问题 I am fairly new to android and am having some problems with a layout. Below is an approximation of what I want the layout to look like. (I would like the list to be below the screen at first so that the user can scroll down to see it.)

问题 Hi I am trying to print out level order of a binary search tree in the format (node element, parent node element) .

问题 I have a user control that is loaded into the parent window, and I want to raise a parent event when a button on the user control is clicked. How can I communicate with the parent through my user control in WPF? 回答1: First way that comes to mind is to have your UserControl raise an event that the parent window is listening to. The parent can then raise the event you want. 回答2: You're looking for Routed Events. The Click event on Button is a RoutedEvent, so if your UserControl has a button

问题 I have an activity which has a thread and a view in it...they're suspiciously similar to LunarLander.
