Android responsive layout

I am building application (calculator). I use table layout with buttons inside. It looks perfect on screen of Samsung Galaxy II, however it looks very bad on bigger screens. The buttons hight is very small. How I can stretch the buttons on bigger screens?

The layout XML is bellow:

<ScrollView xmlns:android="http://schemas.an
    xmlns:tools="http://schemas.android.com/
    android:layout_width="match_parent"     
    android:layout_height="match_parent"    
    android:gravity="right"                 
    android:paddingBottom="@dimen/activity_v
    android:paddingLeft="@dimen/activity_hor
    android:paddingRight="@dimen/activity_ho
    android:paddingTop="@dimen/activity_vert
    tools:context=".MainActivity" >         


<TableLayout                                
    android:layout_width="match_parent"     
    android:layout_height="match_parent"    
    android:gravity="right"                 
    >                                       



    <TableRow                               
        android:id="@+id/tableRow1"         
        android:layout_width="match_parent" 
        android:layout_height="0dp">        

        <Button

            android:layout_width="0dp"      
            android:layout_weight="0.33"    
            android:layout_height="fill_pare

Over and all, you need to create different layouts/drawables for supporting all the screens. It depends on your requirement, say for example, if you would want to include 2 buttons in small screen and 4 buttons on large screens then obvious you have to create different layouts.

If you would want to display same number of buttons in all screens then I would suggest you to prepare different set of images/drawables and include them in your project. Here you don't need to do anything other than placing images in particular drawable folders.

One more thing, If its a plain background then you can create 9-patch image so that it can stretch with whatever size you want or your device supports.
