Android: EditText NextFocusDown not trigger Spinner

In my application I have one registration screen, There are lot of EditTexts and Spinners. I want to go through the Registrations field one by one.

So I applied android:imeOptions="actionNext" . But It ignores all the Spinners. It will give focus only to EditText. I have also tried setNextFocusDownId(). This is also ignore the spinners.

   <LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/reportentry11"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <EditText
            android:id="@+id/numbers"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"

            android:imeOptions="actionNext"
            android:inputType="phone" 
            >
           <requestFocus/>
        </EditText>

        <LinearLayout
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:id="@+id/reportentry12"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal"
            >

            <TextView
                android:id="@+id/txt_exp"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"

                android:text="EXP:"
                android:textColor="#000000"
                android:textSize="12dp" />

            <Spinner
                android:id="@+id/spin_date"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:layout_weight="3"
                android:focusable="true"
                android:focusableInTouchMode="true"
                android:nextFocusDown="@+id/spin_year"
                android:text="date"
                android:textSize="12
