Single Layout for all screen sizes
<p>I have read many documentation on supporting multiple screen sizes but still confused.
I have read like if specified in dp it will get automatically scaled.</p>

<p>In my sample i just have a single layout. there i have placed an edit text.
and given width , suppose 170 dp. suppose width wise it is half the screen in a 5 inch phone emulator.</p>

<p>What i was expecting is, if i show it on an tablet 7inch or 10 inch , there also it will be half the width of the screen (i.e it will get automatically scaled). But it didnt.  in a 10 inch tablet it  is only very small size.</p>

<p>what should i do to achieve this only  through layout xml ( only single xml )</p>
