Segmented control button for Android

Implementation of a segmented control button for Android. A Segmented Control is really a better looking and more touch friendly version of a RadioButton. In fact, this implementation inherits from Android's default RadioButton.

The controls are customizable and themed in the fashion of the stock controls in Android 4.0 (Ice Cream Sandwich) and above.

The project contains a sample activity that shows how the buttons are implemented and styled.

Usage

You can use this library either with a theme or without a theme. With a theme is much easier but here are examples for both.

Theme

You can add the widget styles to your Theme in themes.xml and whenever you use either SegmentedControlButton or TabControlButton the theme will be automatically set!

values-v11/themes.xml:

<style name="CustomTheme" parent="@android:style/Theme.Holo">
    <item name="segmentedControlButtonStyle">@style/Widget.Holo.SegmentedControl</item>
    <item name="tabControlButtonStyle">@style/Widget.Holo.TabControl</item>
</style>

values/themes.xml:

<style name="CustomTheme" parent="@android:style/Theme">
    <item name="segmentedControlButtonStyle">@style/Widget.Holo.SegmentedControl</item>
    <item name="tabControlButtonStyle">@style/Widget.Holo.TabControl</item>
</style>

And in your layout:

<RadioGroup
    android:id="@+id/buttongroup1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal" >

    <at.bookworm.widget.TabControlButton
        android:id="@+id/option1"
        android:text="Button 1" />

    <at.bookworm.widget.TabControlButton
        android:id="@+id/option2"
        android:text="Button 2" />
</RadioGroup>

No Theme

Instead of RadioButton, use either SegmentedControlButton or TabControlButton and set the widget's style to either Widget.Holo.SegmentedControlButton or Widget.Holo.TabControlButton. Since you aren't using a theme, you will have to set the style on every SegmentedControlButton and TabControlButton.

In your layout:

<RadioGroup
    android:id="@+id/buttongroup1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal" >

    <at.bookworm.widget.TabControlButton
        android:id="@+id/option1"
        android:text="Button 1"
        style="@style/Widget.Holo.TabControlButton" />

    <at.bookworm.widget.TabControlButton
        android:id="@+id/option2"
        android:text="Button 2"
        style="@style/Widget.Holo.TabControlButton" />
</RadioGroup>
