How to place three buttons for viewing images on one line in Android

I have three imageViews . Here I want to install all of these ImageViewon one line. I pasted my current xml code below.

    <RelativeLayout
        android:id="@+id/myFragement"
        android:layout_width="wrap_content"
        android:layout_height="306dp"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="44dp"
        android:layout_weight="1.77"
        android:orientation="horizontal" >
    </RelativeLayout>

     <ImageView
         android:id="@+id/login_button"
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:layout_alignParentLeft="true"
         android:layout_alignParentTop="true"
         android:src="@drawable/login_non_click" />

    <ImageView
        android:id="@+id/comapre_now_button"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:src="@drawable/compare_now_non_click_state" />

    <ImageView
        android:id="@+id/search_button"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/comapre_now_button"
        android:src="@drawable/search_non_click" />

</RelativeLayout>

    android:layout_height="306dp"
    android:layout_alignParentRight="true"
    android:layout_alignParentTop="true"
    android:layout_marginTop="44dp"
    android:layout_weight="1.77"
    android:orientation="horizontal" >

</RelativeLayout>

 <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        android:orientation="horizontal"
        android:weightSum="3" >
     <ImageView
             android:id="@+id/login_button"
                  android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"

             android:src="@drawable/login_non_click" />

        <ImageView
            android:id="@+id/comapre_now_button"
             android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
            android:src="@drawable/compare_now_non_click_state" />

        <ImageView
            android:id="@+id/search_button"

        android:layout_height="wrap_content"
