问题 When VoiceOver is active on an iOS device, the single-finger swipe(left or right) gesture allows users to browse the different elements in the view. Is there a way to detect if a user used the single-finger swipe gesture when using voiceover? 回答1: You might be asking either of 2 things: You want to know when the VoiceOver user successfully issued the single-finger swipe left/right gesture to VoiceOver - VoiceOver will process ("steal") the gesture from your code and do its thing (move

问题 Is there a way to add something on selected page on a web site that said to people using accessible software, like NVDA, to go to the page X for full accessibility.

问题 Currently I am working on a game for people with accessibility restrictions. I am having the issue of locking the player model in a sitting position. If the user does not center themselves in the room the player model will be pulled to a certain direction. I would like to lock the player model in a seat and only allow for arm movements and head rotations, no leaning or moving in the game using the HMD. Since I am using the Final VR IK asset I have tried using their demo for sitting position

问题 I have a TextBlock and I want to track that control from Screen reader and whenever a new value is set to the control in code, the screen reader should readout the new text.

问题 Say I have a set of radio <input> s. I'm not a caveman, so I know I need to associate <label> with those <input> s. I'm fond of wrapping the radio buttons within their corresponding labels, for reasons enumerated here. So, for example: <fieldset> <legend>Should I provide a "for" attribute?</legend> <label><input type="radio" name="define_the_for_attribute" id="define_the_for_attribute_yes" value="yes" />Yep, if you know what's good for you</label> <label><input type="radio" name="define_the

问题 In our current UI, next to certain labels, we have a help-tip button that when clicked, explains the details of what the label references. As such, VoiceOver identifies these two items as separate accessibility items. However, when using accessibility, we're hoping we can just do everything in the label itself. This way when the label gets focused, the user will here 'Account value, $20 (the accessibilityLabel), double-tap for help (the accessibilityHint)' However, unlike a button, a label

问题 Our app is ran from SU or normal user. We have a library we have connected to our project. In that library there is a function we want to call. We have a folder called notRestricted in the directory where we run application from. We have created a new thread. We want to limit access of the thread to file system. What we want to do is simple - call that function but limit its access to write only to that folder (we prefer to let it read from anywhere app can read from). Update: So I see that

问题 How can I detect if 'High Contrast' setting (available on Android 5.0+) is enabled in Accessibility settings? 回答1: In the AccessibilityManager class (see source here) you have a public method called isHighTextContrastEnabled that you can use to get your information: /** * Returns if the high text contrast in the system is enabled. * <p> * <strong>Note:</strong> You need to query this only if you application is * doing its own rendering and does not rely on the platform rendering pipeline. * <
