overlay

问题 I 've been trying to add a half circle to a map view using a custom MKOverlayPathView subclass and a custom class which confirms to but I cannot get anything to show up on the map view. I use a UIBezierPath to create the path for the circle, but no matter what I try, I cannot see my path... Does anyone have an example program in which a UIBezierPath is being used as overlay? Thank you! Tim Edit: Answer to Anna's question: I can draw MKCircleViews without any problem, but I seem to struggle

问题 I adopted the code from this answer in order to draw an overlay window, which stays on top of all windows, always. But I find that this window keeps flickering whenever there is a keypress or a button click. I wanted to know if this can be stopped somehow. Increasing the time did not help me, as my terminal was frozen for few seconds when I increased time to 5000000000 The code was tested on Ubuntu 16.04 LTS . 回答1: I could not find a solution using the XComposite suite of functions. However,

问题 I'm half way there with this issue but have become stuck. I believe similar issues have been raised in the past but nothing quite what I'm looking for. I currently have some demo code on jsFiddle which can be viewed here: http://jsfiddle.net/WolfHook/jb36D/ HTML <div id="thumbsContainer"> <div class="imageHolder"> Image in Here... </div> <div class="imageHolder"> Image in Here... </div> <div class="imageHolder"> Image in Here... </div> CSS #thumbsContainer { background:#000; padding:20px;

问题 I have a JFrame with a panel on it with Overlay Layout because I want to set a JLabel with an image as the background and put stuff over top of it. I set the size of the frame equal to the size of the image and when I put only that on it fits perfectly, but if I add anything over top of it it shifts the image to the right by the width of the component that I add and cuts it off to the right. It does this even though the component isn't in the region that is shifted over. The component is to

问题 How can I overlay a search bar over MapKit? I like how the new Google Maps application has a search box and buttons that hover over the map. See the image on the left: I'm not sure how to get this however as I have not been programming iOS for longer than a couple of weeks. Any ideas on how I could hover UI elements on top of each other with Storyboards/Objective-C? Presumably it's a navigation bar that has been made invisible but how is this done, and how is it the Map appears underneath it?

问题 I am an iOS developer and I have written an app for a client, it is a fitness (Crossfit) timer app, it films you on your workout and adds real time overlays and rep counts to the finished video. It was a fairly challenging project to complete and I was just wondering if the same thing would be possible on Android? Essentially what I need to know is, is it possible to overlay text that changes (e.g a timer counting up in seconds) onto a recorded video? If anyone has written an app that does

问题 I have already written an app that uses GoogleMaps Api v1 in Android. This app uses several Overlays (or ItemizedOverlays ) which handle a bunch of things autonomously (ie. lazy loading markers, as I have a whole lot of them and adding them all at once will force the app to close). I also use them as an interface for the user: He can decide which overlays (or which kind of markers from his perspective) he wants to see. I add or remove these Overlays accordingly. Now I want to switch to the

问题 Is there a way to affect the styling of the copyright part in google maps API v3? I'd like to move it up by 10 pixels for example, since I have some overlapping right now and it doesn't show up (and that's contrary to the Terms of service). Any ideas would be appreciated. 回答1: I have never come across away, and i very much doubt there is, google dont own copyright to all there maps and would probably have legal agreements with other map providers. It just would not be worth it for them. Out

问题 I have a problem with mapview and Overlay. I must to draw a circle on the map everytime that change GPS position. I used the method draw in my overlay class that extend overlay. The problem is that I must draw these circles with transparency, but when the circles overlap each other in the intersection point the color it's different because there is a sum of alpha. How I can fix it? This is my overlay class: public class ImpactOverlay extends Overlay { private static int CIRCLERADIUS = 0;

问题 I have taken the Cell Table example from google developer's guide and made the following changes: Use overlays instead of Java POJOs Use a EditTextCell to edit one column For my surprise, when running the code the Cell Table is adding an extra property to the overlay objects pushed into it. They should look like: {"name":"John", "address":"123 Fourth Road"} {"name":"Mary", "address":"222 Lancer Lane"} But instead they look like: {"name":"John", "address":"123 Fourth Road", "$H":1} {"name":
