android在ListView中使用自己的图像

我有10个图形需要显示在我的ListView中

我创建了一个这样的类

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;
 }

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

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

当我创建LayoutAdaptor对象时

我这样做

    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);

之后。。。。在我的适配器类中，我这样做

        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);
                        }

错误的信息是这样的

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;
 }

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

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

看这个…例子`
