gesture

问题 I would like to use some of the more complex touch screen gestures that you can't access from Gdx.input I saw that to do this i must create a Gesture listener so i created the class GestureHandler and copied the code from the wiki. My gesture handler looks like this: public class GestureHandler implements GestureListener { @Override public boolean touchDown(float x, float y, int pointer, int button) { return false; } @Override public boolean tap(float x, float y, int count, int button) {

问题 I have attached a touchlistener and gesturelistener in my onCreate() method. When I double tap my title bar in portrait mode everything works fine. But when I rotate my screen to landscape mode, the double tap isn't detected anymore. However the Listeners are still being called. And when I rotate my screen back to portrait mode, the double tap works again. My Listeners: //Add double click gesture listener to Title Bar. final GestureDetector gestureDetector = new GestureDetector(this, new

问题 I would like to change the transform origin to the center point of the pinch gesture. This working code (safariDevSample) applies scale and rotation without changing the transform-origin : window.angle = 0; //global to store data for later reset .... var newAngle; window.scale = 1; var newScale; function saveChanges() { window.angle = newAngle; window.scale = newScale; } function getAngleAndScale(e) { // Don't zoom or rotate the whole screen e.preventDefault(); newAngle = window.angle + e

问题 I apologize for the newbie question : How do you implement the pinchzoom gesture in phonegap apps? I am just starting with PhoneGap and a little education wont hurt hehe ! Thnx! 回答1: My experience is that you don't implement it so much as you use it. Phonegap is essentially a webview (think mobile safari). So it does allow for automatic zooming gestures, but to implement it, you do so just as you would with any website (basically create web content that requires it, or utilize webkit calls

问题 I have ActivityMain which has inner class of OnSwipeTouchListener this class contains the logic for touch gestures. But I don't know how to implement swipe left and right within my onCreate function. I guess I would need to implement it on the View or this in referencing mainactivity. But I can't figure out how. If someone can point out how to call onSwipeRight and onSwipeLeft inside the onCreate method, appreciated. package org.pctechtips.zentech.TestApp; import android.content.Context;
