    <p>I need to load only the second item's image from a URL. I've searched for libraries and methods to make lists with URL images and text, but i only need the second item's image to be loaded. </p> <pre><code>public void prepareArrayLits() { menuItemList = new ArrayList&lt;Object&gt;(); AddObjectToList(R.drawable.icon_door, "Pet Open"); AddObjectToList(R.drawable.icon_profile_small, GlobalData.fullname); AddObjectToList(R.drawable.icon_messages, "Messages"); AddObjectToList(R.drawable.icon_people, "People"); AddObjectToList(R.drawable.icon_settings, "Settings"); AddObjectToList(R.drawable.icon_logout, "Log Out"); } </code></pre> <p>I wouldn't like to change the adapter, so what if i could change the second item's image after the list was made. Is there any way i could do this?</p> <p><em>other items images' from list cannot be loaded from url</em></p> <hr> <pre><code>@Override public Object getItem(int position) { // TODO Auto-generated method stub return menuItemList.get(position); } @Override public View getView(int position, View convertView, ViewGroup parent) { // TODO Auto-generated method stub ViewHolder holder; if(convertView==null) { holder = new ViewHolder(); convertView = inflater.inflate(R.layout.menu_drawer_left, null); holder.listMenuIcon = (ImageView) convertView.findViewById(R.id.ic_menu); holder.listMenuText = (TextView) convertView.findViewById(R.id.txt_menu); convertView.setTag(holder); } else holder=(ViewHolder)convertView.getTag(); MenuItemBean bean = (MenuItemBean) menuItemList.get(position); holder.listMenuIcon.setImageResource(bean.getMenuIcon()); holder.listMenuText.setText(bean.getMenuText()); return convertView; } </code></pre> <p>If the count starts from 0, i would like to change the item with id 1. How do i change it?</p>

    1. COWhy not change the adapter? I think you should change your adapter because of this: If you have 100 items in your list and maybe 20 need to load from a network source. How would you tell what item is currently visible in the list? Because loading all 20 while only 2 are visible is memory waste if you ask me. Imagine what would happen if you have 2000 items in you list that need to be loaded from a network source? It would kill your application. An adapter can automate inflating and loading resources for you in a very easy and memory friendly way. I would say: you SHOULD CHANGE your adapter.

I want to change the profile picture, which is downloaded from the server. but if i change the adapter would i be able to load others from drawable?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
