I am having trouble with android layouts, I want to make app that will support multiple screens, tablets included.
But I am having problem with button sizes.

How do I set pictures to fit multiple screen sizes?
I have pictures in ressources for Xdpi Mdpi ldpi, but it seems that eclipse is not using them.
Regards

My button looks like this:

```
 <ImageButton
            android:id="@+id/sound4"
            android:layout_width="160dp"
            android:layout_height="81dp"
            android:layout_alignLeft="@+id/sound2"
            android:layout_alignParentRight="true"
            android:layout_alignTop="@+id/sound3"
            android:background="@drawable/famas"
            android:onClick="onClick" />

```
