Android HOME鍵那些事

app中對於HOME鍵廣播事件的接收
首先，自定義一個BroadcastReceiver：
    class HomeKeyEventBroadCastReceiver extends BroadcastReceiver {

        static final String SYSTEM_REASON = "reason";
        static final String SYSTEM_HOME_KEY = "homekey";//home key
        static final String SYSTEM_RECENT_APPS = "recentapps";//long home key
        
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            if (action.equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)) {
                String reason = intent.getStringExtra(SYSTEM_REASON);
                if (reason != null) {
                    if (reason.equals(SYSTEM_HOME_KEY)) {
                        // home key處理點
                        
                    } else if (reason.equals(SYSTEM_RECENT_APPS)) {
                        // long home key處理點
                    }
                }
            }
        }
    }

其次，生成且註冊之

        receiver = new HomeKeyEventBroadCastReceiver();
        registerReceiver(receiver, new IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS));
