accessibility

问题 I'm trying to customise the talkback output for items in a RecyclerView. I have modified the onBindViewHolder method to include the following code itemView?.setAccessibilityDelegate(object: View.AccessibilityDelegate() { override fun onPopulateAccessibilityEvent(host: View?, event: AccessibilityEvent?) { super.onPopulateAccessibilityEvent(host, event) event?.let {event -> if (event.eventType == AccessibilityEvent.TYPE_VIEW_ACCESSIBILITY_FOCUSED) { event.text.add("Hello world!") } } } })

问题 From MDN: In the example below, a button is styled to look like a typical "close" button, with an X in the middle. Since there is nothing indicating that the purpose of the button is to close the dialog, the aria-label attribute is used to provide the label to any assistive technologies. <button aria-label="Close" onclick="myDialog.close()">X</button> According to the Bootstrap Documentation: Hide an element to all devices except screen readers with .sr-only So I guess I could also write:

问题 If I use the following: -webkit-touch-callout: none; -webkit-user-select: none; -khtml-user-select: none; -moz-user-select: none; -ms-user-select: none; user-select: none; I can disable text selection of certain elements on my web page. Works well for buttons and links which don't give as nice a UX if selected (obviously opinion). Am I free to use this wherever I feel necessary? Or are there accessibility implications? i.e. do screen readers and other tools rely on text selection? Note: I'm

问题 When a view has event click and enable talkback. I need to disable the audio "double to tap" in the view. I am using accessibility in android development. How can I do this, please? 回答1: If you check google talkback source code at this line and here, string resource ("double tap") has been used here and here So, you should remove AccessibilityActionCompat.ACTION_CLICK action and set isClickable to false in node info. ViewCompat.setAccessibilityDelegate(view, object :

问题 I'm working on a site that needs to (a) work without JavaScript and (b) be keyboard-accessible. I have used the label target trick to build a tab view (https://css-tricks.com/functional-css-tabs-revisited/), but I've noticed that it relies on the label being clicked. I can't figure out how to make it work with the keyboard. Is this possible? .tabs { background-color: #eee; min-height: 400px; } .tabs__list { border-bottom: 1px solid black; display: flex; flex-direction: row; list-style: none;

问题 Context: We have some cards that are radio buttons in a radio group, that we want to display in a different order for small and large breakpoints. I want to know if there is a way to do this nicely that doesn't involve duplicating the html for the different breakpoints, and doesn't break accessibility. Desired large breakpoint: |Large|Medium|Small| Desired small breakpoint: |Small| |Medium| |Large| Desired accessibility behaviour: With a radio group, you'd normally expect to hit tab to get to

问题 I am working on accessibility fixes for an Angular project at work. I am facing an issue accessing a modal. I have a main component which opens another component on top of it covering half the screen. That component opens a modal on button click. This modal is not accessible by tab. And even weirder, the tabindex=0 that you see assigned in the code below automatically gets assigned tabindex=-1 when the modal appears on screen. Even the buttons, which don't even have a tabindex attribute
