android - text and sp / dp, it just does not work nicely -

-

i testing app on nexus 5 (full hd screen) , htc 1 x (720p).

using sp android developer, gives me result not want! text on nexus 5 bigger on htc 1 x, taking account screen bigger in size.

when use 'dp' instead of 'sp', more alike...the result want...

but want use sp, way should it.

so created values-sw380dp directory , put there different value. but, nexus 5 not use these values! used code:

displaymetrics displaymetrics = getresources().getdisplaymetrics();  float dpheight = displaymetrics.heightpixels / displaymetrics.density; float dpwidth = displaymetrics.widthpixels / displaymetrics.density;

surprisingly: both phones, dpwidth == 360! have no way nicely 720p , 1080p screen ?

does have idea or solution?

i tempted use dp...
