Is it possible to evenly distribute buttons across the width of a LinearLayout

Question

I have a LinearLayout (oriented horizontally) that contains 3 buttons. I want the 3 buttons to have a fixed width and be evenly distributed across the width of the LinearLayout.

I can manage this by setting the gravity of the LinearLayout to center and then adjusting the padding of the buttons, but this works for a fixed width and won't work for different devices or orientations.

<LinearLayout     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:gravity="center"     android:orientation="horizontal">      <Button         android:id="@+id/btnOne"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:width="120dp" />      <Button         android:id="@+id/btnTwo"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:width="120dp" />       <Button         android:id="@+id/btnThree"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:width="120dp" /> </LinearLayout> 

Answer 1

Expanding on fedj's answer, if you set layout_width to 0dp and set the layout_weight for each of the buttons to 1, the available width will be shared equally between the buttons.
