Set view width as the latger view of group

I have 3 views in vertical LineartLayout. I want to make width of each the same, bu开发者_运维百科t as small as the larger view can be.

Each view is a button, and have different text size. So if i set wrap_content, every button have different size. If i set fill_parent - every view is as large as screen.

So how can i do that without runtime code (only xml layout markup)?

Set all button's widths to fill_parent with the layout_weight="1" for each of them. Like

<Linearlayout ...>
    <Button android:layout_width="fill_parent"
    ........ 
    anddroid:layout_weight="1"/>

    <Button android:layout_width="fill_parent"
    ........ 
    anddroid:layout_weight="1"/>

    <Button android:layout_width="fill_parent"
    ........ 
    anddroid:layout_weight="1"/>

</LinearLayout> 

1. Setting weights

2. Set the absolute dimensions for the layout width and height of the view Eg: android:layout_width="30dip" android:layout_height="15dip"

3. Set the style attributes for the buttons: A Button can have a few style attributes that can be set on it:

   1. normal button – no style attributes required, this is the default
   2. normal right style – style=”?android:attr/buttonStyleRight”
   3. small style – style=”?android:attr/buttonStyleSmall”
   4. small right style – style=”?android:attr/buttonStyleSmallRight”

Any of the above three things can be done to achieve the desired result.
