NumberPicker has no theme

Question

I am trying to use a NumberPicker in a dialog.

When i add the NumberPicker to the view it looks like follows:

My xml-file for the Dialog looks pretty simple like this:

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


    <NumberPicker
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/numberPicker"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true" />
</RelativeLayout>

My code is simply:

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

LayoutInflater inflater = (LayoutInflater)builder.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
RelativeLayout inflated = (RelativeLayout)inflater.inflate(R.layout.dialog_button_delay, (ViewGroup)getView());

final NumberPicker pick = (NumberPicker) inflated.findViewById(R.id.numberPicker);
String[] minuteValues = new String[37];

for (int i = 0; i < minuteValues.length; i++) {
    minuteValues[i] = String.valueOf(i*5);
}
pick.setWrapSelectorWheel(false);
pick.setMinValue(0);
pick.setMaxValue(36);
pick.setDisplayedValues(minuteValues);
builder.setView(inflated);

Manifest file:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="de.familyfood.familyfood">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/Theme.AppCompat.Light.NoActionBar">
        <activity
            android:name=".MainActivity"
            android:label="@string/title_start">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".AddFoodActivity" />
        <activity
            android:name=".LoginActivity"
            android:label="@string/title_activity_login"/>
    </application>

</manifest>

Styles xml file:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>

</resources>

Adding android:theme="@android:style/Theme.Dialog" results in the following visual:

Does anyone have an idea why i can't use the MaterialDesign NumberPicker?

It seems to be a problem with the Visual Studio Android Emulator using Hyper-V.

Problem did not appear when installing the App on my mobile phone or in Android SDK emulator using HAXM.

Visual Studio? Anyway, you can accept your answer so that no one else comes here looking for an unanswered question to answer. – Kamran Ahmed Oct 30 '16 at 04:51
@KamranAhmed had to wait 24 hours to accept the answer. Yes, The Visual Studio Android Emulator is using a Hyper-V machine which is incredible fast. Good replacement if you need Hyper-V for other VMs and can't use the Android SDK emulator. – Styler2go Oct 30 '16 at 07:55
