    <p>I created a state-list selector file <code>item_bg_selector.xml</code> in the drawable folder like this :</p> <pre><code>&lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;item android:state_selected="true" android:drawable="@drawable/item_background_selected" /&gt; &lt;item android:state_focused="true" android:drawable="@drawable/item_background_selected" /&gt; &lt;item android:state_pressed="true" android:drawable="@drawable/item_background_selected" /&gt; &lt;item android:drawable="@android:color/transparent"/&gt; &lt;/selector&gt; </code></pre> <p>Then i define a style element </p> <pre><code>&lt;style name="Item"&gt; &lt;item name="android:layout_width"&gt;wrap_content&lt;/item&gt; &lt;item name="android:layout_height"&gt;wrap_content&lt;/item&gt; &lt;item name="android:background"&gt;@drawable/item_bg_selector&lt;/item&gt; &lt;/style&gt; </code></pre> <p>Then I try to create an <code>ImageButton</code> like this :</p> <pre><code> &lt;ImageButton style="@style/Item" android:id="@id/btn_home" android:src="@drawable/home_button" /&gt; </code></pre> <p>Eclipse keeps giving me the following error in the <code>Event Details</code> window : </p> <pre><code>Failed to parse file /path/to/projectdir/res/drawable/item_bg_selector.xml </code></pre> <p>The exception trace is given below :</p> <pre><code>org.xmlpull.v1.XmlPullParserException: Binary

I have cross checked this close to 15 times and still I have not been able to find the problem. I believe it is a very simple problem(if any). Any work around to get over with this is also appreciated.</p> <p>Addition : Also, line 16 in <code>item_bg_selector.xml</code> corresponds to the third line from the top in the file I have posted. that is </p> <pre><code>&lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;item android:state_selected="true" line16 ----&gt; android:drawable="@drawable/item_background_selected" /&gt; </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.
