Change LinearLayout by screen dimensions

I am new to programming for Androids. I am seeking for any information about programming for Androids. Now I am wondering how to change -for example- buttons size considering of what is screen size.

As an example I have:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_gravity="center_vertical"
    android:baselineAligned="false"
    android:layout_marginLeft="40px"
    android:layout_marginRight="40px"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >
</LinearLayout>

And now I need this layout for a phone:

android:layout_marginLeft="40px"
android:layout_marginRight="40px"

but if there would be a tablet then I need 

android:layout_marginLeft="200px"
android:layout_marginRight="200px"

How could I achieve this?

Also if you have bookmarked good tutorials on how to handle orientation please share.

Thanks.

use dp instead of px for specifying margins and all.and try to use this in manifest file like this  <supports-screens
        android:anyDensity="true"
        android:largeScreens="true"
        android:normalScreens="true"
        android:resizeable="true"
        android:smallScreens="true"
         />

It is advisable not to use px, instead you should use dp i.e Density-independent Pixels. For orientation support you should declare separate layout xml.

I would suggest you to read up on "Supporting multiple screens" guide from android developers site and especially the section on "Declaring Tablet Layouts".
