The switch widget introduced in API 14 is styled by default with holo theme.
I want to style it slightly different, changing its colors and shape a bit for branding reasons. How does one go about this? I know it must be possible, as ive seen the difference between default ICS and Samsung's touchwiz theme
I assume I'll need some state drawables, and I've seen a few styles in http://developer.android.com/reference/android/R.styleable.html with Switch_thumb and Switch_track that look like what I might be after. I just don't know how to go about using them.
I'm using ActionbarSherlock if that makes a difference. Only devices running API v14 or above will be able to use a switch at all, of course.
You can define the drawables that are used for the background, and the switcher part like this:
<Switch
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:thumb="#drawable/switch_thumb"
android:track="#drawable/switch_bg" />
Now you need to create a selector that defines the different states for the switcher drawable.
Here the copies from the Android sources:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false" android:drawable="#drawable/switch_thumb_disabled_holo_light" />
<item android:state_pressed="true" android:drawable="#drawable/switch_thumb_pressed_holo_light" />
<item android:state_checked="true" android:drawable="#drawable/switch_thumb_activated_holo_light" />
<item android:drawable="#drawable/switch_thumb_holo_light" />
</selector>
This defines the thumb drawable, the image that is moved over the background. There are four ninepatch images used for the slider:
The deactivated version (xhdpi version that Android is using)
The pressed slider:
The activated slider (on state):
The default version (off state):
There are also three different states for the background that are defined in the following selector:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false" android:drawable="#drawable/switch_bg_disabled_holo_dark" />
<item android:state_focused="true" android:drawable="#drawable/switch_bg_focused_holo_dark" />
<item android:drawable="#drawable/switch_bg_holo_dark" />
</selector>
The deactivated version:
The focused version:
And the default version:
To have a styled switch just create this two selectors, set them to your Switch View and then change the seven images to your desired style.
It's an awesome detailed reply by Janusz. But just for the sake of people who are coming to this page for answers, the easier way is at http://android-holo-colors.com/ (dead link) linked from Android Asset Studio

However, I highly recommend everybody to read the reply from Janusz as it will make understanding clearer. Use the tool to do stuffs real quick
You can customize material styles by setting different color properties.
For example custom application theme
<style name="CustomAppTheme" parent="Theme.AppCompat">
<item name="android:textColorPrimaryDisableOnly">#00838f</item>
<item name="colorAccent">#e91e63</item>
</style>
Custom switch theme
<style name="MySwitch" parent="#style/Widget.AppCompat.CompoundButton.Switch">
<item name="android:textColorPrimaryDisableOnly">#b71c1c</item>
<item name="android:colorControlActivated">#1b5e20</item>
<item name="android:colorForeground">#f57f17</item>
<item name="android:textAppearance">#style/TextAppearance.AppCompat</item>
</style>
You can customize switch track and switch thumb like below image by defining xml drawables. For more information http://www.zoftino.com/android-switch-button-and-custom-switch-examples
Alternative and much easier way is to use shapes instead of 9-patches.

Using an ImageView / ImageButton (AppCompatImageView / AppCompatImageButton) in conjunction with a style attribute of android:tint which makes use of a ColorStateList resource works fine on >= API 21, but throws an InflateException on API < 21.
Firstly, I don't even know whether the AppCompatImageView / (Button) tinting supports ColourStateList xml resources as an android:tint value, I can't seem to find a definitive answer to this. Suggestions I can find on S/O suggest implementing a TintableImageView etc, but these answers are quite dated, and it seems from the source of the appcompat implementations this should be a feature.
To clarify this is definitely the issue. Removing the android:tint attribute or setting it to a single colour resource works.
Also to clarify, I'm aware this is achievable programmatically. I'm trying to get it backwards compatible in xml.
