1. The two-segment code in method one should precede setcontentview ().

2, method Two can only hide the status bar and the title bar at the same time.

3, method One and method two are applied only to a single activity. Method three applies to the whole program.

For tablets running Android 4.0 or above, the above three methods do not hide the status bar below the screen and must be treated as follows.

public class Startupactivity extends activity{@Overrideprotected void OnCreate (Bundle savedinstancestate) { Super.oncreate (savedinstancestate); Setcontentview (r.layout.activity_startup); * * Hide the status bar below the screen of a tablet running Android 4.0 or above system          */try {String procid = "79"; if (Android.os.Build.VERSION.SDK_INT >= Android.os.Build.VERSION_CODES. Ice_cream_sandwich) ProcID = "42"; ICS//requires root privileges Process proc = Runtime.getruntime (). EXEC (new string[] {"Su", "-C", "Service call AC Tivity "+ procid +" S16 "});      was Proc.waitfor (); } catch (Exception ex) {Toast.maketext (Getapplicationcontext (), Ex.getmessage (), toast.length_long). Sh      ow ();      }} @Overrideprotected void OnDestroy () {//TODO auto-generated Method stub/* * Restores the status bar below the screen of the tablet that runs Android 4.0 above the system */try {Process proc = runtime.getruntime (). EXEC (new string[] {"AM", "StartService", "-N", "".          Systemuiservice "}); Proc. WaitFor ();      } catch (Exception e) {e.printstacktrace (); } Super.ondestroy ();} @Overridepublic boolean Oncreateoptionsmenu (Menu menu) {//Inflate the menu; This adds items to the action Bar if it is pre Sent.getmenuinflater (). Inflate (, menu); return true;} @Overridepublic boolean onoptionsitemselected (MenuItem Item) {//TODO auto-generated method Stubswitch (Item.getitemid ( ) {case (); return true;}}

Since the status bar is not available, you must provide a method for exiting the program in the program.
