changing image of imageview dynamically

Question

i have a list defined by the layout list_item_new.xml in which i have an imageView and 2 textViews. ImageView is defined like this

 <ImageView
        android:id="@+id/listimage"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"

        android:gravity="center"

        android:src="@drawable/users2"
    />

i am using the same ListView on 3 different screens. Now what i want is that the image on this imageView should be different for all the 3 screens. i am trying to change to image like this

LayoutInflater inflater = (LayoutInflater) this.getSystemService
             (Context.LAYOUT_INFLATER_SERVICE);
        LinearLayout ll = (LinearLayout) inflater.inflate(R.layout.list_item_new, null);
        listimg=(ImageView)ll.findViewById(R.id.listimage);
        listimg.setImageResource(R.drawable.office);

office.png is an image in drawable.

the whole code is executing but the image is not changing. please tell me what should i do to change the image. i am writing this code in onCreate method of activity and after this i am assigning the data to the list

thanks

Answer 1

see this class

public class Adapter extends SimpleAdapter{

public Adapter(Context context, List<? extends Map<String, String>> data,
        int resource, String[] from, int[] to) {
    super(context, data, resource, from, to);

}
@Override
public View getView(int position, View convertView, ViewGroup parent){
 View row = convertView;
 if (row == null) {
    LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    row ll = inflater.inflate(R.layout.list_item_new, null);
    listimg=(ImageView)ll.findViewById(R.id.listimage);
    listimg.setImageResource(R.drawable.office);

    textView=(TextView)ll.findViewById(R.id.<textViewID>);
    textView.setText("Hello");
 }

 return row;
}

}
