Question

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.

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