It is a common requirement to layout a bunch of buttons side by side. Making them of equal width is just plain good GUI design.
To achieve the effect above, first create a LinearLayout just for the buttons. The layout will contain three buttons.
<LinearLayout android_id="@+id/LinearLayout02" android_layout_height="wrap_content"
android_layout_width="fill_parent">
<Button android_layout_height="wrap_content" android_text="Update"
android_layout_width="fill_parent" android_layout_weight="1"/>
<Button android_layout_height="wrap_content" android_text="New"
android_layout_width="fill_parent" android_layout_weight="1"/>
<Button android_layout_height="wrap_content" android_text="Delete"
android_layout_width="fill_parent" android_layout_weight="1"/>
</LinearLayout>
We took these steps to get the effect:
1. For the LinearLayout we set android_layout_width="fill_parent". This causes the layout view to take up the full width available from the device.
2. For each Button, we set android_layout_width="fill_parent" and android_layout_weight="1".
