问题 I need to load Bitmaps into ArrayList, then convert it to Bitmap[] and pass into ArrayAdapter to inflate ListView. I use UniversalImageLoader library and here is my code: final ArrayList<Bitmap> imgArray = new ArrayList<>(); //before the method scope, as a class field //...some code... File cacheDir = StorageUtils.getOwnCacheDirectory( getApplicationContext(), "/sdcard/Android/data/random_folder_for_cache"); DisplayImageOptions options = new DisplayImageOptions.Builder() .cacheInMemory(true)

问题 I have a webpage that uses HTML LocalStorage. It is common to have multiple tabs/windows of this page open at the same time. Since these all use the same LocalStorage and LocalStorage does not provide transactions or similar, I would like to implement some form of mutual exclusion to prevent the different tabs/windows to overwrite each other's data in an uncontrolled manner. I tried to just port my test of the Burns/Lynch mutual exclusion algorithm to the browser by simply storing the boolean

问题 I'm trying to build a metronome with Typescript (and Angular 2). Thanks, to @Nitzan-Tomer (Typescript Loop with Delay), who helped me with the basics. Now I'm facing the issue, that after I started the metronome, I'm not able to change the interval. Imagine a slider, changing the speed between the sounds (=> interval). let theLoop: (i: number) => void = (i: number) => { setTimeout(() => { metronome.play(); if (--i) { theLoop(i); } }, 3000); }; theLoop(10); The interval here is 3000. And I

问题 Hope you all are well. This is my first post. I am trying to write a script in Ruby using Cucumber and the Selenium 2 framework. I am trying to find out how to click on any given link on a hover based component. The sainsbury's website http://www.sainsburys-live-well-for-less.co.uk/ is the perfect example. If you select the first link i.e. Recipes and Insprirations followed by Lets get backing then you are redirected to a new page. I want to do this through a script. Currently I am having

问题 This question was migrated from Electrical Engineering Stack Exchange because it can be answered on Stack Overflow. Migrated 4 years ago . I am working on an assembly program (8086) that plays music on the PC speaker. Everything works fine but I've got one problem. Program falls in endless sleep (with speaker on) on 78th note, no matter what note it is. I am using 86h function of 15 interrupt . So why does that endless sleep occur, and how to fix that? Here's the code (with Mortal Kombat

问题 I am trying to run a query: INSERT INTO `ProductState` (`ProductId`, `ChangedOn`, `State`) SELECT t.`ProductId`, t.`ProcessedOn`, \'Activated\' FROM `tmpImport` t LEFT JOIN `Product` p ON t.`ProductId` = p.`Id` WHERE p.`Id` IS NULL ON DUPLICATE KEY UPDATE `ChangedOn` = VALUES(`ChangedOn`) (I am not quite sure the query is correct, but it appears to be working), however I am running into the following issue. I am running this query before creating the entry into the 'Products' table and am

问题 What is the difference between app.delay(20); tableViewCell.waitForInvalid(); and app.pushTimeout(20); tableViewCell.waitForInvalid(); UIATarget.localTarget().popTimeout(); In the second case, in case if the cell becomes invalid in say 2secs, then will it still wait for 18secs and then continue or just continue after 2secs ? In the first case, it is waiting until 20secs. 回答1: No, the second case is preferred because it will wait up to 20 seconds for the cell to become invalid. The first case,

问题 To be as fast as possible, I will jump into the topic right now. I want to delay the script before jQuery is loaded. Here is my problem: I have code which inserts jQuery.js automatically when jQuery isn't loaded yet: if(typeof jQuery=="undefined") { var s=document.createElement("script"); s.type="text/javascript"; s.async=true; s.src="http://code.jquery.com/jquery-1.5.1.min.js"; var x=document.getElementsByTagName("script")[0]; x.parentNode.insertBefore(s, x); } $(document).ready(function() {

问题 $("#div_game_container").on("click", ".square", squareClick); function squareClick() { var group = $(this).data("group"); if ($("." + group).hasClass("active")) { // off click event $("#div_game_container").off("click", ".square", squareClick); $("." + group).each(function (index) { $(this).delay(100 * index).fadeOut(100); }); // on click event. this line does not wait "each" function $("#div_game_container").on("click", ".square", squareClick); } above code does not work. Actually, it works

问题 I want to write a javascript function that takes very close to 5 seconds to run. How can I make that guarantee? I have tried function wait(numSeconds) { var end = new Date().getMilliseconds() + numSeconds * 1000; while (new Date().getMilliseconds() <= end) {} } but this just crashes the page. 回答1: you can use: var t = setTimeout(function(){alert('done')},5000); 回答2: You cannot freeze the page without freezing the page. You're trying to write a function that runs for 5 seconds straight.
