Backwards compatible Switch

Question

ICS has a Switch component. It does what we need. Is there anything out there backward compatible to (about) 2.2? Couldn't find anything obvious.

Looks like somebody built this:

Answer 1

Android support AppCompat library from version 21.0.0 contains android.support.v7.widget.SwitchCompat to provide compability back to API v7. https://developer.android.com/reference/android/support/v7/widget/SwitchCompat.html

Include it like this with gradle:

compile 'com.android.support:appcompat-v7:21.0.0'

It can be used in layouts like this:

<android.support.v7.widget.SwitchCompat />

In addition it has showText attribute to make styling easier - which seems to be missing from native andriod Switch.

Answer 2

Switch is only on 4.0+

If you want to make an app that uses switch on 4.0+ devices what you need to do is declare two layouts. The first in layout-v14 which will be what's used on ICS devices. In your layout folder make use of CheckBox.

In your code make use of the CompoundButton class when getting/setting data from the switch or checkbox. You'll find that CompoundButton works well for this.
