android utilisation propre image dans ListView

Question

J'ai 10 besoins graphiques à afficher dans mon ListView

et je crée une classe comme cette

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; 
} 

et quand je crée un objet LayoutAdaptor

je ce

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); 

après que .... dans ma classe d'adaptateur, je le fais

 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); 
         } 

le mauvais message est comme ce

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

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

appeler votre adaptateur comme celui-ci

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