hide

问题 I'm trying to create a page on my site where the Like button should be hidden if the user already likes the page. If I can't hide it, then maybe there's a way to get a callback when the like button is rendered with a user who already likes the page. This way I can hide/reveal the iframe myself. Any clues? Howie 回答1: Assuming you can echo the ids of the like buttons to the page for the likes you want hidden/get from a JSON call. var hideLikes = ["#like1", "#like2", "#like3", "#like4", "#like5"

问题 I want to hide the soft key bar (home, back, menu) when a user launches my app. I tried using: getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION); But unfortunately as soon as the user interacts with my app, the soft key bar shows again.

问题 I'm trying to display an UIImageView within a tab on an iPad. I hide the tab bar and I want the UIImageView to take up the entire screen, ie be full screen. I try resizing everything in sight and the image will not occupy the space used by the tab bar. I've tried debugging, printing the frame for each view going up the view hierarchy. Everything looks ok until it gets up to UIViewControllerWrapperView which has the smaller size. What is UIViewControllerWrapperView and how do I resize it? 回答1:

问题 I have the code below to hide/unhide entire rows depending on the corresponding cell value (hide if it's 0) and it works fine. This is a list of material and there is a 'finalize' button. At the end of the list you press the button and any item that has a quantity = 0 should hide this relevant row. It works fine. But the problem is that it's very slow. As you can see it's 400+ lines and I can literally see as the lines disappear. It's processing roughly 20 lines per second which makes it over

问题 My application support to display some screen in landscape mode, and in landscape mode, I set to hide the status bar to get mode space to display data. The problem is while hiding the status bar and rotate screen, it leave a white pace at status bar position until the screen is rotated completely as below screenshot.

问题 I have a hide/show navigation working but can't seem to figure out how to hide the main div that contains all the children divs until one of the links in the navigation is selected.

Once a link is selected, then the main div should show with only the selected child div showing as well. 回答1: I've updated
