you are setting the non holo theme so you get the non holo numberpicker.
see this as reference, its basically the same thing you asked

I found 2 built-in NumberPickers:
(source: techbooster.org)
By default, it's the first one, but when I add android:theme="@android:style/Theme.NoTitleBar"
in AndroidManifest.xml, it becomes the second one.
How can I put this line (I need it) and still get the first NumberPicker?

The problem is that @android:style/Theme
is the Android theme for devices on API version 10 (2.3) and lower.
If you want to keep Holo support, you should use @android:style/Theme.Holo
.
If you need to support devices without Holo as well, you will need to create asset folders for those devices and specify the theme there.
You can use:
android:theme="@android:style/Theme.Holo.NoActionBar"
if you don't want to display the ActionBar and still get Holo-styled NumberPicker.
Have a superclass named as BaseActivity which gets extended by all the activities in your app. In it's onCreate call this
requestWindowFeature(Window.FEATURE_NO_TITLE);
It'll remove the title bar from all of your activities and you can use whatever theme you want. The only drawaback you'll get is the title bar will appear for a fraction of second when launching your app, but won't be seen again.
Additionally you can change also the following properties:
Your numberpicker definition in exampleActivity.xml
<NumberPicker
<!-- ... -->
android:background="@drawable/customshape" />
The drawable/customshape.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<gradient
android:startColor="@color/numberpicker_color_range_start"
android:endColor="@color/numberpicker_color_range_end"
android:angle="270"/>
</shape>
solidColor ... is the main holo color and a background with a customshape to get additional coloring:
