Android использовать собственное изображение в ListView

Мне нужно 10 графических изображений для отображения в моем ListView

и я создаю такой класс 

public class LayoutAdapterObj {
 public String addString;
 public ImageView leftImage;
 public String backgroundImageName;
 public LayoutAdapterObj(String addString,ImageView leftImageName,String backgroundImageName){
     this.addString = addString;
     this.leftImage = leftImageName;
     this.backgroundImageName = backgroundImageName;
 }

и когда я создаю объект LayoutAdaptor

Я делаю это 

    aArray.add(new LayoutAdapterObj("1",new ImageView(null, null, R.drawable.frame1),"R.drawable.layout"));
    aArray.add(new LayoutAdapterObj("2",new ImageView(null, null, R.drawable.frame2),"R.drawable.layout"));
    LayoutListAdapter m_adapter;
    m_adapter = new LayoutListAdapter(this, R.layout.topbarlayout, aArray);

после этого .... в моем классе адаптера я делаю это 

        public View getView(int position, View convertView, ViewGroup parent) {
                View v = convertView;
                if (v == null) {
                    LayoutInflater vi = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                        v = vi.inflate(R.layout.layout1, null);
                }
                LayoutAdapterObj o = items.get(position);
                if (o != null) {
                        TextView addText = (TextView) v.findViewById(R.id.addtext);                     
                        ImageView leftImage=(ImageView)v.findViewById(R.id.layoutframe);
                        if(!o.backgroundImageName.equals(""))
                        {

                        }
                        if(addText!=null)
                        {
                            addText.setText(o.addString);
                        }

неправильное сообщение, подобное этому 

java.lang.IllegalStateException: Could not execute method of the activity

if(leftImage != null)
{
    leftImage= o.leftImage;
}

посмотрите этот ... пример ... `

   class UserListAdapter extends ArrayAdapter<String> 
    {



        @Override
        public int getCount() {
            // TODO Auto-generated method stub
            int temp;
            if(SharedVariables.is_traffic_search_ON_flag){
                temp=search_cases_trafficTicketsList.size();
            }else{
                temp=search_cases_criminalTicketsList.size();
            }
            return temp;
        }

        Activity context;

        public UserListAdapter(Activity context) {
            super(context, 0);

            Log.d("hh","sgbdfjfdgfk");

            this.context = context;

    }`

вызовите свой адаптер следующим образом

UserListAdapter a = new UserListAdapter ();yurlistview.setAdapter (а);