Minimal example
activity_foo.xml
<android.support.v7.widget.AppCompatImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_caret_up"
style="#style/IconButton.Primary"
/>
styles.xml
<style name="IconButton.Primary">
<item name="android:tint">#color/link_button_color</item>
</style>
link_button_color.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="#color/btnLinkPressedTextColor"
android:state_selected="true" />
<item android:color="#color/btnLinkPressedTextColor"
android:state_pressed="true" />
<item android:color="#color/btnLinkTextColor" />
</selector>
In my case i replaced android:tint with app:tint and added to root element xmlns:app="http://schemas.android.com/apk/res-auto". It fixed crashing issue on API level < 21.
And color state selector /res/color/color_selector.xml looks like:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#151515"/>
<item android:state_focused="true" android:color="#151515"/>
<item android:color="#424242"/>
</selector>
It looks like AppCompat drawable tinting only works for action bar and "some widgets" on < API 21, but works for all drawables on API 21+.
When you set these attributes, AppCompat automatically propagates their values to the framework attributes on API 21+. This automatically colors the status bar and Overview (Recents) task entry.
On older platforms, AppCompat emulates the color theming where possible. At the moment this is limited to coloring the action bar and some widgets.

item name="android:tint" is wrong.
fix the 'android:tint' to 'tint'
<style name="IconButton.Primary">
<item name="tint">#color/link_button_color</item>
</style>
I am having trouble changing the style of a Switch view in my project and can't figure out what I am doing wrong or missing... My project uses holo everywhere.
I can't change the text, the thumb or the track. I've tried applying android:thumb and android:track drawables directly from the xml but nothing changes. Not even the android:textOff and android:textOn have any effect.
I found a great post on how to customise the android Switch view style and looked through all the code but couldn't find anything I was doing wrong:
http://custom-android-dn.blogspot.co.uk/2013/01/how-to-use-and-custom-switch-in-android.html
Really not sure what else to try.
Here is the xml code:
<Switch
android:id="#+id/home_availability_switch"
style="#style/MySwitch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:enabled="true"
android:focusable="true"
android:textOff="Free"
android:textOn="Busy" />
Here is the style:
<style name="MySwitch" parent="#style/Holo.Switch.Light">
<item name="android:thumb">#drawable/selector_availability_switch_thumb</item>
<item name="android:track">#drawable/selector_availability_switch_background</item>
</style>
Here is the thumb selector
(these are default system drawables. i have tried with different drawables):
<item android:drawable="#drawable/switch_thumb_pressed_holo_light" android:state_pressed="true"/>
<item android:drawable="#drawable/switch_thumb_activated_holo_light" android:state_checked="true"/>
<item android:drawable="#drawable/switch_thumb_disabled_holo_light" android:state_enabled="false"/>
<item android:drawable="#drawable/switch_thumb_holo_dark"/>
Here is the track selector
(these are default system drawables. i have tried with different drawables):
<item android:drawable="#drawable/switch_bg_disabled_holo_dark" android:state_enabled="false"/>
<item android:drawable="#drawable/switch_bg_focused_holo_dark" android:state_focused="true"/>
<item android:drawable="#drawable/switch_bg_holo_dark"/>
I also found this post How can I style an Android Switch? and follow the instructions but had no luck.
Any one else had a similar experience when using Holo Everywhere?
You need to define the switch like this. Need the whole package name in there for it to work.
<org.holoeverywhere.widget.Switch
android:id="#+id/lockSwitch"
style="?switchStyleOld"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TestSwitch" />
Hope this helps.
I have some clickable views and I want to set the default available background that is present on list click (in ICS is a blue color). I have tried putting as background this:
android:background="#android:drawable/list_selector_background"
but it is not the default blue I have by default (the one I used is orange). What is the drawable used by default on android as click selector?
Thanks
This works for me:
android:background="?android:attr/selectableItemBackground"
It's list_selector_holo_dark or the equivalent holo light version; and these are the defaults in Honeycomb and above. list_selector_background is the non-holo version, used in Gingerbread and below.
EDIT: I believe (but can't confirm) that the platform agnostic selector is ?android:attr/listSelector
If you are using appcompat-v7, you can just use ?attr/selectableItemBackground.
