Android divider color DatePicker dialog

The following approach worked for me.This sets divider colours for all fields (also for am/pm)

 private void applyStyLing(TimePickerDialog timePickerDialog){
    Resources system = Resources.getSystem();
    int hourNumberPickerId = system.getIdentifier("hour", "id", "android");
    int minuteNumberPickerId = system.getIdentifier("minute", "id", "android");
    int ampmNumberPickerId = system.getIdentifier("amPm", "id", "android");

    NumberPicker hourNumberPicker = (NumberPicker) timePickerDialog.findViewById(hourNumberPickerId);
    NumberPicker minuteNumberPicker = (NumberPicker) timePickerDialog.findViewById(minuteNumberPickerId);
    NumberPicker ampmNumberPicker = (NumberPicker) timePickerDialog.findViewById(ampmNumberPickerId);

   setNumberPickerDividerColour(hourNumberPicker);
   setNumberPickerDividerColour(minuteNumberPicker);
   setNumberPickerDividerColour(ampmNumberPicker);
}

private void setNumberPickerDividerColour(NumberPicker number_picker){
    final int count = number_picker.getChildCount();

    for(int i = 0; i < count; i++){

        try{
            Field dividerField = number_picker.getClass().getDeclaredField("mSelectionDivider");
            dividerField.setAccessible(true);
                ColorDrawable colorDrawable = new ColorDrawable(mContext.getResources().getColor(R.color
                        .interactive_color));
            dividerField.set(number_picker,colorDrawable);

            number_picker.invalidate();
        }
        catch(NoSuchFieldException e){
            Log.w("setNumberPickerTxtClr", e);
        }
        catch(IllegalAccessException e){
            Log.w("setNumberPickerTxtClr", e);
        }
        catch(IllegalArgumentException e){
            Log.w("setNumberPickerTxtClr", e);
        }
    }
}

I solved this by doing this:

I changed the DatePicker divider with reflection by finding the "mSelectionDivider". Then I had problems with the Title divider looking stupid, so i added a textview above the LinearLayout containing the 3 datepickers and used newFragment.setTitle(""); to remove the original one.

Example:

    public DatePickerDialog makeDatePicker(OnDateSetListener listener, Calendar cal) {
    Calendar c;
    if (cal == null) {
        c = Calendar.getInstance();
    } else {
        c = cal;
    }
    int year = c.get(Calendar.YEAR);
    int month = c.get(Calendar.MONTH);
    int day = c.get(Calendar.DAY_OF_MONTH);
    DatePickerDialog newFragment = new DatePickerDialog(this, listener, year, month, day);

    // removes the original topbar:
    newFragment.setTitle(""); 

    // Divider changing:
    DatePicker dpView = newFragment.getDatePicker(); 
    LinearLayout llFirst = (LinearLayout) dpView.getChildAt(0);
    LinearLayout llSecond = (LinearLayout) llFirst.getChildAt(0);
    for (int i = 0; i < llSecond.getChildCount(); i++) {
        NumberPicker picker = (NumberPicker) llSecond.getChildAt(i); // Numberpickers in llSecond
        // reflection - picker.setDividerDrawable(divider); << didn't seem to work.
        Field[] pickerFields = NumberPicker.class.getDeclaredFields();
        for (Field pf : pickerFields) {
            if (pf.getName().equals("mSelectionDivider")) {
                pf.setAccessible(true);
                try {
                    pf.set(picker, getResources().getDrawable(R.drawable.np_numberpicker_selection_divider_orange));
                } catch (IllegalArgumentException e) {
                    e.printStackTrace();
                } catch (NotFoundException e) {
                    e.printStackTrace();
                } catch (IllegalAccessException e) {
                    e.printStackTrace();
                }
                break;
            }
        }
    }
    // New top:
    int titleHeight = 90;
    // Container:
    LinearLayout llTitleBar = new LinearLayout(this);
    llTitleBar.setOrientation(LinearLayout.VERTICAL);
    llTitleBar.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, titleHeight));

    // TextView Title:
    TextView tvTitle = new TextView(this);
    tvTitle.setText("Select a date");
    tvTitle.setGravity(Gravity.CENTER);
    tvTitle.setPadding(10, 10, 10, 10);
    tvTitle.setTextSize(24);
    tvTitle.setTextColor(Color.BLACK);
    tvTitle.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, titleHeight-2));
    llTitleBar.addView(tvTitle);

    // View line:
    View vTitleDivider = new View(this);
    vTitleDivider.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, 2));
    vTitleDivider.setBackgroundColor(getResources().getColor(R.color.crumblrOrange));
    llTitleBar.addView(vTitleDivider);

    dpView.addView(llTitleBar);
    FrameLayout.LayoutParams lp = (android.widget.FrameLayout.LayoutParams) llFirst.getLayoutParams();
    lp.setMargins(0, titleHeight, 0, 0);
    return newFragment;
