Align Button to Bottom using LinearLayout

Question

Trying to align button at Bottom using LinearLayout, but getting just below TextView.

To set button at bottom, I am using android:layout_gravity="bottom" but still not done

LinearLayout xml

    <LinearLayout
        android:id="@+id/linearLayout2"
        android:layout_width="0dp"
        android:layout_height="match_parent"            
        android:orientation="vertical" >

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal" >

        <TextView
            android:layout_width="0dp"
            android:layout_weight="1"
            android:layout_height="wrap_content"/>

        <TextView
            android:layout_width="0dp"
            android:layout_weight="1"
            android:layout_height="wrap_content"/>

        </LinearLayout>

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_gravity="bottom"
            android:layout_height="wrap_content">

            <Button
                android:layout_width="0dp"
                android:layout_weight="1"
                android:layout_height="wrap_content"
                android:text="Bottom" />

 </LinearLayout>

Answer 1

Change second linear layout to

<LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="0dp"
            android:layout_weight="1"
            android:orientation="horizontal" >

This will put the button at the bottom and this layout will take the rest of the space

Yoy have to use like this....

<RelativeLayout
        android:id="@+id/footer"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:gravity="center">
        <Button
                android:layout_width="0dp"
                android:layout_weight="1"
                android:layout_height="wrap_content"
                android:text="Bottom" />
    </RelativeLayout>