There is a way to combine all the valid answers:
Define a attribute (eg. in values/attrs.xml):
<attr name="clickableItemBackground" format="reference"/>
In your platform dependent theme section (eg. in values/styles.xml or values/themes.xml) declare this:
<style name="Theme.Platform" parent="#android:style/Theme.Whatever">
<item name="clickableItemBackground">#android:drawable/list_selector_background</item>
</style>
In your platform dependent theme section for api-11+ (eg. in values-v11/styles.xml or values-v11/themes.xml) declare this:
<style name="Theme.Platform" parent="#android:style/Theme.Holo.Whatever">
<item name="clickableItemBackground">?android:attr/selectableItemBackground</item>
</style>
Then use ?attr/clickableItemBackground wherever needed.
A solution similar to flx's answer, but without additional attribute definition.
Platform independent style used for pre-Holo devices (in res\values\styles.xml):
<style name="SelectableItem">
<item name="android:background">#android:drawable/list_selector_background</item>
</style>
Style for Holo devices (API Level 14+) (in res\values-v14\styles.xml):
<style name="SelectableItem">
<item name="android:background">?android:attr/selectableItemBackground</item>
</style>
Apply style to needed view, e.g., LinearLayout:
<LinearLayout
style="#style/SelectableItem"
android:layout_width="match_parent"
android:layout_height="wrap_content">
...
</LinearLayout>
This works fine on api 11 and above. But as noted it wont work on previous versions.
android:background="?android:attr/selectableItemBackground"
Here is a solution to have it run on all versions running android.
Add the appropriate colors within the colors.xml which is located within your values folder. It should appear as such:
<color name="white">#ffffff</color>
<color name="blue">#7ecce8</color>
Create an xml selector file. Here I named it button_selection.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="#color/blue"/> <!--pressed -->
<item android:state_focused="true" android:drawable="#color/blue"/> <!-- focused -->
<item android:drawable="#color/white"/> <!-- default -->
</selector>
Go to your view or button and set the newly created button_selection.xml as its background.
android:background="#drawable/button_selection"
Alternatively,
android:background="?android:attr/listChoiceBackgroundIndicator
if you just want the items to highlight blue (or whatever the current default is) while they are clicked.
Setting Background restricts you from choosing a background color or drawable later!
So my advice is to add this style to your styles.xml:
<style name="TouchableView">
<item name="android:foreground">?android:attr/selectableItemBackground</item>
</style>
And then on every view you only need to add:
android:theme="#style/TouchableView"
Like ANY VIEW!
<TextView
android:id="#+id/my_orders"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginRight="0dp"
android:theme="#style/TouchableView"
android:background="#color/white"
android:gravity="left"
android:padding="10dp"
android:text="#string/my_orders"
android:textColor="#color/gray"
android:textSize="14sp" />
Don't forget to add onClickListener to see the results.
In short - android:background="?selectableItemBackground" ;)
The color of my Spinner widgets change from phone to phone based on there settings,I would like to keep them the same between all phones and I would like to have it be the default eclipse uses in its emulators the color is silverish. Can you please let me know how to apply this specific theme to my Spinner in xml. Thanks in advance.
download the images used in for the spinner from the android source code: spinner_press.9.png, spinner_select.9.png, spinner_normal.9.png then create selector using those.
this is the default selector:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="#drawable/spinner_press" />
<item android:state_pressed="false" android:state_focused="true"
android:drawable="#drawable/spinner_select" />
<item android:drawable="#drawable/spinner_normal" />
</selector>
You don't need to create a theme. Just apply a background of your choice to the spinner, as with any other View.
If you want to have different backgrounds you can use a (See here for more info)
For an example of an implementation, nothing better than the android source: https://android.googlesource.com/platform/frameworks/base/+/froyo-release/core/res/res/drawable/spinner_background.xml
You can get the actual 9-patch files from there also (and choose which version you would like to use).
