Игнорировать пробелы во время поиска listview android

Question

Я использую edittext и listview в своем приложении. Я реализовал функцию поиска и сделал edittext панель поиска. Я использую TextWatcher для мгновенного обнаружения изменений. Но когда я ввожу пробел в edittext, все listview предметов исчезли. Итак, как же я игнорировать пробелы, вводимые пользователем в edittext:

public class MainActivity extends FragmentActivity { 

final String[] data ={"Hydrogen","Helium","Lithium","Beryllium","Boron","Carbon","Nitrogen","Oxygen","Flourine","Noen","Sodium","Magnesium","Aluminium","Silicon","Phosphorous","Sulphur","Chlorine","Argon","Potassium","Calcium","Scandium","Titanium","Vanadium","Chromium","Manganese","Iron","Cobalt","Nickel","Copper","Zinc","Gallium","Germanium","Arsenic","Selenium","Bromine","Krypton","Rubidium","Strontium","Yttrium","Zirconium","Niobium","Molybdenum","Technetium","Ruthenium","Rhodium","Palladium","Silver","Cadmium","Indium","Tin","Antimony","Tellurium",

ArrayAdapter<String> adapter; 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, data); 
    final EditText searchBar = (EditText) findViewById(R.id.searchbar); 
    final DrawerLayout drawer = (DrawerLayout)findViewById(R.id.drawer_layout); 
    final ListView navList = (ListView) findViewById(R.id.left_drawer); 
    final LinearLayout linearLayout = (LinearLayout)findViewById(R.id.left_drawer_layout); 
    navList.setAdapter(adapter); 

    searchBar.addTextChangedListener(new TextWatcher() { 

     @Override 
     public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) { 
      // When user changed the Text 
      MainActivity.this.adapter.getFilter().filter(cs); 
     } 

     @Override 
     public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, 
             int arg3) { 

     } 

     @Override 
     public void afterTextChanged(Editable arg0) { 
     } 
    }); 

    navList.setOnScrollListener(new AbsListView.OnScrollListener() { 
     public void onScrollStateChanged(AbsListView view, int scrollState) { 
      //hide keyboard 
      InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE); 
      imm.hideSoftInputFromWindow(navList.getWindowToken(), 0); 
     } 

     public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) { 
     } 
    }); 

    navList.setEmptyView(findViewById(R.id.empty)); 

    } 
}

просто логика не реализована пробуем в

onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) { 

     convert the cs to string replace space(" ") with "" and then MainActivity.this.adapter.getFilter().filter(cs);
