01
class HomeKeyEventBroadCastReceiver extends BroadcastReceiver
 {

02
    static final String
 SYSTEM_REASON = "reason";

03
    static final String
 SYSTEM_HOME_KEY = "homekey";//
 home key

04
    static final String
 SYSTEM_RECENT_APPS = "recentapps";//
 long home key

05
 
06
    @Override

07
    public void onReceive(Context
 context, Intent intent) {

08
        String
 action = intent.getAction();

09
        if (action.equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS))
 {

10
            String
 reason = intent.getStringExtra(SYSTEM_REASON);

11
            if (reason
 != null)
 {

12
                if (reason.equals(SYSTEM_HOME_KEY))
 {

13
                    //
 home key处理点

14
                    Log.d(TAG, "HOME
 CLICK!!!!!!!");

15
                } else if (reason.equals(SYSTEM_RECENT_APPS))
 {

16
                    //
 long home key处理点

17
                    Log.d(TAG, "HOME
 LOND CLICK!!!!!!!");

18
                }

19
            }

20
        }

21
    }

22
}

在Activity onCreate中添加：
HomeKeyEventBroadCastReceiver mReceiver = new HomeKeyEventBroadCastReceiver();
registerReceiver(receiver, new IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS));

并在Activity onDestory中添加：
unregisterReceiver(mReceiver);
