android - Determine at runtime which layout was used -

i have number of different layouts different display sizes (see screen shot). possible determine programmatically, @ runtime, used?

edit: suggestion made use this:

displaymetrics displaymetrics = new displaymetrics(); float density = displaymetrics.density; 

this returns 0 3 devices: samsung t530nu, asus nexus 7, droid maxx
code:

displaymetrics metrics = context.getresources().getdisplaymetrics(); int densitydpi = (int)(metrics.density * 160f); 

returns following:

samsung t530nu: 160   asus nexus 7: 320   droid maxx: 320  

edit 2: implemented simlar @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 file called strings.xml
each strings.xml contains string called device_size:

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

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

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

then can refer 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 unknown on droid maxx.

there not resource folder qualifier names med !

you should use normal instead. example :

values-normal-land values-normal-port 

for more information refer link google.
