<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical" >

    <net.simonvt.widget.NumberPicker
        android:id="@+id/numberPicker"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    <Button
        android:id="@+id/buttonPickerEkle"
        android:layout_width="wrap_content"

It appears you imported:

import android.widget.NumberPicker;

But you want meant to use:

import net.simonvt.widget.NumberPicker;
