<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:orientation="horizontal" >  <include layout="@layout/activity_main"/> <view     android:layout_width="1dp"     android:layout_height="fill_parent"     android:background="#a3a3a3"/>  <include layout="@layout/contact_details"/>  </linearlayout>
