How to Implement a Custom Action Bar with Buttons in Android?

Implementing a Custom Action Bar with Customized Buttons in Android

Creating a custom ActionBar allows for the personalization of an application's user interface, providing visual consistency and enhanced user experience. This guide will address three key aspects:

1. Creating a Custom Action Bar View

To incorporate a custom view within the ActionBar, follow these steps:

• Inflate your custom layout: Create a custom Action Bar layout (e.g., action_bar.xml) and inflate it using the LayoutInflater.
• Set up the ActionBar: Configure the ActionBar to enable custom views and set the inflated layout as the custom view.

2. Adding a Dividing Line to the Top of the ActionBar

While the ActionBar doesn't offer a built-in feature for adding a color strip at its top, you can use merge to include a separate layout in your main layout.

3. Implementing Buttons without Separator Lines

Using Tabs:

You can utilize the ActionBar's tabbed interface to create buttons without separators. However, this may not provide the desired appearance.

Clearing Separators:

Alternatively, you can define a button-specific style that eliminates separator lines altogether.

Example Implementation

The following code demonstrates the described implementation:

<code class="xml"><!-- Action Bar Custom Layout -->
<LinearLayout>
    <Button id="action_bar_title" />
    <Button id="action_bar_sent" />
    <Button id="action_bar_staff" />
    <Button id="action_bar_locations" />
</LinearLayout>

<!-- Button Style -->
<style name="ActionBarButton">
    <item name="android:background">@null</item>
    <item name="android:singleLine">true</item>
</style></code>

<code class="java">// ActionBar Configuration
ActionBar actionBar = getActionBar();
actionBar.setDisplayShowHomeEnabled(false);</code>
