    <p>I have a preference screen that is populated with items from a database. I have this working by creating my own <code>PreferenceActivity</code>. In the activity I create <code>DialogPreference</code> items and add them to my <code>PreferenceCategory</code> To style to preference item on the screen I use a custom layout and apply it using <code>setLayoutResource(R.layout.custom_pref_row)</code></p> <p>This basically adds an <code>ImageButton</code> to the view aligned to the right of the layout. This all works fine and my preference screen shows the custom view with the button. My question is how do I attach a click listener to the button in the custom view? I was not able to find a way to get at <code>View</code> for the row from the <code>PreferenceActivity</code>. If my items were not created dynamically I might be able to do this all from XML and then reference the id or the button, but I can do that because I am creating the list dynamically.</p> <p>Any suggestions on how to get a handle on the <code>ImageButton</code> for each item? In the end I want to configure the button to launch a delete confirmation dialog.</p> <p>R.layout.custom_pref_row:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:minHeight="?android:attr/listPreferredItemHeight" android:gravity="center_vertical" android:paddingRight="?android:attr/scrollbarSize"&gt; &lt;RelativeLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="15dip" android:layout_marginRight="6dip" android:layout_marginTop="6dip" android:layout_marginBottom="6dip" android:layout_weight="1"&gt; &lt;TextView android:id="@+android:id/title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:singleLine="true" android:textAppearance="?android:attr/textAppearanceLarge" android:ellipsize="marquee" android:fadingEdge="horizontal" /&gt; &lt;TextView android:id="@+android:id/summary" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@android:id/title" android:layout_alignLeft="@android:id/title" android:textAppearance="?android:attr/textAppearanceSmall" android:maxLines="2" /&gt; &lt;ImageButton android:id="@+id/pref_delete_station" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ic_trash_can" android:layout_alignParentRight="true" android:background="@null"&gt;&lt;/ImageButton&gt; &lt;/RelativeLayout&gt; &lt;!-- Preference should place its actual preference widget here. --&gt; &lt;LinearLayout android:id="@+android:id/widget_frame" android:layout_width="wrap_content" android:layout_height="fill_parent" android:gravity="center_vertical" android:orientation="vertical" /&gt; &lt;/LinearLayout&gt; </code></pre> <p>Related part of my PreferenceActivity:</p> <pre><code>DialogPreference diaPref; for (Station mStation : sList) { diaPref = new StationEditor(this.getPreferenceScreen().getContext(), null, this, mStation); diaPref.setLayoutResource(R.layout.custom_pref_row); diaPref.setTitle(mStation.getName()); diaPref.setKey(STATION_PREFIX + mStation.getId()); // add new preference stationTypesCategory.addPreference(diaPref); } </code></pre>

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.
