accessibility

问题 I am new at working with the accessibility library of android i have a lot of troubles. But there is one i think is not my fault: I want to use the accessibilitynodeinfo to start a seekbar from the middle: if(mychildinfo.getClassName().toString().contains("SeekBar")){ Bundle b = new Bundle(); b.putInt(AccessibilityNodeInfo.ACTION_ARGUMENT_SELECTION_START_INT, 49); b.putInt(AccessibilityNodeInfo.ACTION_ARGUMENT_SELECTION_END_INT, 50); mychildinfo.performAction(AccessibilityNodeInfo.ACTION_SET

问题 When I add accessibilityCustomActions to an object, it works correctly on the device as far as being able to swipe up and down through the actions and select them, but there are no announcements that there are "Actions available" - should I write this in to the accessibilityLabel myself? I thought that by adding the custom actions to my object, it would announce "Actions available" automatically, or "Swipe up to select..." 回答1: I thought that by adding the custom actions to my object, it

问题 Large accessibility font size for UIButton title (.body or .headline) does not increase the frame of button but only increase the title text. It can clearly be seen in the screenshot below: Constraints are only top, leading and trailing, also in code I have added 2 lines: button.adjustsImageSizeForAccessibilityContentSizeCategory = true button.titleLabel?.numberOfLines = 0 The yellow background colour is of the button, thus identifying that only tappable area is the yellow area. I want to

问题 I want to support VoiceOver. I have an UIButton inside of an UITableViewCell . According to a best practice I have disabled the button for accessibility ( .isAccessibilityElement = false ) and implemented a custom accessibility action for the cell ( accessibilityCustomActions, NSAccessibilityCustomAction ). This way VoiceOver would not find and read the button as an own element. To make the feature behind the button accessible, I have added a custom accessibility action to the cell. With the

问题 I am trying to make my website accessible in high-contrast mode. In order to detect when high-contrast mode is enabled, I created a JavaScript method to detect if background images are disabled, because high-contrast mode disables background images. Then if the browser is in high-contrast mode, I append a CSS file to make fixes for displaying in high contrast. This works fine in Firefox, Edge, and IE, but Chrome uses its own extension to create high-contrast, and it does not disable the

问题 I've been trying to figure out how to contain the screen reader focus within a certain area. When I say screen reader focus, I don't mean the default browser focus that one can move with tabbing/shift-tabbing. I predominantly implement accessibility while using Voiceover on Mac, and when you turn that on, a new focus box appears on the page and reads out the information that it is 'highlighting'. At that point if you were to tab, both the browser and the screenreader focus move concurrently.
