How can I override TimePicker to change text color

Question

My view has a white background, and it has to stay that way. I have a TimePicker on that white background.Everything is woking fine with android 2.3.3 but android 4.0.3 has a new timePicker style. The numbers have a very bright color. It is very hard to see them on the white background, and I didn't find a direct way to change the textColor. I don't want to change the background because it would look not so good.

Is there any way to override this and set the color of the numbers to black?

Take a look at the android source for styles.xml

https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/styles.xml

You then set a style on your activity/timepicker it looks like you could do something like this:

<style name="MyTimePicker" parent="@android:style/Widget.TimePicker">
    <item name="android:textColor">#000000</item>
</style>

or maybe (3.0 and above only)

<style name="MyHoloTimePicker" parent="@android:style/Widget.Holo.TimePicker">
    <item name="android:textColor">#000000</item>
</style>

Then your xml would be:

<TimePicker
 style="@style/MyHoloTimePicker"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent" />

@Demean yes, why would you think you couldn't? – Horripilation

Okay I added this to my styles.xml:<resources> <!-- Global Theme Styles --> <eat-comment /> <style name="Widget.TimePicker"> <item name="android:layout">@android:layout/time_picker</item> </style> <style name="Widget.Holo.TimePicker" parent="Widget.TimePicker"> <item name="android:layout">@android:layout/time_picker_holo</item> </style> <style name="Widget.Holo.Light.TimePicker" parent="Widget.Holo.TimePicker"> </style> </resources> error: Error retrieving parent for item: No resource found that matches the given name 'Widget' – Demean

@Demean all you've done is copy and paste out of the source, thats not what I said do. My answer shows you inherit from the source and override what you need – Horripilation

inherit what? You should post actual working cod that should work. i tried your code snippet myself and tried to locate the timePicker class on styles/Widget but there is no resource for it. – Treadle

it is there android.googlesource.com/platform/frameworks/base/+/refs/heads/… – Horripilation

Answer 2

use this function

public static boolean setNumberPickerTextColor(NumberPicker numberPicker, int color) {
final int count = numberPicker.getChildCount();
for (int i = 0; i < count; i++) {
  View child = numberPicker.getChildAt(i);
  if (child instanceof EditText) {
    try {
      Field selectorWheelPaintField =
          numberPicker.getClass().getDeclaredField("mSelectorWheelPaint");
      selectorWheelPaintField.setAccessible(true);
      ((Paint) selectorWheelPaintField.get(numberPicker)).setColor(color);
      ((EditText) child).setTextColor(color);
      numberPicker.invalidate();
      return true;
    } catch (NoSuchFieldException e) {
      Log.w("setNumberPickerTextColor", e);
    } catch (IllegalAccessException e) {
      Log.w("setNumberPickerTextColor", e);
    } catch (IllegalArgumentException e) {
      Log.w("setNumberPickerTextColor", e);
    }
  }
}
return false;
