Project used, record, return key what the physical keys use onkeydown monitoring can be, but lock screen key, home button can not, here use Broadcast monitor both state changes

Intentfilter Fragment:

Mfilter.addaction (intent.action_close_system_dialogs);//home key            mfilter.addaction (intent.action_screen_on);  Open screen            mfilter.addaction (intent.action_screen_off);//Lock Screen            mfilter.addaction (intent.action_user_present);// Unlock

Onrecevier Fragment:

 public void OnReceive (context context, Intent Intent) {String action = intent.getaction (); if (Action.equals (intent.action_close_system_dialogs)) {String reason = Intent.getstringextra (system_dial                 Og_reason_key); if (reason! = null) {if (Mlistener! = null) {if (Reason.equals (system_dialog                         _reason_home_key)) {//short press the HOME key mlistener.onhomepressed ();                             } else if (reason.
