how to change number picker style in android?

Question

I want to use the NumberPicker component-widget but Instead in the default Holo theme I need to replace the blue color with orange since that is the default color in my styl

Answer 1

I face this problem too, I use reflect to change the style

public class MyNumberPicker extends NumberPicker {
    public MyNumberPicker(Context context) {
        super(context);

        setNumberPickerDivider();
    }

    public MyNumberPicker(Context context, AttributeSet attrs) {
        super(context, attrs);

        setNumberPickerDivider();
    }

    public MyNumberPicker(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);

        setNumberPickerDivider();
    }

    @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
    public MyNumberPicker(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);

        setNumberPickerDivider();
    }

    @Override
    public void addView(View child) {
        super.addView(child);
        updateView(child);
    }

    @Override
    public void addView(View child, int index, android.view.ViewGroup.LayoutParams params) {
        super.addView(child, index, params);
        updateView(child);
    }

    @Override
    public void addView(View child, android.view.ViewGroup.LayoutParams params) {
        super.addView(child, params);
        updateView(child);
    }

    public void updateView(View view) {
        if (view instanceof EditText) {
            EditText et = (EditText) view;
            et.setTextColor(ContextCompat.getColor(getContext(), R.color.font_content));
            et.setTextSize(16);
        }
    }

    private void setNumberPickerDivider() {

        try {
            {
                Field field = NumberPicker.class.getDeclaredField("mSelectionDivider");
                field.setAccessible(true);
                field.set(this, ContextCompat.getDrawable(getContext(), R.drawable.horizontal_divider));
            }

            {
                Field field = NumberPicker.class.getDeclaredField("mSelectionDividerHeight");
                field.setAccessible(true);
                field.set(this, 1);
            }
        } catch (NoSuchFieldException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        }
    }
}
