overlay

问题 I'm creating an app where I made a custom overlay for the camera. I noticed that when I used the normal defaults for the camera, a preview comes up where you have the option to retake the photo or to use it. Is there an easy way to show that screen when working with custom overlays? Thanks! 回答1: Yes..... for this you have to create one camera overlay view programmatically . And then write this code... //set our custom overlay view imagePickerController.cameraOverlayView = overlayView;

问题 I'm writing a Windows service application in C# with FileSystemWatcher . How can I add status icons to files and folders in Windows Explorer similar to how Dropbox or SVN do it? 回答1: You should develop an overlay icon handler and register it into the system.

Custom Folder First make the folder a System Folder, then create a Desktop

问题 I need a div with picture bg to overlay an image (with some amount transparency) when hovered on. I need to be able to have one transparent overlay that can be used and reused throughout the site on any image. My first attempt was round-about to say the least. Because I found out you cannot roll-over an invisible div I devised a sandwhich system in which the original image is the first layer, the overlay is the second layer, and the original image is third layer again. This way, when you roll

问题 I would like to pop a modal dialog using jquery ui where the overlay is completely black. I know that I can set this in the theme, but I do not want all dialogs to have a black overlay. Just one of them. Is there a way to configure a dialog's background (overlay) color on a per-dialog basis? Perhaps when it is created? TIA 回答1: You can use the open and close events of the ui-dialog. $("#your-dialog").dialog( { autoOpen: false, modal: true, open: function() { $('.ui-widget-overlay').addClass(

Should I display a huge (partly transparent) image over the game activity which contains the arrow (I will need an image for each arrow for each component of the game). Edit : There's also

问题 I'm trying to develop an app for Android Nougat and I want to show some info/text in the status bar generating from a android service routine. So my problem is, I don't know how to show the text in the status bar. I added a sample image to show what exactly do I mean (red circle). I know it is possible, because I saw it in a battery monitor app from play store. I already tried NotificationCombat.Builder, but I think this is not the right way. Maybe an overlay is, but after searching I didn't
