overlay

问题 I want to create an overlay kind of layout to be displayed above an activity including toolbar. I cannot use any library to do this as everything that I've written is custom. I was able to achieve it by adding my view to decor view directly, by using this code : ViewGroup vg = (ViewGroup)(getWindow().getDecorView().getRootView()); tutorialViewContainer = (RelativeLayout) View.inflate(this, R.layout.layout_simple_overlay, null); vg.addView(tutorialViewContainer, params); but this code has an

问题 I have very limited experience with Mapview, Overlay and ItemizedOverlay. I've seen some simple code examples that use one drawable for overlays and itemizedOverlays but I'm unsure how to approach these requirements: I want more than one drawable on my map view (example: a star-icon for the map center and some other icon for other overlay items) but I want one to be unclickable (the star). Should I use both Overlay and ItemizedOverlay to achieve this? Also, my next problem is a matter of

问题 This function adds an overlay with the following properties to the entire browser screen, $('a.cell').click(function() { $('<div id = "overlay" />').appendTo('body').fadeIn("slow"); }); #overlay { background-color: black; width: 100%; height: 100%; position: fixed; top: 0; left: 0; display: none; z-index: 100; opacity: 0.5; } And this function is supposed to remove it. $('#overlay').click(function() { $(this).fadeOut("slow").remove(); }); But it seems to do absolutely nothing and now my page

问题 I trying to overlay a play icon on top of thumbnail with css, but not successful. <ul class="thumb-grid"> <li class="play-icon"><img src="image.url"/></li> </ul> You can see the icon when hovering but can't get the icon to go on top of the thumbnail. Does anyone know how? Here is the Fiddle 回答1: Use a pseudo element and change the position style. To preserve your hovering effect you can attach the :hover selector to the list item and target the img inside: html, body { margin: 0; padding: 0;

问题 I have a MapView with a toolbar button that when pushed adds overlays to the MapView. What I would like is for the button (IBAction) to check to see if there already are overlays on the map and if there are remove, if there are not, to add them. My current code that adds the overlays is as follows: - (IBAction)waterWaysAction:(id)sender { NSLog(@"WaterWays pushed"); if ([mapView overlays]) { [mapView removeOverlays:[mapView overlays]]; NSLog(@"WaterWays removed"); } else { // ******* adds the

问题 I am creating a simple interactive doll dress up game where the user can pick different attributes to assign to the doll through three separate drop down menus, such as hair colour, dress type, etc. I have a base image that is in a div which I want to overlay the images onto. <div id="display_here"> <img src="base.png" /> </div> The images are called by a function: function createDoll(userChoice) { var output = document.getElementById("display_here"); output.innerHTML = ""; var links = [

问题 I've already subclass my overlay object under the instruction of google document, and my onAdd() function is listed below: MyOverlay.onAdd() { var div_parent = document.createElement("DIV"); var div_child = document.createElement("DIV"); div_child.innerHTML = "Click Me"; div_parent.appendChild( div_child ); this.getPanes().overlayLayer.appendChild(div_parent); var this = that; google.maps.event.addDomListener( div_parent, 'click', function(){ google.maps.event.trigger(that, 'click'); // from

问题 I saw an app that overlays whole screen including nav bar (or soft-key that has back, home, etc.) today. it's CF.Lumen(requires android 4.4+) by chainfire. I just remembered this is NOT POSSIBLE on general approach and many SO answers told me. So I looked down smali codes from Lumens apk(sorry chainfire), found 0x7d6 as type specifier, which is TYPE_SYSTEM_OVERLAY . In general, this makes a view overlays on top of lock screen. It looks good however it won't overlays nav bar area. even on lock
