The color of the buttons and other text can also be changed via theme:

values-21/styles.xml

<style name="AppTheme" parent="...">
  ...
  <item name="android:timePickerDialogTheme">@style/AlertDialogCustom</item>
  <item name="android:datePickerDialogTheme">@style/AlertDialogCustom</item>
  <item name="android:alertDialogTheme">@style/AlertDialogCustom</item>
</style>

<style name="AlertDialogCustom" parent="android:Theme.Material.Light.Dialog.Alert">
  <item name="android:colorPrimary">#00397F</item>
  <item name="android:colorAccent">#0AAEEF</item>
</style>

The result:

Dialog Date picker

Here s a natural way to do it with styles   If your AppTheme is inherited from Theme MaterialComponents  then    lt style name  AlertDialogTheme  parent  ThemeOverlay MaterialComponents Dialog Alert  gt       lt item name  buttonBarNegativeButtonStyle  gt  style NegativeButtonStyle lt  item gt       lt item name  buttonBarPositiveButtonStyle  gt  style PositiveButtonStyle lt  item gt   lt  style gt    lt style name  NegativeButtonStyle  parent  Widget MaterialComponents Button TextButton Dialog  gt       lt item name  android textColor  gt  f00 lt  item gt   lt  style gt    lt style name  PositiveButtonStyle  parent  Widget MaterialComponents Button TextButton Dialog  gt       lt item name  android textColor  gt  00f lt  item gt   lt  style gt    If your AppTheme is inherited from Theme AppCompat    lt style name  AlertDialogTheme  parent  ThemeOverlay AppCompat Dialog Alert  gt       lt item name  buttonBarNegativeButtonStyle  gt  style NegativeButtonStyle lt  item gt       lt item name  buttonBarPositiveButtonStyle  gt  style PositiveButtonStyle lt  item gt   lt  style gt    lt style name  NegativeButtonStyle  parent  Widget AppCompat Button ButtonBar AlertDialog  gt       lt item name  android textColor  gt  f00 lt  item gt   lt  style gt    lt style name  PositiveButtonStyle  parent  Widget AppCompat Button ButtonBar AlertDialog  gt       lt item name  android textColor  gt  00f lt  item gt   lt  style gt    Use your AlertDialogTheme in your AppTheme   lt item name  alertDialogTheme  gt  style AlertDialogTheme lt  item gt    or in constructor   androidx appcompat app AlertDialog Builder context  R style AlertDialogTheme

For me it was different  I used a button theme  lt style name  quot ButtonLight pink quot  parent  quot android Widget Button quot  gt       lt item name  quot android background quot  gt  drawable light pink btn default holo light lt  item gt       lt item name  quot android minHeight quot  gt 48dip lt  item gt       lt item name  quot android minWidth quot  gt 64dip lt  item gt       lt item name  quot android textColor quot  gt  color tab background light pink lt  item gt   lt  style gt   and because android textColor was white there    I didn t see any button text  Dialog buttons are basically buttons too   There we go  changed it  fixed it

In your app s theme style  add the following lines    lt item name  android buttonBarNegativeButtonStyle  gt  style NegativeButtonStyle lt  item gt   lt item name  android buttonBarPositiveButtonStyle  gt  style PositiveButtonStyle lt  item gt   lt item name  android buttonBarNeutralButtonStyle  gt  style NeutralButtonStyle lt  item gt   Then add the following styles    lt style name  NegativeButtonStyle  parent  Widget MaterialComponents Button TextButton Dialog  gt       lt item name  android textColor  gt  color red lt  item gt   lt  style gt    lt style name  PositiveButtonStyle  parent  Widget MaterialComponents Button TextButton Dialog  gt       lt item name  android textColor  gt  color red lt  item gt   lt  style gt    lt style name  NeutralButtonStyle   parent  Widget MaterialComponents Button TextButton Dialog  gt       lt item name  android textColor  gt  00f lt  item gt   lt  style gt     Using this method makes it unneccessary to set the theme in the AlertDialog builder

The simpliest solution is   dialog show      Only after  show   was called dialog getButton AlertDialog BUTTON NEGATIVE  setTextColor neededColor   dialog getButton AlertDialog BUTTON POSITIVE  setTextColor neededColor

If you want to change buttons text color  positive  negative  neutral  just add to your custom dialog style    lt item name  colorAccent  gt  color accent color lt  item gt    So  your dialog style must looks like this    lt style name  AlertDialog  parent  Theme AppCompat Light Dialog Alert  gt       lt item name  android textColor  gt  android color black lt  item gt       lt item name  colorAccent  gt  color topeka accent lt  item gt   lt  style gt

Just as a side note   The colors of the buttons  and the whole style  also depend on the current theme which can be rather different when you use either  android app AlertDialog Builder builder   new AlertDialog Builder     or  android support v7 app AlertDialog Builder builder   new AlertDialog Builder      Better to use the second one

There are two ways to change the dialog button color   Basic Way  If you just want to change in an activity  write the below two lines after alertDialog show     alertDialog getButton AlertDialog BUTTON POSITIVE  setTextColor getResources   getColor R color colorPrimary    alertDialog getButton AlertDialog BUTTON NEGATIVE  setTextColor getResources   getColor R color colorPrimaryDark      Recommended  I ll recommend adding a theme for AlertDialog in styles xml so you don t have to write the same code again and again in each activity dialog call  You can just create a style and apply that theme on the dialog box  So whenever you want to change the color of AlertDialog box  just change color in styles xml and all the dialog boxes will be updated in the whole application    lt style name  AlertDialogTheme  parent  Theme AppCompat Light Dialog Alert  gt       lt item name  colorAccent  gt  color colorPrimary lt  item gt   lt  style gt    And apply the theme in AlertDialog Builder  AlertDialog Builder builder   new AlertDialog Builder this  R style AlertDialogTheme

You can try to create the AlertDialog object first  and then use it to set up to change the color of the button and then show it   Note that on builder object instead of calling show   we call create   to get the AlertDialog object     1  create a dialog object  dialog  MyCustomDialog builder   new MyCustomDialog getActivity     Try Again   errorMessage    AlertDialog dialog   builder setNegativeButton  OK   new DialogInterface OnClickListener                       Override                 public void onClick DialogInterface dialogInterface  int i                                                              create       2  now setup to change color of the button dialog setOnShowListener  new OnShowListener          Override     public void onShow DialogInterface arg0            dialog getButton AlertDialog BUTTON NEGATIVE  setTextColor COLOR I WANT              dialog show     The reason you have to do it on onShow   and cannot just get that button after you create your dialog is that the button would not have been created yet    I changed AlertDialog BUTTON POSITIVE to AlertDialog BUTTON NEGATIVE to reflect the change in your question  Although it is odd that  OK  button would be a negative button  Usually it is the positive button
