                    <gradient android:angle="90" android:endColor="#B3BBCC" android:startColor="#E8EBEF" android:type="linear" />

                    <stroke android:width="1dp" android:color="#000000" />

                    <corners android:radius="4dp" />

                    <padding android:bottom="3dp" android:left="3dp" android:right="3dp" android:top="3dp" />
                </shape></item>

@drawable/spinner_arrow is your bottom right corner image

Spinner - how to set border around drop down list?

for custom border you can create an xml file inside drawable folder

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="@color/white_overlay_8x" />
    <corners android:radius="6dip" />
    <stroke
        android:color="@color/white"
        android:width="@dimen/dot" />

</shape>

and set

android:background=@drawable/file;

in your spinner(xml file of activity)

Change spinner background color but keep arrow

For the record, I found an easy solution : Wrap your spinner in a relative layout and add an image :

 <RelativeLayout 
     android:layout_width="fill_parent"
     android:layout_height="wrap_content"
     android:background="@drawable/borderbottom_white"<!-- white background with bottom border -->
     android:layout_marginTop="15dp"  >
        <Spinner
        android:id="@+id/postfield_category"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textSize="16sp"
        android:background="@null"
        android:minHeight="0dp" />
        <ImageView 
         android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:src="@drawable/arrowspinner" />
    </RelativeLayout>

How to create android spinner without down triangle on the right side of the widget

One thing you can do is take Spinner's source code from android code base, together with related layouts and resources, and use them to create your own custom widget (probably you will only need to remove the arrow from the layout and tweak the code a little depending on your needs).

EDIT:
You're right, following that post it was actually really simple :) You have to do two things.
First, create a styles.xml file under res/values, open it and add the following:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style parent="@android:style/Widget.Spinner" name="SpinnerAsEditText">
        <item name="android:background">@android:drawable/edit_text</item>
    </style>
</resources>

Next, in your layout, add the Spinner like this:

<Spinner style="@style/SpinnerAsEditText" anyOtherAttributeYouNeed="..."></Spinner>

That's it, now the spinner will look like a plain EditText, without that unuseful and annoying down arrow.
