I want to add a custom height to the dropdown of a Spinner, say 30dp, and I want to hide the dividers of the dropdown list of Spinner.

So far I tried to implement following style to the Spinner:

<style name="spinner_style">
        <item name="android:paddingLeft">0dp</item>
        <item name="android:dropDownWidth">533dp</item>
        <item name="android:showDividers">none</item>
        <item name="android:dividerHeight">0dp</item>
        <item name="android:popupBackground">@drawable/new_bg</item>
        <item name="android:dropDownHeight">70dp</item>
        <item name="android:scrollbarAlwaysDrawVerticalTrack">true</item>
        <item name="android:dropDownSelector">@android:color/white</item>
 </style>

and the code of my spinner is :

<Spinner
            android:id="@+id/pioedittxt5"
            android:layout_width="543dp"
            android:layout_height="63dp"
            android:layout_toRightOf="@+id/piotxt5"
            android:background="@drawable/spinner"
            style="@style/spinner_style"
            android:dropDownVerticalOffset="-53dp"
            android:spinnerMode="dropdown"
            android:drawSelectorOnTop="true"
            android:entries="@array/travelreasons"
            android:prompt="@string/prompt" />

But nothing seems to be working.
