replace layout this

    <relativelayout     android:layout_width="match_parent"     android:layout_height="match_parent"     android:layout_margin="0dp"     android:background="#ffffff"     android:orientation="vertical"     android:paddingleft="0dp" >      <relativelayout android:id="@+id/reltopic"         android:layout_width="match_parent"         android:layout_height="wrap_content">      <textview         android:id="@+id/topic"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="center_horizontal"         android:layout_centerhorizontal="true"         android:text="my topic"         android:textappearance="?android:attr/textappearancemedium"         android:textstyle="bold"         android:fontfamily="sans-serif" />          <textview             android:id="@+id/back"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_gravity="center_horizontal"             android:layout_alignparentleft="true"             android:text="back"             android:textappearance="?android:attr/textappearancemedium"             android:textstyle="bold"             android:fontfamily="sans-serif" />     </relativelayout>      <listview         android:id="@+id/list"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_below="@id/reltopic"         android:layout_margin="0dp"         android:paddingleft="0dp"         android:divider="#a2b0b0"         android:dividerheight="0.5dp"         android:choicemode="singlechoice" >     </listview> </relativelayout> 

you can take both textview in single layout , give reference listview android:layout_below="@id/reltopic"
