bounce

问题 I've been hunting around for an answer on here, Google, etc., and can't seem to quite nail this one. I have an image with an ID of #pin01. This is a pin on a map that I have animating down within a div, landing on an image of a map (think Google map). My JQuery, which works just great, is this: $('#pin01').animate({ opacity: 0}, 0).delay(500); $('#pin01').animate({ opacity: 1, top: "305px" }, 500); and my HTML is as follows: <img src="images/pin_blue.png" id="pin01" /> The animation works

问题 I have a ScrollView which has two hidden images, one at the top and one at the bottom. In between there is a bunch of visible content. What I need to do is make these images hidden by default but when you scroll all the way up or all the way down you could see them as you're scrolling. But then as soon as you stop scrolling it should bounce back to the visible area so that the hidden images aren't showing. Basically I'm trying to imitate the bounce scrolling feature of the iphone UIScrollView

问题 I want to use a bounce effect on a RecyclerView . A bounce effect whenever I overscroll the content... Does there exist a library or example for it? 回答1: I also couldn't find any library that supports the bounce effect for RecyclerView. Eventually I ended up implementing a new library by myself. Check out my library overscroll-bouncy-android. . It currently supports RecyclerView with LinearLayoutManager. I'm also working on ListView and ScrollView. To use my library: Step 1: dependencies {

问题 I am now using the latest version of PhoneGap (3.4) and iOS7.1 beta3, and i find the body (maybe call UI View element) have a bad property of bounce just like the pic below, and i want to disable it. I tried to search on the website, and i find only <preference name="DisallowOverscroll" value="false" /> works for me, BUT i find this preference make bounce disabled in all elements in my App, and i just want to disable the body`s bounce just like the pic below, and keep bounce in div elements.

问题 I am building an app with a stream of social content and am trying to get the behavior of how instagram does it's stream in app. So basically a top header that scrolls off the screen but bounces between that and the content. I can make the top header scroll off the screen and I can make the view not bounce but I want to use Pull to refresh and that ends up going above the "faux" nav bar UIView . I know that a normal Navbar will produce this but this one that scrolls off is a different story.

问题 I have this draggable ball when you drag and release, it is going the oposite way. How can I make this bounce from the walls? Also if it is supposed to travel 600px and it hit a wall after 200px, it should go for 400px more. http://jsfiddle.net/bepcmsgo/5/ let circle = document.getElementById("circle"); let pos1 = 0; let pos2 = 0; let pos3 = 0; let pos4 = 0; let mouseDown = false; let currentCircleTop = 0; let currentCircleLeft = 0; circle.addEventListener("mousedown", function(e){ mouseDown

问题 This code makes the ball bounce around the canvas: //advance the ball ball.advance(); //check if ball should bounce off canvas sides if (ball.getCenterX() + ball.getRadius() > canvas.getWidth()) ball.setDirectionX(LEFT); if (ball.getCenterX() - ball.getRadius() < 0) ball.setDirectionX(RIGHT); if (ball.getCenterY() + ball.getRadius() > canvas.getHeight()) ball.setDirectionY(UPWARDS); if (ball.getCenterY() - ball.getRadius() < 0) ball.setDirectionY(DOWNWARDS); Looks like this: https://gyazo.com

问题 I am using Swift Mailer to check for bounced messages. I have created one separate account for bounce messages, however when I set the return path, it does not allow the bounce message send to that account. Is it normal or is it a code error? $verp = 'bounces-' . str_replace('@', '=', $row['ReplyTo']) . '@gmail.com'; $message = Swift_Message::newInstance() ->setSubject($row['Subject']) ->setFrom(array($row['ReplyTo'] => $row['FromName'])) ->setReturnPath($verp) ->setBody($html, 'text/html') -

问题 I tried to programm a windmill with rotating rotor/head. The stem itself is fixed and drawn as a background onto a canvas (javafx). The rotor/head itself is another image. I thought I could rotate the image itself and draw it onto the graphicscontext. (Didn't work) Then I tried various things: a. Drawing the image onto another canvas, rotate the canvas, make a snapshot of that canvas. (Didn't work) b. Make an imageview, rotate the imageview, snapshot it and draw it (Didn't work) and c. I

问题 I am new to unity, and i am trying to create a bouncing ball, so i've did many researches about bouncing realted physics and i found a formula : Formula: -2*(V dot N)*N + V Where V is the velocity vector and N is the normal of the surface on which the ball will bounce Here is my script : using UnityEngine; using System.Collections; public class BallPhysics : MonoBehaviour { void Start () { rigidbody2D.velocity =new Vector2 (-1,-3); } // Update is called once per frame void Update () { } void
