Determine at runtime which layout was used

Question

I have a number of different layouts for different display sizes (see screen shot). Is it possible to determine programmatically, at runtime, which was used?

Edit: Suggestion was made to use this:

DisplayMetrics displayMetrics = new DisplayMetrics();
float density = displayMetrics.density;

This returns 0 for 3 devices: Samsung T530NU, ASUS Nexus 7, Droid Maxx
This code:

DisplayMetrics metrics = context.getResources().getDisplayMetrics();
int densityDpi = (int)(metrics.density * 160f);

returns the following:

Samsung T530NU: 160  
ASUS Nexus 7: 320  
Droid Maxx: 320

Edit 2: I implemented something simlar to @Selvin's suggestion:

Create these folders in res:

values-large-land  
values-med-land  
values-small-land  
values-xlarge-land  
values-large-port  
values-med-port  
values-small-port  
values-xlarge-port

Each folder contains a file called strings.xml
Each strings.xml contains a string called device_size:

<string name="device_size">small-land</string>

with the value changing with the folder. For the default strings.xml file in the values folder, I assign this:

<string name="device_size">unknown</string>

Then you can refer to the string:

String device_size = getResources().getString(R.string.device_size);

This returns:

Samsung T530NU: xlarge-land    
ASUS Nexus 7: large-land  
Droid Maxx: unknown

I'm not sure why the unknown on the Droid Maxx.

You can use `Configuration` to see what resources might qualify. You cannot directly determine what layout gets used, though, by any means that I can think of. — CommonsWare, Nov 17 '16 at 18:58
you may create coresponding values with fx string resources ... in `values-med-land/test.xml` with `med-land` ... and so on ... then you can get this value .... — Selvin, Nov 17 '16 at 19:12
@Selvin: That's a clever idea. I've implemented something like that now. Please post your suggestion as an answer. — Al Lelopath, Nov 17 '16 at 20:40

There is not any resource folder qualifier names as med !

You should use normal instead. For example :

values-normal-land
values-normal-port

for more information refer this link from google.

That works, but I don't get it: Why would I get an error with `values-xxlarge-land` folder but not `values-med-land` folder? – Al Lelopath Nov 21 '16 at 15:19
maybe med refer to a qualifier. locale name for example. that is why you do not see any error. @AlLelopath – Omid Heshmatinia Nov 22 '16 at 05:58
