;
RealmResults<PS> psList;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_ps);
    cast();
    setUpRecycler();
    searchviewSetUp();
}

public void searchviewSetUp(){
    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String s) {

    return false;
}

@Override
public boolean onQueryTextChange(String s) {

   psList = realm.where(PS.class).contains("commandName",s, Case.INSENSITIVE).findAll();
    adapterPS = new AdapterPS(ActivityPS.this,psList,realm);
    recyclerView.setLayoutManager(new LinearLayoutManager(ActivityPS.this));
    recyclerView.setAdapter(adapterPS);


    return false;
}

Eso .Case.INSENSITIVEhizo que automáticamente.
