android 监听Home键和亮灭屏

1.注册广播

        IntentFilter filter = new IntentFilter();        filter.addAction(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);//home键        //filter.addAction(Intent.ACTION_USER_PRESENT);//用户解锁广播        filter.addAction(Intent.ACTION_SCREEN_OFF);//灭屏广播，亮屏为on        registerReceiver(mReceiver, filter);

2.接受广播

    private static final String SYSTEM_DIALOG_REASON_KEY = "reason";    private static final String SYSTEM_DIALOG_REASON_HOME_KEY = "homekey";    BroadcastReceiver mReceiver = new BroadcastReceiver() {        @Override        public void onReceive(Context arg0, Intent intent) {            String action = intent.getAction();            if(Util.EXIT_ACTION.equals(action)){                mTabHost.setCurrentTab(0);                mRadio_mylock.setChecked(true);            }else if(Intent.ACTION_CLOSE_SYSTEM_DIALOGS.equals(action)){                String reason = intent.getStringExtra(SYSTEM_DIALOG_REASON_KEY);                if (SYSTEM_DIALOG_REASON_HOME_KEY.equals(reason)) {                    // 短按Home键                }            }else if(Intent.ACTION_SCREEN_OFF.equals(action)){                  //灭屏             }        }    };
