Create your own BaseAdapter class and use it as following        public class NotificationScreen extends Activity     Override protected void onCreate Impl Bundle savedInstanceState        setContentView R layout notification screen        ListView notificationList    ListView  findViewById R id notification list       NotiFicationListAdapter notiFicationListAdapter   new NotiFicationListAdapter        notificationList setAdapter notiFicationListAdapter        homeButton    Button  findViewById R id home button           Make your own BaseAdapter class and its separate xml file   public class NotiFicationListAdapter  extends BaseAdapter   private ArrayList lt HashMap lt String  String gt  gt  data  private LayoutInflater inflater null    public NotiFicationListAdapter ArrayList data    this data data              inflater   LayoutInflater baseActivity getSystemService Context LAYOUT INFLATER SERVICE        public int getCount       return data size         public Object getItem int position      return position       public long getItemId int position         return position       public View getView int position  View convertView  ViewGroup parent     View vi convertView      if convertView  null       vi   inflater inflate R layout notification list item  null        ImageView compleatImageView  ImageView vi findViewById R id complet image       TextView name    TextView vi findViewById R id game name      name     TextView email id    TextView vi findViewById R id e mail id      email ID     TextView notification message    TextView vi findViewById R id notification message      notification message        compleatImageView setBackgroundResource R id address book       name setText data getIndex position        email id setText data getIndex position        notification message setTextdata getIndex position         return vi           BaseAdapter xml file    lt RelativeLayout xmlns android  http   schemas android com apk res android  android id    id inner layout  android layout width  fill parent  android layout height  wrap content  android layout marginBottom  5dp  android layout marginLeft  10dp  android layout weight  4  android background   drawable list view frame  android gravity  center vertical  android padding  5dp   gt    lt TextView     android id    id game name      android layout width  wrap content      android layout height  wrap content      android text  Game name      android textColor   FFFFFF      android textSize  15dip      android textStyle  bold      android typeface  sans    gt    lt TextView     android id    id e mail id      android layout width  wrap content      android layout height  wrap content      android layout below   id game name      android layout marginTop  1dip      android text  E-Mail Id      android textColor   FFFFFF      android textSize  10dip    gt    lt TextView     android id    id notification message      android layout width  wrap content      android layout height  wrap content      android layout below   id game name      android layout toRightOf   id e mail id      android paddingLeft  5dp      android text  Notification message      android textColor   FFFFFF      android textSize  10dip    gt      lt ImageView     android id    id complet image      android layout width  wrap content      android layout height  wrap content      android layout alignParentRight  true      android layout centerVertical  true      android layout marginBottom  30dp      android layout marginRight  10dp      android src   drawable complete tag      android visibility  invisible    gt    lt  RelativeLayout gt    Change it accordingly and use

I suggest using a custom Adapter  first create a Xml-file  for example layout customlistview xml   lt  xml version  1 0  encoding  utf-8   gt   lt RelativeLayout xmlns android  http   schemas android com apk res android  android layout width  fill parent  android layout height  wrap content   gt       lt ImageView         android id    id image          android layout alignParentRight  true          android paddingRight  4dp    gt       lt TextView         android id    id title          android layout toLeftOf   id image          android layout width  wrap content          android layout height  wrap content          android textSize  23sp          android maxLines  1    gt       lt TextView         android id    id subtitle          android layout toLeftOf   id image  android layout below   id title          android layout width  wrap content          android layout height  wrap content    gt    lt  RelativeLayout gt    Assuming you have a custom class like this  public class CustomClass        private long id      private String title  subtitle  picture       public CustomClass                 public CustomClass  long id  String title  String subtitle  String picture            this id   id          this title  title          this subtitle  subtitle          this picture  picture              add getters and setters     And a CustomAdapter java uses the xml-layout  public class CustomAdapter extends ArrayAdapter    private Context context  private int resource  private LayoutInflater inflater   public CustomAdapter  Context context  List lt CustomClass gt  values       or String     or whatever      super context  R layout customlistviewitem  values        this context   context      this resource   R layout customlistview      this inflater   LayoutInflater from context       Override public View getView int position  View convertView  ViewGroup parent         convertView    RelativeLayout  inflater inflate resource  null        CustomClass item    CustomClass  getItem position        TextView textviewTitle    TextView  convertView findViewById R id title       TextView textviewSubtitle    TextView  convertView findViewById R id subtitle       ImageView imageview    ImageView  convertView findViewById R id image          fill the textviews and imageview with the values     textviewTitle   item getTtile        textviewSubtitle   item getSubtitle         if  item getAfbeelding      null            int imageResource   context getResources   getIdentifier  drawable     item getImage    null  context getPackageName             Drawable image   context getResources   getDrawable imageResource             imageview setImageDrawable image        return convertView            Did you manage to do it  Feel free to ask if you want more info on something     EDIT  Changed the adapter to suit a List instead of just a List
