This is my Design of campaign_create.xml

enter image description here

Spinner : 

        <com.weiwangcn.betterspinner.library.material.MaterialBetterSpinner
            android:id="@+id/select_city"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="Select Category"
            android:background="@drawable/rounded_white"
            android:textColorHint="#ffffff"
            android:layout_marginRight="10dp"
            android:layout_marginLeft="10dp"
            android:layout_alignParentStart="true"
            android:layout_marginTop="9dp" />

@drawable/rounded_white.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
    <shape>
        <solid android:color="#f2f2f2"/>
        <stroke android:width="0.1dp"
            android:color="@color/white"/>
        <corners android:radius="40dp"/>
    </shape>
</item>
</selector>

I want to set background of spinner.

It is drawable file. i set property 

android:background="@drawable/rounded_white"

but it didn't work.

It must be working, but you won't be able to check in preview.

Try setting values(Adapter) to spinner and run the code.

But as per your layout I guess you should take Linear or Relative Layout as parent and keeping Imageview and Spinner inside.

create a style for spinner like this :

  <style name="spinner_style" parent="Base.Widget.AppCompat.Spinner">
            <item name="android:background">@drawable/spinner_custom</item>
            <item name="android:layout_marginLeft">10dp</item>
            <item name="android:layout_marginRight">10dp</item>
            <item name="android:layout_marginBottom">10dp</item>
            <item name="android:paddingLeft">8dp</item>
            <item name="android:paddingTop">5dp</item>
            <item name="android:paddingBottom">5dp</item>
            <item name="android:popupBackground">#848484</item>
            <item  name="android:textColor">#000000</item>
        </style>

add this style in your spinner :

<Spinner
    style="@style/spinner_style"
    android:layout_width="match_parent"
    android:layout_height="40dp"
    android:layout_margin="5dp" />
