Im trying to place two buttons on the xml next to each other and I want them both to be the same size(half from the width of the screen) - this is my xml:

<LinearLayout
        android:layout_width="fill_parent"
        android:orientation="horizontal"
        android:id="@+id/linearLayout2"
        android:layout_height="fill_parent"
        android:gravity="bottom"
        android:weightSum="2">
    <Button
        android:layout_weight="1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/bAddDelete"
        />

    <Button
        android:layout_weight="1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/bMainMenu"
         />
</LinearLayout>

Everything works well, but when im changing the text in java, the width is changing, how can I make them the same size?

Thanks
