    <p>I'm working on a list of news items. My list is an <code>Activity</code> that extends <code>ListActivity</code>. I've also created an <code>ArrayAdapter</code> that I use to inflate the elements of my list. The <code>ArrayAdapter</code> uses a simple layout with an <code>ImageView</code> and two <code>TextView</code>s. Everything works but when I override the <code>onListItemClick()</code> method of the and try to resize the list elements when I click on them nothing happens.</p> <pre><code>protected void onListItemClick(ListView l, View v, int position, long id) { v.getLayoutParams().height=300; } </code></pre> <p>I've tried the above with <code>LayoutParams</code> as well</p> <p>Here is the layout of each row that I use to populate my list:</p> <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="100dp" android:background="@color/white" &gt; &lt;ImageView android:id="@+id/icon" android:layout_width="80dp" android:layout_height="80dp" android:layout_marginLeft="4dp" android:layout_marginRight="10dp" android:layout_marginTop="4dp" android:src="@drawable/ic_launcher" &gt; &lt;/ImageView&gt; &lt;LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical" &gt; &lt;TextView android:id="@+id/title1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@+id/label" android:textColor="@color/black" android:textColorHint="@color/black" android:textSize="10dp" android:textStyle="bold" &gt; &lt;/TextView&gt; &lt;TextView android:id="@+id/label" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@+id/label" android:textColor="@color/black" android:textColorHint="@color/black" android:textSize="10dp" &gt; &lt;/TextView&gt; &lt;/LinearLayout&gt; &lt;/LinearLayout&gt; </code></pre> <p>Has anyone faced the same issue? Can anyone cast some light for a beginner in Android?</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.
