}

首先来看DragArguments对象。该类为Drag中的私有类,它的构造方法回去解析传入的command,然后获得并存储一些drag方法用到的参数。例如拖拽控件时,被拖拽的控件对象,拖拽到的控件对象。坐标拖拽时,起始点坐标、终点坐标、步骤。所以就把它看成一个实体类就行了。然后分控件和坐标分别调用dragElement()和drag()方法。

dragElement()

如果拖拽到的控件不存在,那么就要用到结束坐标。如果拖拽到的控件存在,那么就用该控件计算拖拽到坐标,调用UiObject.dragTo()方法来执行命令。

drag()

直接调用UiObject.dragTo来执行
