talkback

I'm trying to execute/receive a onfocus HTML event using Talkback on an Android Device (Moto G Android 4.4.3) on an HTML page while selecting an input field. I created on single input text with an onfocus event : this event never get called when using "touch explorer" with talkback. When I select/hover it with Talkback there is a little outline over my field it but it's not the HTML :focus state : <input type="text" id="myInput" onfocus="focusFunction()" onblur="blurFunction()"> See this fiddle for an example : https://jsfiddle.net/hpgqmz7f/embedded/result/ On IOS + VoiceOver or Chrome@PC +

As the title says, Android Talkback is not registering the onFocus event. I understand that the onFocus event is not ever registered since the screen reader is using a special type of accessibility focus . How, then, can we drive/manipulate the accessibility focus to provide the user a better experience? I have an example here: https://codesandbox.io/s/r54j2mqrl4 . So here the console.log("hello!") is not registering for me in mobile Android Talkback, however it is registering correctly on desktop mac OSX(with no screen reader on). I am using the tab key to navigate. Is there something similar

I'm implementing custom keyboard (through custom view) for password field and trying add accessibility feature, so when user single press on view it should pronounce selected value. In my custom keyboard I need coordinates from MotionEvent so view can calculate on what draw (value) it was pressed. But in this case when Talkback enabled onTouchEvent method is not called. It calls only when user double tap on view. Im trying to add custom OnTouchListener but it does not work. setFocusable=true and setFocusableInTouchMode=true . When TalkBack is enabled a double tap is the equivalent of a single

My Android app contains a custom slider control based on the SeekBar , and I want to attach a custom text phrase to my control to explain its use for Accessibility. I have done this successfully using View.setContentDescription(text) , and TalkBack correctly speaks the phrase when I request focus on my slider control from Activity.onCreate . So far, so good. However, when I touch the control, which I believe sets the AccessibilityFocus on my Android API 16 test device, extra words are being added to the spoken phrase, i.e. '...seek control. 0 per cent'. I want to remove these additional words.

This question asked how to know if Android Talkback is active; that worked until Jelly Bean. Starting from Android 4.1, that steps no longer work, because the mentioned cursor is empty. Having this said, I want to ask is if there is a way to do the same checking in Jelly Bean. EDIT I tried to search for TalkBack code and I found it here . For checking if TalkBack is active, I am using the following code: Intent screenReaderIntent = new Intent("android.accessibilityservice.AccessibilityService"); screenReaderIntent.addCategory("android.accessibilityservice.category.FEEDBACK_SPOKEN"); List

By default, clickable Views on Android will be rendered with a usage hint that's read aloud (if TalkBack is enabled and the user focuses on that View) after the content description: "Double tap to activate" Can I change this so it reads out something less abstract and more specific to my app? Like: "Double tap to play video" Yes, this is absolutely possible! Overriding the onInitializeAccessibilityNodeInfo method If you have a custom View, you can override the onInitializeAccessibilityNodeInfo(AccessibilityNodeInfo info) method and add an action with the ACTION_CLICK ID, to override the label:
