When the expandable listview has a long list of items, it expands over the bottom layout (the buttons layout).

Is there a way to tell the listview to expand up to where the bottom layout starts?

Best How To :

I have made some changes in your XML File.What I did is make your Button Layout android:layout_alignParentBottom="true" and make your details layout as android:layout_above="@+id/button_layout".Hope it will solve your issue.

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