Stage.addTouchFocus介绍

[英]Adds the listener to be notified for all touchDragged and touchUp events for the specified pointer and button. Touch focus is added automatically when true is returned from InputListener#touchDown(InputEvent,float,float,int,int). The specified actors will be used as the Event#getListenerActor() and Event#getTarget() for the touchDragged and touchUp events.
[中]添加要为指定指针和按钮的所有触碰和触碰事件通知的侦听器。当InputListener#触地（InputEvent、float、float、int、int）返回true时，触摸焦点会自动添加。指定的参与者将用作TouchDrawed和touchUp事件的事件#GetListGenerator（）和事件#getTarget（）。
