smooth-scrolling

In my app I have a UITableView that contains custom UITableViewCells. Scrolling is very sluggish and laggy, and I need to resolve this. Each cell contains 5-6 labels, a few buttons, and an image. I have a xib for the cell, where I place the buttons, labels, and image view, but I set all of the images in cellForRowAtIndexPath. To load the images I use [UIImage imageNamed:@""], which I read is better for optimization. I am also the reusing cells. I also found that even if I comment out and do not set the images, the table still is laggy, with just the labels set with text. Does anyone have any

I am using a ListView containing images. These images are loaded from the Internet inside the adapter. Therefore I am using the UniversalImageDownloader . Unfortunately the scrolling of the ListView "lags" for a short time as soon as I scroll down where new content has to be downloaded. I acutally expected behaviour like the ListView scrolls perfectly smooth, but the loading of the Image can of course take some more time - which should not effect the smoothness of scrolling. Furthermore, as I scroll back up the lags occur as well. It seems as if the images are not cached properly. Maybe my

How to create smooth scroll when I change the position to fixed. I try to add the animation but it does not work. Better use jquery animation(); $(window).scroll(function() { var sticky = $('.mobile-menu'), scroll = $(window).scrollTop(); if (scroll >= 40) sticky.addClass('fixed'); else sticky.removeClass('fixed'); }); header { padding: 20px 40px; background: gray; width: 100%; -webkit-transition: position 10s; -moz-transition: position 10s; -ms-transition: position 10s; -o-transition: position 10s; transition: position 10s; } section { height: 150vh; } .fixed { position: fixed; top: 0; left:

I have the smooth scrolling issue at my UITableView with UITableViewCell which contains UIImageView. Similar issues could be found all over the StrackOverflow but none of the proposed solutions helped me to completely get rid of the lag. My case is quite common: images are stored at application storage (in my sample at app bundle) images could have different size (500x500, 1000x1000, 1500x1500) I need to display those images in UITableView where UIImageView size is 120x120 (retina) I have followed multiple optimization tips and managed to optimize scrolling a lot. Unfortunately it is still not

I have a project where I use a horizontal recycler view and I want to center one element. My implementation works, but not in every case check this GIF here: As you may note it scrolls correctly if I come from the left. If I come from the right it overscrolls a lot and I have no idea how to stop nor how to fix that. I striped my code to this example here: public class DemoActivity extends ActionBarActivity implements View.OnClickListener { private static final int JUMP_TO_LEFT = MyAdapter.NON_VISIBLE_ITEMS + MyAdapter.VISIBLE_ITEMS - 1; private static final int JUMP_TO_RIGHT = MyAdapter.NON

The main scrolling commands in Vim are: Ctrl - B and Ctrl - F , as well as PageUp and PageDown scroll by full page Ctrl - U and Ctrl - D scroll half a page by default Ctrl - Y and Ctrl - E scroll one line I lose visual context every time for the former two, so I have developed the bad habit of hitting the latter ( Ctrl - Y and Ctrl - E ) repetitively. Since there is currently no first party support for smooth scrolling, what are the least objectionable workarounds/plugins? I use both Vim and GVim depending on the task, and am happy to customize them separately if there is no one really good
