transitions

问题 I have an item in which has two states, best described as open and closed, and they look like this: and And what I'd like to do is is smooth the transition between one state and the other, effectively by interpolating between the two points in a smooth manner (sine) to move the footer/button-block and then fade in the pie chart. However this is apparently beyond me and after wrestling with my inability to do so for an hour+ I'm posting it here :D So my transition block looks as follows <s

问题 If I try to store the following enter selection, I get an error when I try to access it. I don't have a problem if I remove the transition. Why? Are there other restrictions on storing selections? Here is an example: // this works var enterSel = d3.select("svg") .selectAll("circle") .data([100, 200, 300]) .enter() .append("circle") .attr("cx", d => d) .attr("cy", "100") .attr("fill", "red") .attr("r", "0") .transition() .duration(2000) .attr("r", "50"); The above appends and transitions three

问题 My app has a main view with some hidden elements that can be activated by the user. Like a typical sidebar on mobiles that slides in from the left. Or a cart that reveals the details when you tap on it. The information in those initially hidden elements is always up to date since their content is mapped in the main app template. So my routes would not need to render any DOM. The transitions are JS based. But now I want those states to be reflected in the URL, in order to get a consistent back

问题 I am playing around with Lollipop sceneTransitionAnimations . To get it to work you need to implement getWindow().setExitTransition() + getWindow().setReenterTransition() in the calling activity's onCreate , and getWindow().setEnterTransition() + getWindow().setReenterTransition() in the called activity's onCreate . Then, when you call startActivity you have to pass a Bundle to that function that you obtain by calling ActivityOptions.makeSceneTransitionAnimation(getActivity()).toBundle() .

问题 I am creating a transition. And when a button is clicked the following method is executed. The method changed the size , position of the image view, and it fades it out. I am using TransitionManager.beginDelayedTransition(); is too fast. to slow down the transition.. but it is still going too fast. What can i do to slow down the transition. Thank You. private void moveIcon() { View moveableIcon = findViewById(R.id.moveableImageView); TransitionManager.beginDelayedTransition(myLayout); //

问题 Can someone provide an example of how to progressively blur a SKSpriteNode's image using Apple's Sprite Kit? For instance, let's say the user touches a button on the screen which will then trigger the background to slowly (i.e. progressively) blur until it reaches a specific threshold. Ideally, I would like to reverse the process too (e.g. allow the user to unblur the image by touching the same button). 回答1: There are two possible paths to take on this, both use SKEffectNodes SKEffectNodes

问题 I've already have my vector and number of zeros and ones with this code: u=[1 1 1 1 1 0 0 0 1 1 0 0 0 0 0 0 0 1 1 1 1 1 0 0 0] transitions=(find(u~=[u(2:end), u(end)+1])); value=u(transitions) transitions(2:end)=transitions(2:end)-transitions(1:end-1) i get this value = 1 0 1 0 1 0 transitions = 5 3 2 7 5 3 Now, please if someone could help me and explain how I can get percentage of ones and percentage of zeros in my vector (all together, and by each value). Thank You very much. 回答1: If I

问题 I have draw a circle using paint and canvas in android . I want to move the circle in some direction, are there any API methods that can be used ? Or do I have to use a loop and changing the position each time? 回答1: Hi you can refer the code below, In onTouchEvent, you can handle directions and move the object. // Tutorial2D.java main activity import android.app.Activity; import android.graphics.Color; import android.os.Bundle; import android.view.Window; public class Tutorial2D extends

问题 I want to be able to change the radius of each node in my graph that i am creating using d3.js. However, i want to change the radius of each node, one at a time, and i want to able to control the delay between each change along with the sequence of the nodes. For now this is what i have in terms of code: var nodes = svg.selectAll(".node"); nodes.each(function() { d3.select(this). transition(). delay(100). attr("r", "5") }); You can replicate this simply by using the code at this link: http:/

问题 I already had another question on this issue which was successfully resolved. But now, with a slightly different example, I'm stuck again. I have two states. When I switch from A to B, it resizes correctly, but when I switch from B back to A it happens without the smooth resize transition. What am I doing wrong? Here's my code: <fx:Script> <![CDATA[ protected function rollOverHandler(event:MouseEvent):void { this.currentState = "AB"; } protected function rollOutHandler(event:MouseEvent):void
