Answer 1

Try this, it might help you:

Edit your styles.xml as:

<style name="DialogTheme" parent="Theme.AppCompat.Light.Dialog">
       <item name="colorAccent">@color/white</item>
</style>

And add below lines to your code:

new DatePickerDialog(MainActivity.this, R.style.DialogTheme, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
    //DO SOMETHING
  }
}, 2015, 02, 26).show();

Answer 2

I am able to change the date color in the header giving a custom theme CustomDatePickerDialogTheme to my datePicker DialogFragment:

<style name="CustomDatePickerDialogTheme" parent="Theme.AppCompat.Light.Dialog">
    <item name="android:datePickerStyle">@style/CustomDatePickerStyle</item>
</style>

<style name="CustomDatePickerStyle" parent="@android:style/Widget.Material.Light.DatePicker">
    <item name="android:headerMonthTextAppearance">@style/HeaderTextStyle</item>
</style>

<style name="HeaderTextStyle" parent="@android:style/TextAppearance.Medium">
    <item name="android:textColor">@color/colorAccent</item>
</style>

Answer 3

Well I have no clue what's the parent theme that you have for your Date Picker theme. Let's say you have a custom theme for your Date Picker like below,

 <style name="yourCustomStyle" parent="Theme.AppCompat.Light">

Now Ctrl + click on Theme.AppCompat.Light which leads you to a new way ;) where you can find what you are looking for meaning here your issue is only about the head text but you might wish to change another views color, so that's the place you need to have a look.

And as the answer create a custom theme like below and add this attribute with the color you like

android:textColorPrimaryInverse

should do the trick for you.

   <style name="yourCustomStyle" parent="Theme.AppCompat.Light">
        <item name="colorAccent">@color/blue</item>
        <item name="android:textColorPrimaryInverse">@color/yellow</item>
        .. other
    </style>

Feel free to use your own colors and code(I copied code from this) and it will do the job!

new DatePickerDialog(MainActivity.this, R.style.yourCustomStyle, new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
      
    }
}, 2015, 02, 26).show();
