Android Switch Widget Backport
A backport of the Switch widget (http://developer.android.com/reference/android/widget/Switch.html) that was introduced on Android 4.
This port works on Android 2.1+.
How to use
This is an Android library project, you have to add it as a dependency to your project (please see http://developer.android.com/guide/developing/projects/projects-eclipse.html#ReferencingLibraryProject to know how to do that.)
Once you have done that, have a theme for your application (or Activity), that declares the
to be one of the two possible themes: either
Widget.Holo.CompoundButton.Switch (dark) or
The simplest way to do that is to create a
themes.xml file in your project's
res/values folder with this contents:
<?xml version="1.0" encoding="utf-8"?> <resources> <style name="Theme" parent="@android:Theme"> <item name="switchStyle">@style/Widget.Holo.CompoundButton.Switch</item> </style> </resources>
Then in your layout xml files you can use the widget like this:
<org.jraf.android.backport.switchwidget.Switch android:layout_width="wrap_content" android:layout_height="wrap_content" />
Add switchPreferenceStyle to your 'themes.xml'
<?xml version="1.0" encoding="utf-8"?> <resources> <style name="Theme" parent="@android:Theme"> <item name="switchStyle">@style/Widget.Holo.CompoundButton.Switch</item> <item name="switchPreferenceStyle">@style/Preference.SwitchPreference</item> </style> </resources>
Then in your preference xml file:
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" xmlns:switchpref="http://schemas.android.com/apk/res-auto" > <org.jraf.android.backport.switchwidget.SwitchPreference android:key="testKey" android:title="SwitchPreference Test" switchpref:switchTextOff="@string/off" switchpref:switchTextOn="@string/on" switchpref:summaryOff="@string/summary_off" switchpref:summaryOn="@string/summary_on" /> </PreferenceScreen>
The code was copied directly from the Android 4.0.3 (API 15) source code, then slightly tweaked by myself (BoD@JRAF.org) to make it run on 2.1+. The few modifications I made are documented in the code (look for 'XXX' comments). The SwitchPreference part was added later by Intrications (intrications.com / github.com/intrications), also by taking code from Android and tweaking it a bit.
