    <p>I have the following problem, and searched for a while but haven't got any solution from the net: </p> <p>I have a custom list view, each item has the following layout (I just post the essential):</p> <pre><code>&lt;LinearLayout&gt; &lt;ImageView android:id="@+id/friendlist_iv_avatar" /&gt; &lt;TextView andorid:id="@+id/friendlist_tv_nick_name" /&gt; &lt;ImageView android:id="@+id/friendlist_iv_status_icon" /&gt; &lt;/LinearLayout&gt; </code></pre> <p>And I have a class FriendRowItem, which is inflated from the above layout:</p> <pre><code>public class FriendRowItem extends LinearLayout{ private ImageView ivAvatar; private ImageView ivStatusIcon; private TextView tvNickName; public FriendRowItem(Context context) { super(context); RelativeLayout friendRow = (RelativeLayout) Helpers.inflate(context, R.layout.friendlist_row); this.addView(friendRow); ivAvatar = (ImageView)findViewById(R.id.friendlist_iv_avatar); ivStatusIcon = (ImageView)findViewById(R.id.friendlist_iv_status_icon); tvNickName = (TextView)findViewById(R.id.friendlist_tv_nick_name); } public void setPropeties(Friend friend) { //Avatar ivAvatar.setImageResource(friend.getAvatar().getDrawableResourceId()); //Status Status.Type status = friend.getStatusType(); if ( status == Type.ONLINE) { ivStatusIcon.setImageResource(R.drawable.online_icon); } else { ivStatusIcon.setImageResource(R.drawable.offline_icon); } //Nickname String name = friend.getChatID(); if ( friend.hasName()) { name = friend.getName(); } tvNickName.setText(name); } } </code></pre> <p>In the main activity, I have a custom listview: lvMainListView, with an custom adapter (whose class extends ArrayAdapter - and off course: override the method getView ), the data set of the adapter is: <code>ArrayList&lt;Friend&gt; friends</code>:</p> <pre><code>private class FriendRowAdapter extends ArrayAdapter&lt;Friend&gt; { public FriendRowAdapter(Context applicationContext, int friendlistRow, ArrayList&lt;Friend&gt; friends) { super(applicationContext, friendlistRow, friends); } @Override public View getView(int position,View convertView,ViewGroup parent) { Friend friend = getItem(position); FriendRowItem row = (FriendRowItem) convertView; if ( row == null ) { row = new FriendRowItem(ShowFriendsList.this.getApplicationContext()); } row.setPropeties( friend ); return row; } } </code></pre> <ul> <li>the problem is when I change the status of a friend from OFFLINE to ONLINE, then call notifyDataSetChanged(), nothing happens : the status icon of that friend doesn't change.<br> I tried debugging, and saw the code: notifyDataSetChanged() get called, but the custom getView() is not fired ! </li> </ul> <p>Can you please tell me, that is normal in Android, or did I do something wrong ? (I am using Android 1.5).</p> <p>Thank you in advance,<br> Son</p>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
