i would like to have three buttons taking equal amount of available space horizontally in a row. I used android:layout_gravity. What is the problem?

layout xml :

<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:weightSum="1.0"
    >

    <Button android:id="@+id/button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/Bg"
            android:background="@drawable/button_red"
            android:layout_weight=".2"
            android:layout_gravity="left"
    />
    <Button android:id="@+id/button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/Bm"
            android:background="@drawable/button_red"
            android:layout_weight=".2"
            android:textColor="#ffffff"
            android:layout_gravity="center"
    />

    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/button_red"
        android:layout_weight=".2"
        android:text="@string/Bf"
        android:layout_gravity="right"
    />

</LinearLayout>

You can divide it like this: `

            <RelativeLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentLeft="true"
                android:layout_alignParentStart="true"
                android:layout_centerVertical="true"
                android:layout_toLeftOf="@+id/imageButtonLikedPost">

                <ImageButton
                    android:id="@+id/imageButtonMyPost"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_centerHorizontal="true"
                    android:layout_centerVertical="true"
                    android:background="@drawable/mypost_tab_bg" />
            </RelativeLayout>

            <ImageButton
                android:id="@+id/imageButtonLikedPost"
                android:layout_width="40dp"
                android:layout_height="30dp"
                android:layout_centerHorizontal="true"
                android:layout_centerVertical="true"
                android:background="@drawable/mylike_tab_bg" />

            <RelativeLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentEnd="true"
                android:layout_alignParentRight="true"
                android:layout_centerVertical="true"
                android:layout_toRightOf="@+id/imageButtonLikedPost">

                <ImageButton
                    android:id="@+id/imageButtonMyBlog"
                    android:layout_width="30dp"
                    android:layout_height="30dp"
                    android:layout_centerHorizontal="true"
                    android:layout_centerVertical="true"
                    android:background="@drawable/tab4_bg" />
            </RelativeLayout>
        </RelativeLayout>`
