I want to achieve multi touch feature for whole screen means if user perform zoom in-zoom out using his finger then it should zoom in and zoom out whole screen(increase and decrease all buttons,text views size accordingly once). How to achieve it using android 2.1? regards, Piks 回答1: This might give you an idea: import java

问题 I've inherited an WPF application that targets Net 3.5, And I have to install it in a Surface Pro 4 (I5). The application is hanging in different points, and I have observed that animations sometimes never fire the completed event (maybe they end up at some point, but not at the time expressed in Duration property). As a turnaround, I tried Disable the RealTimeStylus for WPF Applications but after several trials, I noticed that although the DisableWPFTabletSupport method is executed and

问题 I've playing around with recognizing the touches in an iOS Application, and I have this simple code - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"%lu",(unsigned long)[touches count]); [touches enumerateObjectsUsingBlock:^(id obj, BOOL *stop) { UITouch *touch = obj; CGPoint touchLocation = [touch locationInNode:self.scene]; NSLog(@"B x:%f - y:%f",touchLocation.x,touchLocation.y); }]; } -(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { [touches

问题 I am trying to drag two objects simultaneously with multitouch in AS3. My goal is to have the user pinch the two objects together. Right now I cannot get both to be moving at the same time. Any ideas why this isn't working? Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT; // bullseye4a.addEventListener(TouchEvent.TOUCH_BEGIN, fl_ClickToDrag4a); function fl_ClickToDrag4a(event: TouchEvent): void { bullseye4a.startDrag(); } bullseye4b.addEventListener(TouchEvent.TOUCH_BEGIN, fl

问题 I have developed an Android application that is handling multitouch in a view. I basically track the several MotionEvents that can occur like ACTION_UP, ACTION_MOVE, ... My overwritten onTouch method in the View class looks like this: public boolean onTouch(View view, MotionEvent event) { int action = event.getAction() & MotionEvent.ACTION_MASK; if (action == MotionEvent.ACTION_DOWN) { float x = event.getX(); handleTouchStart(view, x); } else if (action == MotionEvent.ACTION_UP) { float x =

问题 I would like to know how to detect and differentiate between touches in a multi-touch view. I have read about a "hash" code, but I don't understand how to use it. I want to know when two of my Sprites are touched at the same time, like as if pressing a chord on two keys of a piano. [EDIT] Here is an example of what I have for my ccTouchesBegan: - (void) ccTouchesBegan:(NSSet*)touches withEvent:(UIEvent*)event { NSSet *allTouches = [event allTouches]; int validTouchCount = 0; for (UITouch*

问题 (For background, see Composing a WM_TOUCH message for SendMessage(), Kinect as a multi-touch device which asks basically the same question as mine but whose accepted answer doesn't actually answer the question. The tricky bit isn't filling in TOUCHINPUT structures but making a valid touch input handle.) I would like to simulate the presence of a multi-touch input device in a nasty hackish way, which in outline goes like this: while (true) { choose locations etc. for simulated touches;

问题 I am writing an custom ViewGroup where I need to use only single finger touch and wanted to remove multitouch completely. I have checked with other option android:splitMotionEvents="false" android:windowEnableSplitTouch="false" but both are not working. EDIT @Override public boolean onTouchEvent(MotionEvent ev) { DragHelper.processTouchEvent(ev); return true; } Any suggestion ! 回答1: Try following code in your custom view. @Override public boolean onTouchEvent(MotionEvent event) { // TODO Auto

问题 How do you implement a touch hash code and reference it later? I have read about a "hash" code, but I don't understand how to use it. I want to know when two of my Sprites are touched at the same time, like as if pressing a chord on two keys of a piano. Here is an example of what I have for my ccTouchesBegan: - (void) ccTouchesBegan:(NSSet*)touches withEvent:(UIEvent*)event { NSSet *allTouches = [event allTouches]; int validTouchCount = 0; for (UITouch* touch in allTouches) { BOOL
