Is this a LinearLayout with android:layout_weight attributes ?

Instead of using ScrollView as the main layout, use a LinearLayout but without the Button. For eg:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" 
        android:orientation="vertical">

        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="TextView" />

        <TextView
            android:id="@+id/textView3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="TextView" />

        <TextView
            android:id="@+id/textView2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="TextView" />

        <ExpandableListView
            android:id="@+id/expandableListView1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">
        </ExpandableListView>

    </LinearLayout>

Now in code, add the Button as the footerView of the ExpandableListView as :

final ExpandableListView elv = (ExpandableListView) findViewById(R.id.expandableListView1);
Button btn = new Button(this);
elv.addFooterView(btn); 

The button will always be present at the end of the ExpandableListView using this. Just as you want it to be.

You should place your expandable Listview and your button in a relative layout, and set align below is your button, It works for me.
