Android action bar with two stretched buttons

Question

Does anybody know how to easily implement an action bar with two stretched buttons?

Here is an example of the Google calendar app:

Answer 1

Make a horizontal LinearLayout with two buttons. Then set each of their widths to match_parent and android:layout_weight="0.5" (Each button will then take up 50% of the space).

EDIT:

To apply as the ActionBar background:

(ActionBarSherlock) getSupportActionBar().setCustomView(R.layout.my_view);
(ActionBar) getActionBar().setCustomView(R.layout.my_view);
