I can not add a style using the selector
<p>I have styles</p>

<pre><code>&lt;resources xmlns:android="http://schemas.android.com/apk/res/android"&gt;

&lt;style name="TextStyle" &gt; 
        &lt;item name="android:textSize"&gt;8sp&lt;/item&gt; 
        &lt;item name="android:textColor"&gt;#0A0A0A&lt;/item&gt; 
        &lt;item name="android:typeface"&gt;serif&lt;/item&gt; 

&lt;/style&gt;

 &lt;style name="TextStylePressed" &gt; 
        &lt;item name="android:textSize"&gt;18sp&lt;/item&gt; 
        &lt;item name="android:textColor"&gt;#0A0A0A&lt;/item&gt; 
        &lt;item name="android:typeface"&gt;serif&lt;/item&gt; 
        &lt;item name="android:textStyle"&gt;bold&lt;/item&gt; 
        &lt;item name="android:background"&gt;#C2C2C2&lt;/item&gt;   
&lt;/style&gt;

&lt;/resources&gt;
</code></pre>

<p>and I use selector arrow.xml</p>

<pre><code>&lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;

    &lt;item android:drawable="@style/TextStylePressed" android:state_selected="true"/&gt;
    &lt;item android:drawable="@style/TextStylePressed" android:state_pressed="true"/&gt;
    &lt;item android:drawable="@style/TextStylePressed" android:state_focused="true"/&gt;
    &lt;item android:drawable="@style/TextStyle" /&gt;

&lt;/selector&gt;
</code></pre>

<p><strong>The problem is that I can not understand - if it works?</strong> </p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    style="@drawable/arrow"               //  &lt;---- Framed here
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/arrow" //  &lt;---- then here
    android:orientation="vertical" &gt; 

&lt;/LinearLayout&gt;
</code></pre>

<p><strong>Consequently, after all attempts nothing happens</strong></p>
