scroll

问题 I need to make a credits screen ( Activity ) in my game. It would be just a vertically scrolling text lines without any images. Scrolling is to be performed automatically and no user interaction is allowed. Just like movie credits that goes from bottom to top. After the last text line has disappeared above top of the screen, it should restart. How do I do it? It is sufficient to just use TextView and animate it somehow? Or should I put that TextView into ScrollView ? What would you suggest?

问题 I am using a tableview where the first cell contains two buttons. When the first button is activated, the second should be disabled (you should not be able to press it). It all works fine until I start scrolling down the tableview. If I scroll down as far as possible while still being able to see the buttons in first cell, and I activate the first button, I am still able to press the other one. Other things also stops working, but I guess that it is cause by the same thing. Do you have any

问题 I have a big list of items / divs that I need to create programmatically , and I need to implement scrollIntoView buttons for each them. I know how to do it with refs. Whether there is an alternative to refs that might be more performant? 回答1: I believe something like this will work: onScrollClick(ev) { ev.target.scrollIntoView(); } render() { return ( ... <button onClick={this.onScrollClick}>Scroll This Element Into View</button> ) } That assumes you want to scroll the button itself into

问题 Have a site with MANY horizontally scrolling DIV containers. On one of the containers we want it to scroll to a certain position onLoad. Recommendations to what the best solution is? To complicate it a little more, the container is vertically far down (i.e. below the fold) on the page and would rather not have the onLoad result in having the page scroll vertically down to this container, merely have this specific container scrolled horizontally and nothing else. Is this also possible? Many

问题 I work on a Xamarin.Forms app that will contain a page with 2 CollectionView items: an horizontal CollectionView that will display events a vertical CollectionView that will display posts I would like that the first list is progressively hidden as soon as the user starts to scroll on the second list.
