액션 바의 버튼과 모양을 사용자 정의하는 방법은 무엇입니까?

<code class="xml"><Button
    android:id="@+id/my_custom_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/my_image" /></code>

<code class="xml"><style name="MyActionButtonStyle" parent="Widget.ActionButton">
    <item name="android:minWidth">28dip</item>
</style></code>

<code class="java">// Inflating custom layout
ViewGroup actionBarLayout = (ViewGroup) getLayoutInflater().inflate(R.layout.action_bar, null);

// Customizing ActionBar
ActionBar actionBar = getActionBar();
actionBar.setDisplayShowHomeEnabled(false);</code>
