CheckBox not staying at bottom of dialog

Question

In my custom dialog, I am trying to get my checkbox to stay underneath my scrollview but it's not working. I've tried adding the checkbox under the scrollview in xml but it doesn't appear whenever I run the app. What needs to be done in order for the checkbox to remain at the bottom of the dialog (underneath the scrollview), and not be part of the scrollview when I scroll that? I don't want my checkbox to scroll with the scrollview at all.

java

LayoutInflater inflater = LayoutInflater.from(this);
View dialog_layout = inflater.inflate(R.layout.fragment_overlay, (ViewGroup) findViewById(R.id.Overlay_linearLayout));
AlertDialog.Builder db = new AlertDialog.Builder(this);
db.setView(dialog_layout);
db.setPositiveButton("OK", new DialogInterface.OnClickListener() {
});
db.show();

Try to set checkbox and ScrolView inside of new LinearLayout and put checkbox outside the ScrollView like this :

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <ScrollView android:id="@+id/Overlay_scrollView"
                xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="fill_parent"
                android:layout_height="0dp"
                android:layout_weight="1">

        <TableLayout android:id="@+id/Overlay_tableLayout"
                     xmlns:android="http://schemas.android.com/apk/res/android"
                     android:layout_width="fill_parent"
                     android:layout_height="wrap_content"
                     android:weightSum="1.0">

                <ImageView
                    android:layout_width="0px"
                    android:layout_height="80dp"
                    android:layout_weight="0.3"
                    android:src="@drawable/ic_launcher"/>

                <TextView
                    android:id="@+id/MapOverlay_textView0"
                    android:layout_width="0px"
                    android:layout_weight="0.7"
                    android:text="tion0"/>


                <ImageView
                    android:layout_width="0px"
                    android:layout_height="80dp"
                    android:layout_weight="0.3"
                    android:src="@drawable/ic_launcher"/>

                <TextView
                    android:id="@+id/MapOverlay_textView1"
                    android:layout_width="0px"
                    android:layout_weight="0.7"
                    android:text="dada"/>


                <ImageView
                    android:layout_width="0px"
                    android:layout_height="80dp"
                    android:layout_weight="0.3"
                    android:src="@drawable/ic_launcher"/>

                <TextView
                    android:id="@+id/MapOverlay_textView2"
                    android:layout_width="0px"
                    android:layout_weight="0.7"
                    android:text="ruction2"/>


                <ImageView
                    android:layout_width="0px"
                    android:layout_height="80dp"
                    android:layout_weight="0.3"
                    android:src="@drawable/ic_launcher"/>

                <TextView
                    android:id="@+id/MapOverlay_textView3"
                    style="@android:style/TextAppearance.Medium"
                    android:layout_width="0px"
                    android:layout_weight="0.7"
                    android:text="_instruction3"/>


        </TableLayout>
    </ScrollView>

    <CheckBox
        android:id="@+id/skip"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Don't show this again"/>
</LinearLayout>
