</RelativeLayout>

My problem is that i looks fine in Google Nexus(H-533 ,W-320) calculated by

   Display display = getWindowManager().getDefaultDisplay();
    int screenHeight = display.getHeight();
    int screenWidth = display.getWidth();
    Log.i("Screen Height = ",Integer.toString(screenHeight) );
    Log.i("Screen Width = ",Integer.toString(screenWidth) );

and i have created different folders according to resolution,its taking xml from

layout-normal-mdpi

when i see this layout in HTC legend(H - 480 W-320) Or Samsung Ace the last three image buttons looking compressed about half of their height between normal button and Tabbar.The problem i guess in the small height with respect to Nexus, and all three devices are using same mdpi resolution xml file .So what should i do to make this layout work according to diff screen heights of same mdpi resolution devices.

If thats not possible from layout

weight

can i change button size programmatically after calculating screen size?

Thanks
