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_height="0dp">

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.
