XML layout with problems

I'm having a problem, I have a layout with some Text edit fields, what happens is that the Scrollview I use works for all of the Activity fields except for the button that ends up going down the screen. Does anyone have a good idea of what I can do? OBG desd already.

<?xml version="1.0" encoding="utf-8"?>

android:orientation="vertical">

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        >

        <LinearLayout
            android:id="@+id/fields_container"

            android:layout_marginLeft="20dp"
            android:layout_marginRight="20dp"
