How to Implement Custom Action Bar with Custom Buttons in Android

Implementing a Custom Button Like a Custom View

To create a button as a custom view, simply declare an ImageButton in your custom action bar layout. This button can display an image without any text or border.

<code class="xml"><ImageButton
    android:id="@+id/custom_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/my_custom_image" /></code>

Drawing a Line on the Top of the ActionBar

To draw a line at the top of the action bar, create a thin horizontal View and set its background color.

<code class="xml"><View
    android:id="@+id/action_bar_line"
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="@android:color/black" /></code>

Implementing Buttons Without Separator Lines

You cannot completely remove the separator lines between action bar buttons using the standard methods. You have two options:

• Use Custom Buttons: Create your own custom buttons as described above and add a thin white stroke around each button to simulate a separator line.
• Use Stacked Tabs: Use stacked tabs in the action bar to create a row of buttons without visible separators. However, this requires setting android:showDividers to none for the tab layout, which may alter the tab appearance.
