touch-event

Hi i'm building a webapp. To remove the onclick delay i found this script on http://cubiq.org/remove-onclick-delay-on-webkit-for-iphone The code is bascically- function NoClickDelay(el) { this.element = el; if( 'ontouchstart' in window ){ console.log("===================touch supported :P") this.element.addEventListener('touchstart', this.handleEvent, false); } } NoClickDelay.prototype = { handleEvent: function(e) { switch(e.type) { case 'touchstart': this.onTouchStart(e); break; case 'touchmove': this.onTouchMove(e); break; case 'touchend': this.onTouchEnd(e); break; } }, onTouchStart:

Recently I am experiencing some issues with my scrollview. Touch events don't reach elements inside a scrollview after a fling has happened. After a fling has occurred I first need to tap the view once again, after that the normal behaviour is restored. I already tried lot's of workarounds like: Manually fire a motion event (up / down) after the fling. This works but has some serious issues, I don't have to explain why I guess since this is just the same as touching the view again but that at a certain x+y. Intercept touch events and always pass them to the underlying views. But all this is

I want to build a tool on Android where the user can paint some simple objects over a picture (eg line, circle or arrow). I started trying the line part first, and indeed I could succeed on painting it. The logic is that the user taps at one point and then drags their finger, painting the line. I use a class like this (it is based on DonGru's answer here ): public class DrawView extends View { Paint paint = new Paint(); float Sx, Sy, Lx, Ly; public DrawView(Context context, float x1, float y1, float x2, float y2) { super(context); paint.setColor(Color.RED); Sx=x1; Sy=y1; Lx=x2; Ly=y2; }

So, I am trying to check multiple screen touches with an onTouchEvent, but it still only seems to read the first touch. Can anyone help? Here is my code: public boolean onTouchEvent(MotionEvent e) { int num = e.getPointerCount(); for(int a = 0;a<num;a++) { int x = (int) e.getX(e.getPointerId(a)); int y = (int) e.getY(e.getPointerId(a)); check(x,y); } return false; } I looked over a lot of these forums, but most of the multi touch related topics were about zooming. Your code works well on my device (Nexus S, Android 2.3). It reads all touches. Here is the test code: public boolean onTouchEvent
