How to add a Hibernate feature to the Android Tablet power button Menu

1. Modify/frameworks/base/core/res/res/values/strings.xml

Declare several variables here:

<!--New screen-sleeping item-->

<string name= "Global_action_sleep" >Sleep</string>

<!--add a sleep string-->

<string name= "Sleep" >Sleep</string>

<!--new Confirmation screen hibernate information-->

<string name= "sleep_confirm" >the machine screen would turn off.</string>

2. Modify/frameworks/base/core/java/com/android/internal/app/shutdownthread.java

To refer to a few packages

Import Android.os.SystemClock;  
Android.os.PowerManager; Add screen standby method public static void Gotosleep (context Context,long time) {context.enforcecallingorselfpermission Droid.  
      Manifest.permission.DEVICE_POWER, NULL); Final Alertdialog Dialog = new Alertdialog.builder (context). SetIcon (Android. R.drawable.ic_dialog_alert). Settitle (Com.android.internal.r.string.sleep). Setmessage (Com.android.interna  
                                   l.r.string.sleep_confirm). Setpositivebutton (Com.android.internal.r.string.yes,  
                                           New Dialoginterface.onclicklistener () {public void OnClick (dialoginterface dialog, int which) {PowerManager pm = (powermanager) mcontext.getsystemservice (context.power_ser  
                                           VICE);  
                               Pm.gotosleep (Systemclock.uptimemillis ());        }). Setnegativebutton (com.android.internal.r.string.no, NULL)  
      . Create ();  
        Dialog.getwindow (). SetType (WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG);  
        Dialog.getwindow (). Addflags (WindowManager.LayoutParams.FLAG_BLUR_BEHIND);  
           
      Dialog.show (); }

3. Modify/frameworks/policies/base/mid/com/android/internal/policy/impl/globalactions.java

Find Mitems = lists.newarraylist, the original code defines two singlepressaction, that is, the Power button menu item, then in the inside

Add a Singlepressaction button that implements the screen hibernate function, imitating the original code

New Singlepressaction (Com.android.internal.r.drawable.ic_lock_power_off,  
                        r.string.global_action_sleep) { Public  
                       
                 void Onpress () {  
                  shutdownthread.gotosleep (Mcontext,systemclock.uptimemillis ());  
                        
                 }  
                       
                 public Boolean Showduringkeyguard () {return  
                  true;  
                 }  
                       
                 public Boolean showbeforeprovisioning () {return  
                  true;  
                 }  
                       
                }

After the revision, the patient waits, in the Android-x86 platform's tablet computer test can realize the computer the hibernation function
