app中对HOME键广播事件的接收

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处理点  
                      
                } else if (reason.equals(SYSTEM_RECENT_APPS)) {  
                    // recent apps key处理点  
                }  
            }  
        }  
    }  
}  
           

然后，只要注册广播事件

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

这样，我们就可以在app中进行HOME键的处理了！
