How to change Number Picker center text color in Android

Question

I have implemented a custom Date Picker wherein I need to have custom colors for the number picker (Date picker uses Number picker inside) inside it as follows:

With the help of this answer I could make it look like this:

But as you see the actual date is getting shown in the yellow color instead of white. Moreover, I tried doing it at run time like this:

npMonth.setOnValueChangedListener(new OnValueChangeListener() {

            @Override
            public void onValueChange(NumberPicker picker, int oldVal, int newVal) {
                EditText et = ((EditText) npMonth.getChildAt(0));
                et.setTextColor(getResources().getColor(R.color.gold));
            }
        });

But still no luck.

How to change just the center text color to white and keep the top and bottom text yellow?

Answer 1

The easiest way to do this

setNumberPickerTextColor(mNumberPicker);

public void setNumberPickerTextColor(NumberPicker numberPicker){
    int color=Color.parseColor("#333333");

    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();
            }
            catch(NoSuchFieldException e){
                Log.e("setNumberPickerColor1", ""+e);
            }
            catch(IllegalAccessException e){
                Log.e("setNumberPickerColor2", ""+e);
            }
            catch(IllegalArgumentException e){
                Log.e("setNumberPickerColor3", ""+e);
            }
        }
    }
}
