title: Custom Button style is appearing in preview but not on device
body: <p>I made a custom style for my buttons. It is perfectly appearing in Layout Preview (through Android Studio XML Preview) but when I'm running the app, the button has not the wanted borders.</p>
  
  <p>Any idea of the reason(s) that may cause this ?</p>
  
  <p>activity_main.xml</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;style name="Button.Pink" parent="Button"&gt;
      &lt;item name="android:background"&gt;@drawable/rounded_corners_button&lt;/item&gt;
      &lt;item name="android:backgroundTint"&gt;@color/pink&lt;/item&gt;
      &lt;item name="android:textColor"&gt;@color/white&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  
  
  <p>styles.xml</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;Button
      style="@style/Button.Pink"
      android:id="@+id/btn_sale"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_gravity="top|start"
      android:enabled="false"
      android:foreground="?attr/selectableItemBackground"
      android:text="@string/sale"
      android:layout_marginTop="4dp"
      android:layout_marginStart="4dp"
      android:visibility="gone"
      tools:visibility="visible" /&gt;
  </code></pre>
  
  
  
  <p>rounded_corners_button.xml</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;item&gt;
          &lt;shape android:shape="rectangle"&gt;
              &lt;corners android:radius="65dp" /&gt;
          &lt;/shape&gt;
      &lt;/item&gt;
  &lt;/selector&gt;
  </code></pre>
