        android:background="#636260"

        android:horizontalSpacing="1dp"

        android:verticalSpacing="1dp" >

    </ListView>

    <Button

        android:id="@+id/kilBtn"

        android:layout_width="wrap_content"

        android:layout_alignParentBottom="true"

        android:layout_alignParentLeft="true"

        android:layout_alignParentRight="true"

        android:text="KillAllRunningApps" />

</RelativeLayout>

customadapter.xml

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

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

</RelativeLayout>

following permission add in manifest

<uses-permission android:name="android.permission.KILL_BACKGROUND_PROCESSES"/>

    <uses-permission android:name="android.permission.GET_TASKS"/>
