中心对齐的线性布局的滚动视图在小型设备和横向模式下包装了顶部内容

Question

Scroll view of center aligned linear layout is wrapping top content in small resolution devices as well as landscape mode too.

but when i removed the center_vertical in linear lay out it is working fine, but i want that linear layout to be in center_vertical only.

Below is my code:!

<ScrollView
        android:id="@+id/bodyscrollview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:fillViewport="true" >

        <LinearLayout
            style="@style/app_update_alert_bg"
            android:layout_width="fill_parent"
            android:layout_height="0dp"
            android:layout_gravity="center_vertical"
            android:layout_marginBottom="5dp"
            android:orientation="vertical" >

            <TextView
                style="@style/app_update_alert_bg_text"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/updateinfo1" />

            <TextView
                style="@style/app_update_alert_bg_text"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/updateinfo2" />

            <ImageView
                style="@style/margin5dp"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center_horizontal"
                android:background="@drawable/switching_image_border"
                android:src="@drawable/switching_image_sb" />

            <ImageView
                style="@style/margin5dp"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center_horizontal"
                android:background="@drawable/switching_image_border"
                android:src="@drawable/switching_image_ucc" />

            <CheckBox
                android:id="@+id/chckbox_dontshow_again"
                style="@style/margin5dp"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:button="@drawable/custom_checkbox"
                android:text="@string/updateinfo_dontshow" />

            <Button
                android:id="@+id/btn_updatealert_confirmation"
                style="@style/buttonStyle.signInButton"
