I have two android device with same resolution
Device1 -> resolution 480x800 diagonal screen size -> 4.7 inches
Device2 -> resolution 480x800 diagonal screen size -> 4.0 inches
How to find device diagonal screen size?
Detect 7 inch and 10 inch tablet programmatically
I have used the above link but it gives both device diagonal screen size -> 5.8
548
Screen size measurements for smartphones are calculated by measuring diagonally from the upper left-hand corner of the screen to the lower right-hand corner*. These measurements are expressed in inches.
You can get the device screen width via the screen. width property. Sometimes it's also useful to use window. innerWidth (not typically found on mobile devices) instead of screen width when dealing with desktop browsers where the window size is often less than the device screen size.
try this code to get screen size in inch
DisplayMetrics dm = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(dm); int width=dm.widthPixels; int height=dm.heightPixels; double wi=(double)width/(double)dm.xdpi; double hi=(double)height/(double)dm.ydpi; double x = Math.pow(wi,2); double y = Math.pow(hi,2); double screenInches = Math.sqrt(x+y); This won't work?
DisplayMetrics dm = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(dm); double x = Math.pow(dm.widthPixels / dm.xdpi, 2); double y = Math.pow(dm.heightPixels / dm.ydpi, 2); double screenInches = Math.sqrt(x + y); Log.d("debug", "Screen inches : " + screenInches); If you love us?
