scrolling in listview with different cell height

由 落爺英雄遲暮 提交于 2019-12-04 18:14:48
问题 I have a listview and its rows have different heights. When I scroll up, rows appear to move up or down erratically. (I don't find the behavior when I scroll down) I suspect its due to the fact listView picks one of used rows the row is placed on top of visible rows. listView changes the row's height(here erratic movement) but it's a guess. I tried googling since this should be a common problem but couldn't find any. 回答1: In this case, setting the right item height did the trick : How to set

How to size a UIStackView depending on its content?

由 半腔热情 提交于 2019-12-04 17:52:04
问题 I would like to have a similar behavior than the <Table> HTML tag, in the sense where the frame is sized according to its content. In my very context, I use an UIStackView as the content view of a UITableViewCell. As items in the cell are various information, the resulting height of the cell should be variable. My strategy is to programmatically build a cell as a UIStackView with a .Vertical axis, as in the code snippet as follows: override func tableView(tableView: UITableView,

Set html element to have 100% height on page with header

由 只愿长相守 提交于 2019-12-04 16:14:20
How can I set an html element to have a 100% height on a page that has a fixed height header? The layout is, of course, not fixed height. I already have the html and body set to simulate min-height: 100% correctly. I have tried the following ideas, but to no avail: 1. I have used the following CSS, but it uses a percentage-based height, which doesn't work well because my layout's header is a fixed 81px in height. #divContent { height: 82%; margin: 0; padding: 0; position: absolute; top: 82px; width: 950px; } 2. I have used the following in various combinations of the padding and margin, but

UITableView section header height for non-grouped table

由 て烟熏妆下的殇ゞ 提交于 2019-12-04 15:39:07
问题 Greetings! I know that UITableView sectionHeaderHeight is only used for grouped tables, but I'll ask anyway (in case there's some way to do this that isn't obvious) ... Is there a way to change the section header height (and with it, the font/size) for a NON -grouped table? Hoping "yes" or at least a "maybe" ... but fearing it might be a "no". Have at it, folks. 回答1: Yes. Use this delegate method: - (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {

Getting SVG container size in snapSVG?

由 为君一笑 提交于 2019-12-04 14:42:26
What is the correct way to get the size of the 'paper' object with SnapSVG, as soon as it has been created? My HTML looks something as follows: <div id="myContainer" style="width: 900px; height: 100px" /> And then the Javascript code: function initViewer(elementId) { var element, elementRef, snap; elementRef = '#' + elementId; element = $(elementRef); element.append('<svg style="width: ' + element.width() + 'px; height: ' + element.height() + 'px; border: solid 1px black;"/>'); snap = Snap(elementRef + ' svg'); console.log(snap.getBBox()); } What I observe here is the bounding box has '0' for

jQuery $(window).resize() not working when decreasing window's height

由 两盒软妹~` 提交于 2019-12-04 13:55:35
I have a div with an id "main", I want to set its height using jQuery and making so that on window.resize its height is modified using a function but for some reason it works well only when increasing window's height, when decreasing it it doesn't work. This is the JS: function setMainH() { var docH = $(document).height(); $("#main").height(docH - 40); } $(function() { setMainH(); }); $(window).resize(function() { setMainH(); }); EDIT: the problem appears either increasing or decreasing EDIT 2: the resize() event seem to be called correctly, I've tried with console.log("resizing"); on resizing

EditText Height Issue

由 ◇◆丶佛笑我妖孽 提交于 2019-12-04 12:52:26
I am trying to set smaller height of EditText but still have not managed it. Here is my source: <EditText android:layout_width="150dp" android:layout_height="20dp" android:singleLine="true" android:textSize="10dp" /> This code cuts out text and a white rectangular shape appears around EditText control. I have also tried maxHeight/minHeight properties, but did not worked either. If anybody have solved this issue, please help. Or is this is the bug in the android? I can not even resize Spinner, same happens as with EditText. Thanks Irfan You are probably seeing bizarre orange rectangular shapes

Xamarin.Forms ListView size to content?

由 怎甘沉沦 提交于 2019-12-04 11:23:27
问题 I have a pretty large form (adapted mainly for tablets), that has a TabbedPage nesting a ScrollView and a vertical StackPanel containing many controls. I have few occurrences where I have a ListView that contains a few single-line items, and I need it to size to content. I'd like to get rid of its scroll-bars, but anyway I don't want it to take up more space than what's required for its items. Is there a way (even an ugly one) to achieve that without have to write a renderer x3 platforms?
