    <p><strong>res/layout-v11/cell.xml</strong></p> <p>If you need to develop your application only API level 11 later, All you have to do is to write like following xml code.</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:background="?android:attr/activatedBackgroundIndicator" android:orientation="vertical"&gt; &lt;TextView android:id="@+id/name" android:layout_width="fill_parent" android:layout_height="wrap_content"/&gt; &lt;TextView android:id="@+id/text" android:layout_width="fill_parent" android:layout_height="wrap_content"/&gt; &lt;/LinearLayout&gt; </code></pre> <p><strong>res/layout/cell.xml</strong></p> <p>But, in API level &lt;= 10, the above code takes crashes.

    2. COThis code is actually running on my own application. It's no matter what you use BaseAdapter or any other Adapters. When a list item data is assign, it needs to determine that the data is already selected or not and change color of list item view.

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.

SQuiL has stopped working due to an internal error.

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