A rendering of the two center buttons

Here is how to center 2 buttons inside a layout. These do not have to be buttons but can be any type of view. The idea behind it is to create a layout and add two horizontal Linear Layout inside and assign the same weight to both.  When the buttons are inside then center the buttons inside the layout. Since each layout is set to ‘match_parent’ then it will scale to any screen size.

Here  is the idea of centering two views inside a layout:

General idea of the concept (excuse the horrible drawing).

Here is the code:

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

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:layout_weight="1" >

            <Button
                android:id="@+id/cancel"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center_horizontal"
                android:layout_marginBottom="18dp" />

        </LinearLayout>

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:orientation="vertical"
            android:layout_weight="1" >

            <Button
                android:id="@+id/continue"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center_horizontal"/>

        </LinearLayout>

    </LinearLayout>
