2 buttons side by side

Solution 1:

<LinearLayout 
    android:id="@+id/LinearLayout02" 
    android:layout_height="wrap_content" 
    android:layout_width="match_parent" 
    android:layout_alignParentBottom="true">
    <Button 
        android:id="@+id/Button02" 
        android:layout_width="match_parent" 
        android:layout_height="wrap_content" 
        android:layout_weight="1" android:text="Apply">
    </Button>
    <Button 
        android:id="@+id/Button03" 
        android:layout_width="match_parent" 
        android:layout_height="wrap_content"
        android:layout_weight="1" 
        android:text="Cancel">
    </Button>
</LinearLayout>

Solution 2:

If you want that the 2 buttons ocuppy all the width and the buttons have the same width, you must change in the 2 buttons the propertie:

android:layout_width="wrap_content" to android:layout_width="match_parent"

because if you have one of this button with a long text and the other button with short text, the button with long text ocuppy more space.
