Есть ли способ добавить два текстовых изображения к массиву

Question

Я хочу использовать два textviews бок о бок в моем listview, а также выполнить поиск по ним. Есть ли способ сделать это без создания нового класса? Вот то, что я сделал до сих пор:

public class MainActivity extends Activity { 
final String[] elename ={"Hydrogen","Helium","Lithium","Beryllium","Boron","Carbon","Nitrogen","Oxygen","Fluorine","Neon","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","Iodine","Xenon","Caesium","Barium","Lanthanum","Cerium","Praseodymium","Neodymium","Promethium","Samarium","Europium","gadoliium","Terbium","Dysprosium","Holmium","Erbium","Thulium","Ytterbium","Lutetium","Hafnium","Tantalum","Tungsten","Rhenium","Osmium","Iridium","Platinum","Gold","Mercury","Thallium","Lead","Bismuth","Polonium","Astatine","Radon","Francium","Radium","Actinium","Thorium","Protactinium","Uranium","Neptunium","Plutonium","Americium","Curium","Berkelium","Californium","Einsteinium","Fermium","Mendelevium","Nobelium","Lawrencium","Rutherfordium","Dubnium","Seaborgium","Bohrium","Hassium","Meitnerium","Darmstadtium","Roentgenium","Copernicium","Ununtrium","Ununquadium","Ununpentium","Ununhexium","Ununseptium","Ununoctium"}; 
final String[] nos = {"1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24","25","26","27","28","29","30","31","32","33","34","35","36","37","38","39","40","41","42","43","44","45","46","47","48","49","50","51","52","53","54","55","56","57","58","59","60","61","62","63","64","65","66","67","68","69","70","71","72","73","74","75","76","77","78","79","80","81","82","83","84","85","86","87","88","89","90","91","92","93","94","95","96","97","98","99","100","101","102","103","104","105","106","107","108","109","110","111","112","113","114","115","116","117","118"}; 

ArrayAdapter<String> adapter; 

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


    adapter = new ArrayAdapter<String>(this, R.layout.list_item,R.id.element_name, elename); 
    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); 


    navList.setOnItemClickListener(new AdapterView.OnItemClickListener(){ 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, final int pos,long id){ 
      //Change view according to numbers 

      drawer.closeDrawer(linearLayout); 
     } 
    }); 

    //filter list view after search instantly 
    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 s) { 
     } 
    }); 

    //hide the keyboard after search on touch list view 
    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)); 

    } 
} 

Линия:

adapter = new ArrayAdapter<String>this,R.layout.list_item,R.id.element_name,elename); 

присвоить значение final String[] elename к textview в моем макете. Итак, есть ли способ добавить еще один textview и присвоить ему значение final String[] nos в той же строке или без необходимости создания нового класса ?.

Извините, если это глупый вопрос, но я новичок!

http://developer.android.com/reference/android/widget/ArrayAdapter.html

Вы можете сделать, как показано ниже picke d от ответа Патрикс @ How to construct and display the info in simple_list_item_2?

new ArrayAdapter (context, android.R.layout.simple_list_item_2, android.R.id.text1, list) 
    { 
    public View getView(int position, View convertView, ViewGroup parent) { 
     View view = super.getView(position, convertView, parent); 
     TextView text1 = (TextView) view.findViewById(android.R.id.text1); 
     TextView text2 = (TextView) view.findViewById(android.R.id.text2); 
     text1.setText(elename[positon]); 
     text2.setText(nos[position]); 
     return view; 
    } 
    }); 

Или используйте CustomAdapter простирающуюся ArrayAdapter

class CustomAdapter extends ArrayAdapter<String> 
    { 
     String A[],B[]; 
     LayoutInfalter mInfalter;  
     public CustomAdapter(Context context, String[] A,String B[]) 
     { 
      super(context,R.layout.customlayout,A); 
      this.A = A; 
      this.B = B; 
      mInfalter = LayoutInfalter.from(context); 
     } 
     public View getView(int position, View convertView, ViewGroup parent) { 
      ViewHolder holder; 
      if(convertView==null) 
      { 
       convertView = mInflater.inflate(R.layout.customlayout,parent,false); 
       holder = new ViewHolder(); 
       holder.tv1 = (TextView)convertView.findViewById(R.id.textView1); 
       holder.tv2 = (TextView)convertView.findViewById(R.id.textView2); 
       convertView.setTag(holder); 
      }else{ 
       holder = (ViewHolder)convertVire.getTag(); 
      } 

       holder.tv1.setText(A[positon]); 
       holder.tv2.setText(B[position]); 
      return convertVIew; 
    } 
    static class ViewHolder 
    { 
     TextView tv1,tv2; 
    }  
    } 

Есть макет customlayout.xml с 2 TextViews с идентификатором textView1 и TextView 2 repectively.

Тогда

CustomAdapter cus = new CustomAdapter(ActivityName.this,elename,nos); 
navList.setAdapter(cus);
