How can I Change TimePicker Text Color in xml or code

Question

I read this link about changing the text color of TimePicker but I didn't benefit from it

I used this code

<style name="MyTimePicker1" parent="@android:style/Widget.TimePicker">
        <item name="android:textColor">#000000</item>
    </style>

and I get this error

error: Error retrieving parent for item: No resource found that matches the given name '@android:style/Widget.TimePicker'.

I also tried this code

void applyFontRecursively(ViewGroup parent, Integer textColor) 
    {    
        for(int i = 0; i < parent.getChildCount(); i++)
        {
            View child = parent.getChildAt(i);            
            if(child instanceof ViewGroup) 
            {
                applyFontRecursively((ViewGroup)child, textColor);
            }
            else if(child != null)
            {


                     if(child instanceof TextView)
                    {
                         TextView textView = (TextView) child;
                         textView.setTextColor(textColor);

                    }
            }                
        }
    }

and I get this result
