问题 I tried to understand how Android handle touch event and got a little bit confused. From what I understand touch event are send to the root view and pass down to the children.

问题 After many experiments with onTouchEvent and onTouch, I found that onTouch works everywhere you want (whether it is in activity or view) as long as you have declared the interface and put the Listener right! On the other hand, onTouchEvent only works inside a View! Is my assumption correct? Is this the real difference? 回答1: Yes you are correct - onTouch() is used by users of the View to get touch events while onTouchEvent() is used by derived classes of the View to get touch events. 回答2: I

问题 I need to create a image wherever the user touched on the screen. If the user touches more places, the image should be shown in all the places.

问题 I have a slider that I built that changes the width of it to slide the element into view. On a desktop there are buttons to do this. I want to be able to make the slider work with a touch and drag event and for it to be smooth like iosslider. I have found a way that works but it is choppy and does not always respond. My code... <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" ></script> <script type="text/javascript">$(document).bind("mobileinit", function(){$

问题 I'm trying to create a view programmatically, and change its background according to its click state. I know I can do this with xml drawables, but I want to learn to program it too.

问题 I'm very new to Android programming, and trying to understand touch events with nested views. To start, here's a description of my app: I have a relative layout that I've added via the GUI editor. Everything is default. I've also created a class called ClipGrid that extends ScrollView. Nested inside that, I make a HorizontalScrollView. Inside of that, I make a TableLayout and it's rows. The rows contain buttons. The end result is a grid of buttons. It displays 4x4 at once, but can scroll
