如何更改 ActionBar Tab 的 textStyle？

Question

By default android actionBar Tab has text-style as CAPITAL. How can I set the text-style to normal camel-case style. Like "Abcd" instead of "ABCD"(Which is the by-default style)

Answer 1

To make the tab text lowercase, create a style that inherits Widget.Holo.Light.ActionBar.TabText Widget.Holo.ActionBar.TabText and set android:textAllCaps to false .

You can apply your own ActionBar.Tab text style by using the android:actionBarTabTextStyle attribute.

For AppCompat compatibility, your style should inherit Widget.AppCompat.Light.ActionBar.TabText or Widget.AppCompat.ActionBar.TabText and the attributes are the same as above, minus the android prefix.

For more information, you should read: Styling the ActionBar

Here's an example with AppCompat compatibility:

values

<style name="Your.Theme" parent="@style/Theme.AppCompat.Light">
    <item name="android:actionBarTabTextStyle">@style/Your.TabText.Style</item>
    <item name="actionBarTabTextStyle">@style/Your.TabText.Style</item>
</style>

<style name="Your.TabText.Style" parent="@style/Widget.AppCompat.Light.ActionBar.TabText">
    <item name="textAllCaps">false</item>
</style>

values-v14

<style name="Your.TabText.Style" parent="@android:style/Widget.Holo.Light.ActionBar.TabText">
    <item name="android:textAllCaps">false</item>
</style>

Apply custom theme to your app where you can change actionbar's properties.

<style name="Theme.MyAppTheme" parent="@android:style/Theme.Holo.Light">
    <item name="android:actionBarStyle">@style/MyActionBar</item>
</style>
<style name="MyActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
    <item name="android:textAppearance">?android:attr/textAppearanceSmall</item>
    <item name="android:textAllCaps">false</item>
</style>
