[Android Q & A] How do I obtain the cell phone screen size?

This question is not complex, but there are a lot of people asking, so I should concentrate on answering it.

Starting from Android 3.2 (API Level 13), use the following method in the activity to obtain the screen size (in pixels ):

 
Display display = getwindowmanager (). getdefaultdisplay ();//Activity # getwindowmanager ()Point size =NewPoint (); display. getsize (size );IntWidth =Size. X;IntHeight = size. Y;
 

IfCodeInstead of writing in the activity, use the following method (obtain the Display object through window_service ):

Windowmanager WM =(Windowmanager) CTX. getsystemservice (context. window_service); display=WM. getdefadisplay display (); display. getsize (size );IntWidth =Size. X;IntHeight = size. Y;
 

If the Android version3.2 or lessBecause the Display object does not have the getsize () method, use the following method to obtain the screen size:

 
Display display =Getwindowmanager (). getdefaultdisplay ();IntWidth = display. getwidth ();IntHeight = display. getheight ();
 

Finally, the android system version and API level table are provided:
