A button next to an EditText

I have a Layout with an EditText that I can enter text into to search for a Location.

Here is my code:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:descendantFocusability="beforeDescendants"
    android:focusableInTouchMode="true"
    android:padding="5dip">
    <FrameLayout
        android:id="@+id/mapWithOverlay"
        android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:background="#ffffff"
        android:layout_below="@+id/thumbnail" />
    <ListView
        android:id="@+id/List"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_marginTop="50dp"
        android:layout_marginBottom="50dp" />
    <EditText
        android:id="@+id/inputSearch"
        android:layout_width="fill_parent"
        android:layout_height="50dp"
        android:hint="Find..."
        android:layout_alignParentTop="true" />
</RelativeLayout>

I am needing a button next to the EditText that I can click on to clear the ListView that is displayed.

How would be the best way to do this?

Thanks in advance
