Displaying text in left most position in Relative Layout

Question

'My Topic' text is displayed in centre at the top. And below that there is a list.
I want to display a '<Back' text at the left most position on the same line as 'My Topic'. How can i achieve this?

Here is the relevant layout XML:

 <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_margin="0dp"
            android:background="#FFFFFF"
            android:orientation="vertical"
            android:paddingLeft="0dp" >

            <TextView
                android:id="@+id/topic"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="center_horizontal"
                android:gravity="center_horizontal"
                android:text="My Topic"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:textStyle="bold"
                android:fontFamily="sans-serif" />

            <ListView
                android:id="@+id/list"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_below="@id/topic"
                android:layout_margin="0dp"
                android:paddingLeft="0dp" 
                android:divider="#A2B0B0"
                android:dividerHeight="0.5dp"               
                android:choiceMode="singleChoice" >
            </ListView>
        </RelativeLayout>

replace your layout with 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 and then give its reference to listview android:layout_below="@id/relTopic"
