Note  Using Android Support Library v22 1 0 and targeting API level 11 and up  Scroll down to the last update        My application style is set to Theme Holo which is dark and I would   like the check boxes on my list view to be of style Theme Holo Light    I am not trying to create a custom style  The code below doesn t seem   to work  nothing happens at all    At first it may not be apparent why the system exhibits this behaviour  but when you actually look into the mechanics you can easily deduce it  Let me take you through it step by step   First  let s take a look what the Widget Holo Light CompoundButton CheckBox style defines  To make things more clear  I ve also added the  regular   non-light  style definition    lt style name  Widget Holo Light CompoundButton CheckBox  parent  Widget CompoundButton CheckBox    gt    lt style name  Widget Holo CompoundButton CheckBox  parent  Widget CompoundButton CheckBox    gt    As you can see  both are empty declarations that simply wrap Widget CompoundButton CheckBox in a different name  So let s look at that parent style    lt style name  Widget CompoundButton CheckBox  gt       lt item name  android background  gt  android drawable btn check label background lt  item gt       lt item name  android button  gt  android attr listChoiceIndicatorMultiple lt  item gt   lt  style gt    This style references both a background and button drawable  btn check label background is simply a 9-patch and hence not very interesting with respect to this matter  However   android attr listChoiceIndicatorMultiple indicates that some attribute based on the current theme  this is important to realise  will determine the actual look of the CheckBox   As listChoiceIndicatorMultiple is a theme attribute  you will find multiple declarations for it - one for each theme  or none if it gets inherited from a parent theme   This will look as follows  with other attributes omitted for clarity     lt style name  Theme  gt       lt item name  listChoiceIndicatorMultiple  gt  android drawable btn check lt  item gt           lt  style gt    lt style name  Theme Holo  gt       lt item name  listChoiceIndicatorMultiple  gt  android drawable btn check holo dark lt  item gt           lt  style gt    lt style name  Theme Holo Light  parent  Theme Light  gt       lt item name  listChoiceIndicatorMultiple  gt  android drawable btn check holo light lt  item gt           lt  style gt    So this where the real magic happens  based on the theme s listChoiceIndicatorMultiple attribute  the actual appearance of the CheckBox is determined  The phenomenon you re seeing is now easily explained  since the appearance is theme-based  and not style-based  because that is merely an empty definition  and you re inheriting from Theme Holo  you will always get the CheckBox appearance matching the theme   Now  if you want to change your CheckBox s appearance to the Holo Light version  you will need to take a copy of those resources  add them to your local assets and use a custom style to apply them   As for your second question      Also can you set styles to individual widgets if you set a style to the application    Absolutely  and they will override any activity- or application-set styles      Is there any way to set a theme style with images  to the checkbox   widget        Is there anyway to use this selector  link      Update   Let me start with saying again that you re not supposed to rely on Android s internal resources  There s a reason you can t just access the internal namespace as you please   However  a way to access system resources after all is by doing an id lookup by name  Consider the following code snippet   int id   Resources getSystem   getIdentifier  btn check holo light    drawable    android      CheckBox  findViewById R id checkbox   setButtonDrawable id     The first line will actually return the resource id of the btn check holo light drawable resource  Since we established earlier that this is the button selector that determines the look of the CheckBox  we can set it as  button drawable  on the widget  The result is a CheckBox with the appearance of the Holo Light version  no matter what theme style you set on the application  activity or widget in xml  Since this sets only the button drawable  you will need to manually change other styling  e g  with respect to the text appearance   Below a screenshot showing the result  The top checkbox uses the method described above  I manually set the text colour to black in xml   while the second uses the default theme-based Holo styling  non-light  that is        Update2   With the introduction of Support Library v22 1 0  things have just gotten a lot easier  A quote from the release notes  my emphasis       Lollipop added the ability to overwrite the theme at a view by view level by using the android theme XML attribute - incredibly useful for things such as dark action bars on light activities  Now  AppCompat allows you to use android theme for Toolbars  deprecating the app theme used previously  and  even better  brings android theme support to all views on API 11  devices    In other words  you can now apply a theme on a per-view basis  which makes solving the original problem a lot easier  just specify the theme you d like to apply for the relevant view  I e  in the context of the original question  compare the results of below    lt CheckBox             android theme   android style Theme Holo    gt    lt CheckBox             android theme   android style Theme Holo Light    gt    The first CheckBox is styled as if used in a dark theme  the second as if in a light theme  regardless of the actual theme set to your activity or application   Of course you should no longer be using the Holo theme  but instead use Material

The correct way to do it for Material design is     Style     lt style name  MyCheckBox  parent  Theme AppCompat Light  gt         lt item name  colorControlNormal  gt  color foo lt  item gt       lt item name  colorControlActivated  gt  color bar lt  item gt   lt  style gt      Layout     lt CheckBox       android layout width  wrap content      android layout height  wrap content      android checked  true      android text  Check Box      android theme   style MyCheckBox   gt    It will preserve Material animations on Lollipop
