Check if your activity layout overrides the theme  look for your activity layout located at layout  your activity  xml and look for TextView that contains android textColor   some hex code   something like that on activity layout  and remove it  Then run your code again

When you create an App  a file called styles xml will be created in your res values folder  If you change the styles  you can change the background  text color  etc for all your layouts  That way you don   t have to go into each individual layout and change the it manually   styles xml         lt resources xmlns android  http   schemas android com apk res android  gt   lt style name  Theme AppBaseTheme  parent   android style Theme Light  gt       lt item name  android editTextColor  gt  295055 lt  item gt        lt item name  android textColorPrimary  gt  295055 lt  item gt       lt item name  android textColorSecondary  gt  295055 lt  item gt       lt item name  android textColorTertiary  gt  295055 lt  item gt       lt item name  android textColorPrimaryInverse  gt  295055 lt  item gt       lt item name  android textColorSecondaryInverse  gt  295055 lt  item gt       lt item name  android textColorTertiaryInverse  gt  295055 lt  item gt         lt item name  android windowBackground  gt  drawable custom background lt  item gt           lt  style gt    lt  -- Application theme  -- gt   lt style name  AppTheme  parent  AppBaseTheme  gt       lt  -- All customizations that are NOT specific to a particular API-level can go here  -- gt   lt  style gt      parent   android style Theme Light  is Google   s native colors  Here is a reference of what the native styles are  https   android googlesource com platform frameworks base   refs heads master core res res values themes xml  The default Android style is also called    Theme     So you calling it Theme probably confused the program   name  Theme AppBaseTheme  means that you are creating a style that inherits all the styles from parent   android style Theme Light   This part you can ignore unless you want to inherit from AppBaseTheme again         lt style name  AppTheme  parent  AppBaseTheme  gt    drawable custom background is a custom image I put in the drawable   s folder  It is a 300x300 png image    295055 is a dark blue color   My code changes the background and text color  For Button text  please look through Google   s native stlyes  the link I gave u above     Then in Android Manifest  remember to include the code      lt application android theme   style Theme AppBaseTheme  gt

In your Manifest you need to reference the name of the style that has the text color item inside it  Right now you are just referencing an empty style  So in your theme xml do only this style    lt style name  Theme  parent   android style TextAppearance  gt       lt item name  android textColor  gt  ffffffff lt  item gt   lt  style gt    And keep you reference to in the Manifest the same  android theme   style Theme    EDIT   theme xml    lt style name  MyTheme  parent   android style TextAppearance  gt       lt item name  android textColor  gt  ffffffff lt  item gt       lt item name  android textSize  gt 12dp lt  item gt   lt  style gt    Manifest    lt application     android icon   drawable icon      android label   string app name      android theme   style MyTheme  gt    Notice I combine the text color and size into the same style  Also  I changed the name of the theme to MyTheme and am now referencing that in the Manifest  And I changed to  android style TextAppearance for the parent value

You can t use  android style TextAppearance as the parent for the whole app s theme  that s why koopaking3 s solution seems quite broken   To change default text colour everywhere in your app using a custom theme  try something like this  Works at least on Android 4 0   API level 14     res values themes xml    lt resources gt           lt style name  MyAppTheme  parent  android Theme Holo Light  gt           lt  -- Change default text colour from dark grey to black -- gt           lt item name  android textColor  gt  android color black lt  item gt       lt  style gt   lt  resources gt    Manifest    lt application             android theme   style MyAppTheme  gt    Update  A shortcoming with the above is that also disabled Action Bar overflow menu items use the default colour  instead of being greyed out   Of course  if you don t use disabled menu items anywhere in your app  this may not matter    As I learned by asking this question  a better way is to define the colour using a drawable    lt item name  android textColor  gt  drawable default text color lt  item gt       with res drawable default text color xml specifying separate state enabled  false  colour    lt selector xmlns android  http   schemas android com apk res android  gt       lt item android state enabled  false  android color   android color darker gray   gt       lt item android color   android color black   gt   lt  selector gt
