activity_main.xml

<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">     <linearlayout         android:layout_width="match_parent"         android:layout_height="45sp"         android:id="@+id/llayout"         android:background="@drawable/navbar"         android:padding="3sp" >            <textview             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:layout_gravity="center_vertical|center_horizontal"             android:layout_weight="1"             android:gravity="center_horizontal"             android:text="golden stone"              android:textcolor="@color/white"             android:textsize="20sp" >         </textview>       </linearlayout>      <listview         android:id="@+id/mylist"         android:layout_width="match_parent"         android:layout_below="@id/llayout"         android:layout_height="match_parent" >     </listview>  </relativelayout> 

using listview in such case strange , unnecessary. think constraints (like: if items overflow?) , use proper layout manager. vertical linearlayout last item having non-zero layout weight.

listviews make sense if need abstraction generates list items on-the-fly.
