Multiple button presses for Android 2.x

由 南楼画角 提交于 2019-11-27 09:48:19
I am relatively new to this still, and I have been developing a small app that would benefit greatly from a user being able to press 2 buttons at one time. What is the best method for achieving this? I dont think that an OnClickListener works like that, and I have seen examples for doing this with an OnTouch event. However, I do not know how to set up button presses with an OnTouch event. You would have to handle touch events yourself. With the multi-pointers (aka multi-touch) API it's very easy. Just override the onTouchEvent() method or register an OnTouchListener on your buttons. @Override

Multi-touch gesture in Sprite Kit

由 我的梦境 提交于 2019-11-27 09:31:45
I'm working in Swift with Sprite-Kit using XCode 6, and I have many different nodes but for the moment I only manage to detect one finger and move one node at the same time. I want to know how could I manage to detect multiple fingers in order to move multiple nodes at the same time. My actual code is : var location = CGFloat() // finger position var actualNode = -1 // node touched by the finger, -1 means no node touched override func touchesBegan(touches: NSSet, withEvent event: UIEvent) // when a finger touch the screen { for touch: AnyObject in touches { location = touch.locationInNode(self

How to disable multitouch?

由 喜欢而已 提交于 2019-11-27 07:25:18
My app has several buttons which trigger different events. The user should NOT be able to hold down several buttons. Anyhow, holding down several buttons crashes the app. And so, I'm trying to disable multi-touch in my app. I've unchecked 'Multiple Touch' in all the xib files, and as far as I can work out, the properties 'multipleTouchEnabled' and 'exclusiveTouch' control whether the view uses multitouch. So in my applicationDidFinishLaunching I've put this: self.mainViewController.view.multipleTouchEnabled=NO; self.mainViewController.view.exclusiveTouch =YES; And in each of my view
