如何在Android中使操作栏标签中心对齐？

Question

Android action bar tabs are left-aligned by default, I want to align it the center of the action bar. Is there any way we can make it center?

Answer 1

I was able to center-align the actionbar by customizing my application theme

In my AndroidManifest.xml, I added a android:theme property:

<application
        android:label="@string/app_name"
        android:icon="@drawable/ic_launcher"
        android:theme="@style/CustomActionBarTheme">
  ...

I then added a new themes.xml file to my project, and added :

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <!-- the theme applied to the application or activity -->
    <style name="CustomActionBarTheme"
           parent="@android:style/Theme.Holo.Light.DarkActionBar">
        <item name="android:actionBarTabBarStyle">@style/MyActionBarTabBar</item>
    </style>

    <style name="MyActionBarTabBar">
        <item name="android:gravity">center</item>
    </style>
</resources>

The tabs should now be center-aligned.

EDIT: It works only if your actionbar is displayed on 2 lines (in portrait)

Answer 2

You can use the ViewPagerIndicator plugin to customize your tabs.

Hope it helps!
