Android – align the underlined spinners in the same line next to the edit text

I have an EditText and an underlined spinner. I try to set the spinner next to EditText on the same line. Please help me. Spinner is always slightly higher than EditText

 <RelativeLayout
        android:id="@+id/relativeLayout4"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/relativeLayout0"

        android:layout_alignParentLeft="true"
        android:layout_marginLeft="20dp"
        android:layout_marginRight="20dp">

        <ImageView
            android:id="@+id/ivRupee"
            android:src="@drawable/ic_rupee_new"
            android:layout_width="20dp"
            android:layout_height="20dp"
            android:layout_centerVertical="true"  />
        <ImageView
            android:id="@+id/fake"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"/>


        <EditText
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerVertical="true"
            android:id="@+id/editText"
            android:layout_toRightOf="@+id/ivRupee"
            android:layout_alignRight="@+id/fake"
            android:layout_marginRight="5dp"/>
        <Spinner

            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignBaseline="@+id/editText"
            android:gravity="center"
            android:layout_alignLeft="@+id/fake"
            android:layout_alignParentRight="true"
            android:id="@+id/spinner2"
            style="@style/Widget.AppCompat.Spinner.Underlined"/>

    </RelativeLayout>

I need something like this:

I encountered the same problem. I solved this problem by deleting style = "@ style / widget. Appcompat. Spinner. Understood" and set a background for spinner: Android = background = "@ drawable / custom_spinner_background"

custom_ spinner_ background.xml：
