I am using some list item layout and in the item layout, there is a Viewstub where I want to put some image in.I don't have the source of list item layout and just know there are some TextViews and ViewStubs in it.

My purpose is to find the ViewStub first and set my personal layout and play with it. However, some of the ViewStub cannot be found.

public class TJAdapter extends CursorAdapter {
    ....
    public void bindView(View view, Context context, Cursor cursor) {
        ViewStub contentstub = (ViewStub)item.findViewById(R.id.content_stub);

    if (contentstub == null){
        LOG.error("TJ,contentstub is null");
    } else  {
        LOG.error("TJ,contentstub is not null");
        contentstub.setLayoutResource(R.layout.icon_image);
        View iconImage = contentstub.inflate();
    }
    ....
}

public View newView(Context context, Cursor cursor, ViewGroup parent) {
    final View view = mInflater.inflate(R.layout.list_item, parent, false);
    bindView(view, context, cursor);
}

And the log output is like this:

 TJ,bindView is called
 TJ,contentstub is not null
 TJ,bindView is called
 TJ,contentstub is null
 TJ,bindView is called
 TJ,contentstub is not null
 TJ,bindView is called
 TJ,contentstub is not null
 TJ,bindView is called
 TJ,contentstub is null
 TJ,bindView is called
 TJ,contentstub is not null

I spent a lot of time on it and have no idea why this happens.

Can some body help?
