Custom layout of spinner in Android

I'm developing an Android application, I have to implement a custom layout for a spinner item.

I would realize a spinner like this:

I have a problem to implement the "gold arrow and border".

This is my code:

<Spinner
    android:id="@+id/spinner_language"
    android:layout_width="210dp"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:gravity="center_horizontal"
    android:entries="@array/spinnerItems"
    android:dropDownVerticalOffset="10dip"
    android:dropDownHorizontalOffset="0dip"/>

This is my spinner layout:

<CheckedTextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    style="?android:attr/spinnerDropDownItemStyle"
    android:singleLine="true"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textColor="@color/white"
    android:background="@color/custom_black"
    android:textSize="20dp"
    android:paddingTop="10dp"
    android:paddingBottom="10dp"/>

How i can realize it ?

I hope, this will help you..

1) In drawable folder--->add spinner_border.xml for border of spinner.

    <shape xmlns:android="http://schemas.android.com/apk/res/android">
     <solid android:color="@android:color/black" />
     <corners android:radius="0dp" />
     <stroke
      android:width="1dp"
      android:color="#B4925A" />

2)In layout design of spinner use this drop down "arrow_icon" for imageview src

     <RelativeLayout
                android:layout_width="210dp"
                android:layout_height="wrap_content"         
                android:background="@drawable/spinner_border"
                android:layout_gravity="center_horizontal"
                android:orientation="horizontal">

                <Spinner
                    android:id="@+id/spinner2"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_centerVertical="true"
                    android:layout_gravity="center"
                    android:background="@android:color/transparent"
                    android:gravity="center_horizontal"
                    android:entries="@array/spinnerItems"
                    android:spinnerMode="dropdown" />

                <ImageView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_alignParentRight="true"
                    android:layout_centerVertical="true"
                    android:layout_gravity="center"
                    android:src="@drawable/arrow_icon" />

            </RelativeLayout>

If there any further query,please inform, Thanks...
