Sorry, i've completed my question very much, so I reasked that and deleted prev post...
I'm using LinearLayout ( with 4 ImageButtons in a raw ) in a RelativeLayout in my project and I have used android:layout_alignParentBottom="true" for it ( linear ) to stick to the buttom of RelativeLayout, but my problem is the space between LinearLayout's ImageButtons and the corners of the screen. I want to remove them to make my ImageButtons be like a menu bar on the bottom of the screen. Is it possible for anyone to help me please ? THANK YOU ! :)

Remove the padding on your RelativeLAyout
From:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".HomeActivity">
To:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
