If you want to create Item view function check below example. In the below example I have created a Advanced class. By using Advanced adpater many opretions can be consumed. In Advanced adapter we can easily use view holder method. Adapter call the getView() method which return a view for each item that is within the adapter view. In the below code i have described how to make Advanced adapter.

Step(1)- MainActivity-

public class MainActivity extends ListActivity{

   @Override

       protected void onCreate(Bundle savedInstanceState) {
           // TODO Auto-generated method stub
           super.onCreate(savedInstanceState);
           String str[] = new String[] {"C","C++","Java","Andorid"};
           AdvancedAdapter adapter = new AdvancedAdapter(this, str);
           setListAdapter(adapter);
}


}

Step(2)- Create a AdvancedAdapter class-

public class AdvancedAdapter extends ArrayAdapter<String> {
    private final Context context;
    private final String[] lang;


    public AdvancedAdapter(Context context, String lang[]) {
        super(context, R.layout.row, lang);
        this.context = context;
        this.lang = lang;
    }

    static class Holder {
        public TextView text;
        public ImageView img;

    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View row;
        if (convertView == null) {
            LayoutInflater li = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            row = li.inflate(R.layout.row, parent, false);
            Holder holder = new Holder();
            holder.text = (TextView) row.findViewById(R.id.label);
            holder.img = (ImageView) row.findViewById(R.id.icon);
            row.setTag(holder);
        } else
        {
            row = convertView;
        }
        Holder holder = (Holder) row.getTag();
        String str = lang[position];
        holder.text.setText(str);

        if (str.startsWith("C")) {
            holder.img.setImageResource(R.drawable.img1);

        } else if (str.startsWith("java")) {
            holder.img.setImageResource(R.drawable.img2);
        } else if (str.startsWith("android")) {
            holder.img.setImageResource(R.drawable.img2);
        } else
            holder.img.setImageResource(R.drawable.img1);

        return row;

    }
}

Step(3)-Create a new layout (row.xml)-

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" >

    <ImageView
        android:id="@+id/icon"
        android:layout_width="100px"
        android:layout_height="100px"
        android:layout_marginLeft="4px"
        android:layout_marginRight="10px"
        android:layout_marginTop="4px"
        android:src="@drawable/img1" >
    </ImageView>

    <TextView
        android:id="@+id/label"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@+id/label"
        android:textSize="80px" >
    </TextView>

</LinearLayout>
