Layout design for tablet

Question

I'm trying to design the layout for tablet. I want each control to have equal spaces between each other. How all of these can be aligned properly ? Sorry I cannot attach the image as I don't have 10 reputation :(. Please help

Here is the layout code and the parent layout is linear layout.

<RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="125dp"
    android:background="#517398"
    >

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="125dp"
        android:layout_marginBottom="8dp"
        android:layout_marginLeft="30dp"
        android:orientation="horizontal" >

        <ImageButton
            android:id="@+id/image_agenda"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_weight="1.0"
            android:src="@drawable/agenda_view" />
    </LinearLayout>

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="125dp"
        android:layout_centerHorizontal="true"
        android:orientation="horizontal" >

        <TextView
            android:layout_width="1dp"
            android:layout_height="fill_parent"
            android:layout_marginRight="40dp"
            android:background="#000000" />

        <ImageButton
            android:id="@+id/image_month"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1.0"
            android:src="@drawable/month_view" />

        <TextView
            android:layout_width="1dp"
            android:layout_height="fill_parent"
            android:layout_marginLeft="40dp"
            android:background="#000000" />
    </LinearLayout>

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="125dp"
        android:layout_alignParentRight="true"
        android:layout_marginRight="30dp"
        android:orientation="horizontal" >

        <ImageButton
            android:id="@+id/image_day"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:layout_weight="1.0"
            android:src="@drawable/day_view" />
    </LinearLayout>
</RelativeLayout>
